Aberrant: 
Behaviour that is significantly different from what is accepted as usual or normal in a society or culture.

Abnormal Behaviour:    Behaviour that is significantly different from what is accepted as usual or normal in a society or culture.

Across modalities: In teaching terms, this means teaching methods that use  more than one of the  sensory channels,   such as visual (seeing), auditory (hearing), tactile (touch), and kinesthetic (movement).   Also known as multi-sensory teaching.

Analysis of Verbal Behavior (AVB):  “an applied behavior analysis approach that is used to teach communication.  AVB employs the many effective procedures based on ABA (e.g., reinforcement, prompting, fading, task analysis).  A major feature is the use of Skinner’s (1957) analysis of the functions of language (e.g., to request, to name things, to refer to things not immediately present), which departs from a developmentally based language approach.  The functional analysis of language is a major approach for teaching communication skills to children with autism.  ( John T. Neisworth & Pamela S. Wolfe” ,The Autism Encyclopedia, Paul H. Brookes Publishing Co. Inc. 2005)

ADI: Autism Diagnostic Interview – Revised:  The Autism Diagnostic Interview-Revised (ADI-R) is an instrument used in the diagnosis of autism spectrum disorders in children and adults.    The assessor interviews the parent or caregiver to obtain detailed descriptions of past and current behaviours that are relevant to a diagnosis of ASD.   The interview focuses on developmental delays, social interactions, language, non-verbal communication, play, understanding and expression of emotions, and on restricted, repetitive and stereotypic behaviours and interests.  It is currently considered to be a ‘Gold Standard’ tool for use in the diagnosis of autism. It is usually used in conjunction with the ADOS (see below).

ADOS-G: Autism Diagnostic Observational Schedule:   The ADOS is an instrument used in the diagnosis of autism spectrum disorders in children and adults. It consists of a series of semi-structured play and social interactions with young children, and interview questions for adolescents and adults. The activities provide opportunities to observe the child or youth’s communicative behaviours, social interactions, imaginative play, emotional expression, stereotyped behaviours, or other behaviours that are relevant to the diagnosis of autism spectrum disorders.  It is currently considered to be a “Gold Standard” tool for use in the diagnosis of autism.

Advocate:  Someone who takes action to help someone else (as in “educational advocate”); also, to take action on someone’s behalf.

Alert Program:  a specific program that is used to help teach self-regulation awareness. The program supports children, teachers, parents and therapists to choose appropriate strategies to change or maintain states of alertness.  This program is described more fully in a book called How Does Your Engine Run? A Leader’s Guide to the Alert Program for Self-Regulation (Williams & Shellenberger, 1996)

Angelman Syndrome:  “A rare genetic disorder that causes severe learning difficulties. The children show characteristics such as: happy appearance (smiles and laughs a lot), hand flapping, excitable personality, balance problems, short attention span, developmental delay, and speech impairment with better receptive language skills. The incidence is believed to be 1 in 25,000 children. (http://ghr.nlm.nih.gov/condition/angelman-syndrome)

Antipsychotic Drugs:  Drugs which help counteract or reverse psychosis, a disturbance in thought processing and behaviour leading to a loss of contact with reality.

Anxiety: 
a cluster of negative emotions such as apprehension, fear and worry that can occur with physical responses like chest pain, stomach pains or shortness of breath. 

Aphasia
:  The complete or partial loss of ability to use or understand language as a result of
brain damage.

Applied Behavioural Analysis – ABA
:  Applied Behavior Analysis is a scientific and professional discipline that is concerned with applying scientific principles of learning and behavior to socially important problems.  It emphasizes careful measurement of observed behaviour, and analysis of behavior in terms of its relationship to events in the environment that immediately precede or follow
the behavior.

An Applied Behavior Analysis program establishes behavioral objectives or goals, breaks complex behaviors down into their functional parts, sets objective ways of measuring the relevant behaviors, implements teaching or behavior change procedures based on behavioral principles, and then evaluates the results through careful experimentation. ABA teaching methods are very systematic and precise.

Applied Behavior Analysis is a very broad field, and ABA principles and methods have been used for everything from developing language skills in children to teaching leadership skills to executives, and from eliminating self-injurious behaviour to reducing littering. Applied Behavior Analysis methods are known to be effective in treating autism, and are used to promote the child’s optimal development in all domains including motor skills, self-care, language and communication, play and social skills, pre-academic and academic skills, and vocational and independence skills. Communication and social skills are given special emphasis. ABA techniques are also used to reduce challenging behaviors.

Some methods used in autism treatment which are based on ABA principles include:  Discrete Trial Teaching, Precision Teaching, Programmed Instruction, Pivotal Response Training, Verbal Behavior approaches, Fluency Training, Incidental Teaching, and Positive Behavioural Support. (Batstone, David, Queen Alexandra Centre, Vancouver Island Health Authority)

Apraxia: A neurological disorder where a person loses the ability to move in a way they want despite the fact that there is no loss of muscular power, coordination or sensation.  Apraxia may be specific to speech.

Asperger Syndrome (AS):  A developmental disorder on the autism spectrum. People with AS have average or above average intelligence and had no significant delay in language development.  People with Asperger Syndrome have difficulty with social understanding, and their patterns of behaviour are often inflexible.  They commonly have a very narrow range of interests with intense preoccupations in these interests.  Many people with AS have challenges with motor planning and motor skills.

Assessment:  An organized process of gathering of information about a child’s needs, abilities, and behaviours in order to determine a diagnosis or to address an identified problem or question.  This process may include the use of formal tests, interviews, direct observation, and review of medical or other background information.   The assessment results are used to plan appropriate treatment, education, or support services.

Assistive Technology:  Assistive Technology includes any item or piece of equipment used to maintain, increase or improve the functional capabilities of individuals with disabilities.

Attention:   The mental process of selectively concentrating on one thing while ignoring other things.

Attention deficit hyperactivity disorder (ADHD):   A neurological condition with specific chronic core symptoms including distractibility disorganized thinking, poor impulse control, mood shifts, forgetfulness and hyperactivity.  These symptoms vary in different situations and at different times. Common secondary symptoms include perceptual and emotional immaturity, poor social skills, disruptive behaviours and academic problems.  ADHD is believed to affect 3 – 5% of the population.

Atypical autism: A term used in the International Statistical Classification of Diseases and Related Heath Problems –  Tenth Revision (ICD -10) to describe a condition that differs from autism in terms of either age of onset (an Autistic Disorder diagnosis requires that symptoms are apparent before the age of three) or failure to meet the  criteria for  Autism in all three areas: reciprocal social interaction, verbal and non-verbal communication, and stereotyped behaviours or restricted interests.  In the Diagnostic and Statistical Manual of Mental Disorders – Fourth Edition (DSM IV) it is called Pervasive Developmental Disorder – Not Otherwise Specified (PDD NOS).

Auditory Processing Disorder: Auditory processing is a term used to describe the brain processes involved in recognizing and interpreting sounds.  An auditory processing disorder is impairment in the ability to process or interpret information that is heard.  This is not just a problem in understanding words and language, but also in interpreting other sounds in the environment.

Auditory Integration Training (AIT): “AIT is an intervention in which the service provider identifies sounds to which the participant is believed to be over- or under-sensitive. Then music with selected high and low frequencies is presented via headphones to the participant. Certain frequencies, such as those to which the participant is over- or under-sensitive, may be completely or partially filtered from the music. In Auditory Processing Training, speech sounds are dilated or expanded (i.e., presented more slowly than in typical speech), and then compressed as the student progresses. Examples: Tomatis method, Bernard Method, Earobics, FastForward.  The 2002 American Speech and Hearing Association Work Group on AIT, after reviewing empirical research in the area to date, conclude that AIT has not met scientific standards for efficacy that would justify its practice by audiologists and speech-language pathologists.” (www.autismcanada.org/auditoryinte.htm)

Augmentative communication:  “Refers to methods of communication to either enhance or replace conventional forms of communication (spoken language). Individuals with significant impairment in communication skills may rely on augmentative communication systems to express their needs, wants, and feelings. There are a variety of augmentative communication systems that are available including gestures, sign language, picture exchange (such as PECS), pointing to pictures, and electronic devices that include voice output. Each system has unique advantages and disadvantages so the ultimate choose of a system should be predicated on a complete evaluation. Such an evaluation should consider the individual’s existing skills, his/her communication needs, and the skills needed to interact with others.” (Association for Science in Autism Treatment http://www.asatonline.org/intervention/treatments/augmentative.htm) a(9

Autistic Disorder: “(Also called autism.) – a neurological and developmental disorder that usually appears during the first three years of life. A child with autism appears to live in his/her own world, showing little interest in others, and a lack of social awareness. The focus of an autistic child is a consistent routine and includes an interest in repeating odd and peculiar behaviors. Autistic children often have problems in communication, avoid eye contact, and show limited attachment to others.”
(Yale Medical Group ymghealthinfo.org/content.asp?pageid=P02566)

Autism Behaviour Checklist (ABC):   A screening test for autism that is completed by a parent or a teacher.  Screening is used prior to a full and detailed diagnostic assessment.  This screening instrument is primarily used for the school aged population with severe disabilities.  For more information about screening tools see http://www.nyhealth.gov/community/infants_children/early_intervention/disorders/autism/screenin.htm

Autism Observation Scale for Infants (AOSI):  a testing instrument developed in Canada used to measure the autism-related behaviours in infants to assess an infant/toddler’s risk of later developing autism.  For more information see the Canadian Autism Intervention Research Network article http://www.cairn-site.com/en/glossary/glossary.html.

Autistic savant:   An individual with autism who displays an exceptional skill in some limited field (e.g., music, math).  For more information and examples see http://www.wisconsinmedicalsociety.org/savant_syndrome/savant_articles/autistic_savant.

Autism Spectrum Disorder (ASD):  Autism is often referred to as a “spectrum disorder,” meaning that the symptoms and characteristics of autism can present themselves in a variety of combinations, ranging from mild to severe. The Autistic Spectrum includes Autistic Disorder (AD), Asperger Syndrome, (AS), and Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS). Childhood Disintegrative Disorder and Retts Disorder are not usually considered part of the Autistic Spectrum, although they are grouped with them in the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV).

Aversives:  In non-technical terms, an “aversive” is an unpleasant event or object that a person will actively seek to avoid. Aversive consequences are known as “punishers” when they are given as a consequence of a behaviour and this results in the behaviour occurring less frequently.  The term “punisher” is a technical term used in behavioral therapy and does not imply the use of physical aversives such as hitting, slapping, spanking, or pinching.”  Mild verbal disapproval or withholding a desired object or activity might also function as “punishers” for young children.   The use of physical aversives is not recommended or appropriate as a part of a behavioral intervention program, and behavioral intervention programs can be successful without their use. (Clinical Practice Guideline Report of the Guideline Recommendations Autism / Pervasive Developmental Disorders Assessment and Intervention for Young Children (Age 0-3 Years) Sponsored by New York State Department of Health Early Intervention Program http://www.health.state.ny.us/community/infants_children/early_intervention/disorders/autism/)

B

B Vitamins:
The B Vitamins are sometimes used in autism treatment by those advocating a bio-medical approach. “A 2003 study entitled Combined vitamin B6-magnesium treatment in autism spectrum disorder by Nye and Brice found that “There is no evidence of an acceptably high level to state that a combination of Vitamin B6 and magnesium improves the behaviour or social and communication skills of children and adults with autism.” (Canadian Autism Intervention Research Network http://www.cairn-site.com/en/documents/abstracts/intervention04.html)

Behavior-based programs:  Treatment methods that are based on behavioral science or the principles and methods of Applied Behavior Analysis (ABA).  ABA is a well-researched, intensive method of treatment which has been shown to result in great improvement for many people with ASD symptoms. (See ABA)

Behavior Consultant:  Refers to the person responsible for the design and development of the child’s behavioral plan of intervention and for the ongoing supervision of that plan.

Behavior Interventionist (BI): Refers to a person of the parent’s choice, such as a child care worker, who works with the child to achieve goals ideally set out by a behavioral consultant. This person usually works one-on-one with a child and ideally has experience with children with Autism Spectrum Disorder. In BC this person much be 19 years or older and have a clear criminal record check.

Behavioral Plan of Intervention:  A plan developed by a qualified behavior consultant, with parental input, that promotes developmental growth with both broad and specific goals related to improving daily living skills and increasing independence in a social or school environment. The plan is used by a family in deciding what services are needed and what goals should be reached through those services.  According to Ministry of Children and Family Development policy regarding children under 6 with ASD a behavior plan of intervention must be developed within 90 days of enrolling for autism treatment funding from the Province.

Berard Auditory Integration Training (called Berard AIT or AIT):

Central Auditory Processing Disorder: 
Central Auditory Processing Disorder (CAPD) is a learning disability in which an individual hears sounds but cannot process them correctly into words and language. People with CAPD may have trouble understanding what they hear, acting on it quickly, remembering it for a short or long time, and formulating a verbal response. Speech-language pathologists and audiologists are often involved in the diagnosis and treatment of auditory processing problems.

Central Coherence: Individuals with autism spectrum disorders are said to have “weak central coherence”, which is the capacity to integrate information to make sense of one’s environment. People with autism tend to focus on details and process information in a piece-meal fashion, rather than focusing on the context and overall meaning of a situation (They have trouble understanding the gist, the “whole picture”, or the gestalt).

Central Nervous System:  The control centre of the body, made up of the brain and the
spinal cord.

Chelation:   A process used to remove heavy metals from the body.  Specific products called chelating agents are ingested, heavy metals such as lead, copper, or mercury bind to the product, and they are then eliminated by the body.  The purpose of chelation is to reduce the toxic effects of the heavy metal on the body and nervous system. Chelation is a recognized treatment for certain medical conditions, but its use as a treatment for autism is controversial and considered by many to be unsafe.  See www.autism-watch.org/

Cerebellum:  A structure in the lower back part of the brain responsible for functions such as maintaining balance and coordinating and controlling voluntary muscle movement.

Cerebral Cortex:  The outer layer of gray matter of the brain where higher brain functions take place, such as sensation, voluntary movement, thought, reasoning, and memory.

Child Psychologist: A mental health professional, usually with a Ph.D. in Psychology, who administers and interprets psychological tests, evaluates and treats the emotional, developmental, and behavioral disorders of children. Psychologists cannot prescribe medication.

Childhood Autism Rating Scale (CARS):   A brief rating scale that measures the severity of autism in a child over 2 years of age, based on ratings of fifteen individual behavioral characteristics.  The total score may fall in the “non-autistic,” “autistic,” or “severely autistic” ranges.  It is normally based on the professional’s own observations of the child’s behavior, although some information may be obtained by interviewing a parent or caregiver.  Special training is required to use the CARS.

Childhood Disintegrative Disorder:   A relatively rare condition that resembles autism occurring in 3- and 4-year-olds characterized by a deterioration of intellectual, social, and language functioning from previously normal functioning.  A Pervasive Developmental Disorder although not included as an Autism Spectrum Disorder.  For more information see http://childstudycenter.yale.edu/autism/information/cdd.aspx.

Chromosome:   A structure (typically 46 in humans) in the cell nucleus that is the bearer of genes.

Co-existing Disorders:  In addition to cognitive impairments, individuals with ASD often suffer from multiple psychopathologies. These include impulse-control disorders, psychoses, obsessive-compulsive disorder, seizures, mood and anxiety disorders, and developmental delays. Also called Co-morbid Disorders or Differential Diagnosis or Dual Diagnosis.

Cognition:  The process of ‘thinking’, including, perception, reasoning, problem solving, and memory.

Cognitive:  The ability to execute daily tasks in a functional manner. This includes the ability to remember short and long term events, to sequence activities, to reason, to think logically and safely, to categorize, etc.

Cognitive Behavioral Therapy:  A treatment that combines behavior therapy with cognitive therapy and that works to reduce habitual reactions to challenging situations.  CBT assists the person in learning how certain ways of thinking may cause or contribute to feelings of anxiousness, depression or anger that in turn lead to negative behavior.  Recent research has indicated that positive results may be seen from using CBT with some people with high functioning autism. This treatment is conducted by a trained psychologist and may be used with verbally fluent children, adolescents, or adults.

Co-morbidity:  When a person has two or more different conditions at the same time, these conditions are said to be co-morbid. For example, a person can have both Fragile X syndrome and Autism, or an Anxiety Disorder and Autism. (See also: Co-existing Disorders).

Communication Disorder: Any interference with a person’s ability to comprehend or express ideas, experiences, knowledge, or feelings.

Compulsion:  An uncontrollable impulse or urge to perform an act, often repetitively, and usually to avoid or alleviate anxiety.

Congenital:  A condition that is present from birth.

Consultation: Case discussion and evaluation focusi ng on data, goals, objectives, and therapy techniques to be used.

Cranio-sacral Therapy (CST):  Using a soft touch, therapists relieve blockages in the craniosacral system, the membranes and cerebrospinal fluid that surrounds the brain and spinal cord, to improve the functioning of the central nervous system.  This therapy is controversial.  See http://quackwatch.org/01QuackeryRelatedTopics/cranial.html

Curriculum:   An organized set of specific course objectives which are often expressed in terms of learning outcomes.

D

Daily Schedule:   
A structured outline of activities for the day that provides predictability and assists a person in making transitions from one activity to the next.  A Daily Schedule is useful for maximizing “on task” (i.e. engaged) behavior and minimizing inappropriate behavior.  A Daily Schedule may be in a written or a visual form.

Data Collection:  Data collection refers to the process of gathering specific, objective information about a person’s academic or behavioral performance. Data is usually in a quantitative form, such as the number of times a behavior occurs, percentage correct in a task, amount of work completed, etc.  Collecting and analyzing data helps an instructor to evaluate a program’s effectiveness. By collecting and analyzing data on a systematic basis, an instructor knows when to make changes in both academic and behavioral programs. Data collection has two critical components: information gathering and decision making. Information gathering may involve curriculum-based assessment, observing classroom behavior, grading papers, or parent interviews. The more structured and systematic the process, the more valid the information. Once the data is collected, the instructor must analyze it and then make decisions based on that information. Decisions might be made regarding changes in curriculum, teaching strategies and techniques, or the management of specific classroom behaviors.

Developmental:  Relating to the process of growth, maturation, or progressive change in a person as they age.

Developmentally Delayed (DD):  An informal term used to describe the development of children who are not able to perform the skills that other children of the same age are usually able to perform, or who accomplish developmental “milestones” (sitting, walking, first words, etc.) at a significantly slower pace than average. A preferred term by many instead of the medical term ‘mental retardation’.

Developmental Language Disorder:
 Children have language disorders when they have problems expressing their thoughts or understanding written material or what others say. The disorder is developmental when it presents itself as the child is growing and is not the result of injury.

Developmental Disability:  Defined as “measured intellectual functioning of approximately 70 IQ or lower, with onset before age 18, and measured significant limitations in two or more adaptive skill areas.” Eligibility criteria reflect the internationally accepted definition of developmental disability including IQ measurement of 70 [with a standard error of 3-5 points] and the key role adaptive skills play in both the definition and determination of eligibility for services. (Community Living BC www.communitylivingbc.ca/policies-publications/policies/)

Developmental Level:   “A method of observing how children achieved particular developmental milestones, particularly those related to a child’s ability to stay engaged, express mutual pleasure and attention, to engage in complex problem solving and symbolic play, and to link ideas.”(The Interdisciplinary Council on Developmental and Learning www.monarchschool.org/ParentsGlossary.html#CD)

Developmental Regression:   “A form of autism in which infants, after apparently normal development, start to loose language and other skills. This condition is fairly rare and has not been well described, nor does it have scientifically established standards for diagnosis.” (Canadian Autism Research Networkhttp://www.cairn-site.com/en/glossary/glossary.html)

Discrete Trials: Discrete Trial teaching is a specific method of teaching used to maximize learning.  It is a teaching technique or process used to develop many skills, including cognitive, communication, play, social and self help skills.  It is just good teaching.  The teaching strategy involves:

  1. - Breaking skills into the smallest steps
  2. - Teaching each step of the skill intensively until mastered
  3. - Providing lots of repetition
  4. - Prompting the correct response and fading the prompts as soon as possible and
  5. - Using positive reinforcement procedures.

A therapy session uses repeated trials (or presentations) with each trial having a DISTINCTLY identifiable beginning, middle and end.  So the trial is “Discrete” in that it is distinct and it has clearly identifiable steps and a conclusion.  Each step of a skill is mastered before new concepts are presented.  In Discrete trial teaching, a very small amount of information is given and the student’s response is immediately reinforced or not reinforced.  This is different compared with more traditional teaching methods which present large amounts of information with no clearly targeted interactive response on the student’s part.”(Autism Treatment Info http://www.autismtreatment.info/what+is+a+discrete+trial.aspx)

DSM-IV Diagnostic and Statistical Manual of Mental Disorders Published by the American Psychiatric Association used to define all mental health disorders for children and adults also listing known causes of disorders, statistical incidence, prognosis and research regarding treatment approaches.   The most recently published edition of this manual is the 4th edition.  Other areas of the world use the, International Statistical Classification of Diseases and Related Health Problems, ICD- 1

Developmental, Individual-Difference, Relationship-Based (DIR) also known as DIR/Floortime:    “A model of addressing a child’s developmental challenges through relationship and affect, focusing on the child’s individual differences, and developmental levels (a child’s ability to stay engaged, express mutual pleasure and attention, to engage in complex problem solving and symbolic play, and to link ideas). The cornerstone of the D.I.R. model is “floor time.”” (The Interdisciplinary Council on Developmental and Learning Disorders http://www.icdl.com/dirFloortime/overview/index.shtml)

Differential Diagnosis:  A process of arriving at a diagnosis by assessing the person’s symptoms and systematically considering all possible alternative explanations until the most likely cause or diagnosis is identified.

Di-methylglycine (DMG):  Dimethylglycine or DMG is a non-protein amino acid found naturally in animal and plant cells.  Research on humans and laboratory animals has shown that DMG strengthens the immune system. The immune system is dysfunctional in many individuals with autism. Some children and adults with autism have seizures, and there are two published reports of decreases in seizure activity as a result of DMG (New England Journal of Medicine, 1982, 307, 1081-1082; Epilepsia, 1989, 30, 90-93).  Considered to be controversial – see www.quackwatch.org

Dopamine:  A chemical transmitter in the brain similar to adrenaline. Dopamine affects brain processes that control movement, emotional response, and ability to experience pleasure and pain.”(http://www.utexas.edu/research/asrec/dopamine.html) 

Down Syndrome:  Down syndrome is a naturally occurring chromosomal arrangement that has always been a part of the human condition. The occurrence of Down syndrome is universal across racial and gender lines, and it is present in approximately one in 800 births in Canada.

Down syndrome is not a disease, disorder, defect or medical condition. It is inappropriate and offensive to refer to people with Down syndrome as “afflicted with” or “suffering from” it. Down syndrome itself does not require either treatment or prevention.

The sole characteristic shared by all persons with Down syndrome is the presence of extra genetic material associated with the 21st chromosome. The effects of that extra genetic material vary greatly from individual to individual. Persons with Down syndrome karyotypes may be predisposed to certain illnesses and medical conditions, but that genetic arrangement does not guarantee their development. The same illnesses and conditions are also present in the general population. Timely and accurate diagnosis and appropriate treatment of these illnesses and conditions improves both the length and quality of life, to the same extent as would be expected in the population without Down syndrome. Vigilance on the part of health care practitioners is required to identify and treat any of them if they arise.”(Canadian Down Syndrome Society http://www.cdss.ca/)

Echolalia:
  “repeating words or phrases heard previously. The echoing may occur immediately after hearing the word or phrase, or much later. Delayed echolalia can occur days or weeks after hearing the word or phrase.”(Canadian Autism Intervention Network http://www.cairn-site.com/en/glossary/glossary.html)

EEG “Electroencephalogram”:  A medical procedure where electrodes are placed on areas on a patient’s head to record brainwaves. It is used to identify seizures.

Engagement
:  A process in which “Children coo, smile, and gesture with their partners. Building intimacy, joy, and a rhythm to interactions. The foundation for more purposeful interactions and learning.” (http://www.monarchschool.org/ParentsGlossary.html#EI)

Environmental Engineering: Environmental engineering is a formal term for the process of arranging the physical environment to enhance learning and behaviour. The physical environment of a setting serves as a complex set of stimuli that may significantly influence appropriate or inappropriate behaviours. Instructors/ consultants can positively affect a person’s performance by paying careful attention to such factors as the basic layout of space, wall displays, traffic patterns, and other more subtle aspects of the physical environment.

Epidemiology: This is the study of how a disease affects a population. For example, an epidemiologist might study how prevalent the disease or condition is and how this changes over time, how it is distributed geographically or across age or social groups, etc.

Epilepsy:  “Epilepsy is not a disease or a psychological disorder, but rather a seizure disorder caused by sudden bursts of electrical energy in the brain.”((Epilepsy Ontario http://www.epilepsyontario.org/
Recent studies suggest that about 7.6% of children with autism had developed epilepsy, and 5% of children had “autistic” features. Furthermore, approximately 25-30% may develop seizures at some point in life.” (Epilepsy Ontario (http://epilepsyontario.org/client/EO/EOWeb.nsf/
b88276df9b41610b85256e5900752659/2331de347d2923fc85256d4e00661d31?OpenDocument&Highlight=2,autism
)

Etiology:  The study of the causes or origins of a disease.

Executive Functioning:  ”executive function refers to the cognitive skills that are used to solve a problem:

  • - representing the problem
  • - making a plan to solve the problem
  • - executing the plan
  • - evaluating the effects of the plan

For example, they may know rules and be able to repeat them, but nonetheless have considerable difficulty putting them into practice. They may also exhibit problem behaviours such as physical aggression.

In many cases, difficulties with executive function may be even greater than one would expect based on a child’s overall developmental level, as represented, for example, by performance on an IQ test. This can be quite frustrating for parents and caregivers, who may expect more from a child, given his or her intelligence, than he or she is able to provide.” What happens when the development of executive function goes awry? Philip David Zelzo, Ph.D. www.aboutkidshealth.ca/ofhc/news/SREF/4439.asp

Expressive Language:   “
Learning to Speak, and to Use Language” ((www.speech-language-therapy.com/devel2.htm)

Extinction:  This is a technical term in behavioural psychology, referring to the withholding of reinforcement for a behaviour that has previously been reinforced, in order to eliminate the behaviour. The word “extinction” may also refer to the reduction in the frequency of occurrence of the behaviour that results from withholding reinforcement.

Facilitated Communication: 
The use of a keyboard by a person with autism. The training begins with simple questions that have predictable answers, and becomes increasingly complex with less physical support from the facilitator. Proponents of this method argued that some people with autism eventually learn to communicate complicated thoughts. It has now been discredited through stringent research.” (Canadian Autism Intervention Research Network http://www.cairn-site.com/en/glossary/glossary.html)

Family Centered/Focus Model:    Family centered services emphasize the family’s identification of their needs, resources and service requirements. http://www.childcareaware.org/en/tools/glossary/?filter=F

Floortime:  see Developmental, Individual-Difference, Relationship-Based (DIR) also known as DIR/Floortime 

Fluency training: “Is used within other programs to maximize generalization and retention of learned language skills. Fluency techniques can result in increased accuracy and speed of performing speech tasks.”(Autism Society of Canada www.autismsocietycanada.ca/approaches_to_treatment/communication_systems/index_e.html)

Fragile X Syndrome:  “The most common cause of inherited mental retardation, with an incidence of about 1/1500 in males and 1/2500 in females. The inheritance pattern of the disease is unlike other X-linked disorders, because it shows significant numbers of apparently unaffected male carriers and some clinically affected females. The disease derives its name from the presence of a fragile site on the X chromosome of affected individuals.”(Autism-Resources.com www.autism-resources.com/autismfaq-simi.html)

Functional Analysis:   “A functional behavioral analysis begins as an assessment, but includes the added step of systematically altering the antecedents to and consequences of the behavior to determine precisely which are the driving forces behind that behavior.” http://www.polyxo.com/fba/  In other words, a behavioural assessment identifies the probable causes of a behavior. A functional analysis includes an “experiment” to confirm the causes.

Functional Behaviour Assessment:  A functional behavioural assessment is a systematic process to obtain a precise description of a behaviour and the factors that influence it. This usually includes a measure of the frequency of occurrence of the behaviour, information about the context in which it occurs, and information about the consequences or other factors that maintain or influence it.  The goal is the identify the purpose or function of a person’s behaviour(s); to develop and implement a plan to modify variables that maintain problem behaviours; and to teach appropriate behaviours using positive interventions.

Functional MRI:  “A type of magnetic resonant imaging (MRI) scanning in which scientists can see what parts of the brain are active while a subject is performing a task, such as solving a math problem in the MRI scanner. “(Canadian Autism Intervention Research Network http://www.cairn-site.com/en/glossary/glossary.html)

Gene:
Originally defined as the physical unit of heredity, it is probably best defined as the unit of inheritance that occupies a specific locus on a chromosome, the existence of which can be confirmed by the occurrence of different allelic forms. Genes are formed from DNA, carried on the chromosomes and are responsible for the inherited characteristics that distinguish one individual from another. Each human individual has an estimated 100,000 separate genes.”
(Canadian Autism Intervention Research Network
http://www.cairn-site.com/en/glossary/glossary.html) )

Generalization:  There are two types of generalization: “Stimulus Generalization” and “Response Generalization”.

Stimulus Generalization refers to the application of a skill or behaviour learned in one situation to another different but similar situation. Once the skill is acquired, the child begins to demonstrate the skill with a new person (with Dad, although Mom was the teacher), in a new environment (at school, after the skill was learned at home), or in response to different stimuli or cues (identifying real trucks and cars, after being taught to identify pictures of trucks and cars).

Response Generalization occurs when a person produces behaviours that are different from but similar to the behaviours that have been taught (e.g. a child spontaneously begins to greet people with “Hi, I’m Justin” after being taught to say “Hi, my name is Justin”). Response generalization can also occur with strategies to reduce behaviours. For example, a program might target the behaviour of hitting, and as this is reduced other behaviors such as pushing and kicking may also decline.

Gentle Teaching:  This is a totally non-aversive therapy emphasizing bonding between teacher and student. Developed by John McGee, he contends that persons who persistently hit, bite, kick, scratch, self-stimulate, or withdraw have not bonded with their caregivers and that teachers must help move behaviourally-involved persons from a state of emotional distancing to one of meaningful human engagement so that they will find it unnecessary to express their needs through primitive or harmful responses.”  Research does not support this therapy as making discernable improvements in student behaviour.((Autism Society of PEI http://www.autismsociety.pe.ca/Home/autism-glossary) (National Center for Biotechnology Behavior www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9631207&dopt=Abstract)

Generalized (or global) Anxiety Disorder:  This disorder is characterized by excessive, prolonged worry and tension about everyday things like work, one’s health, or family and friends.

Gestalt:  A “Gestalt” is a unified whole that is more than just the sum of its parts.  Gestalt language processing refers to learning entire phrases or other language chunks as whole units, versus learning all of the individual words within a chunk and combining them in unique and flexible ways.  See also scripting.

Gestalt Learner:  Many children with autism are “gestalt learners” of language in that they tend to remember and use entire phrases as “chunks” or whole units.

Global Delay: A delay in development across the whole spectrum of abilities, including, cognitive, motor, and language abilities.

Gluten-free/Casein-free Diet (GF/CF) Diet:  A diet believed by some to help improve the symptoms of autism. It involves elimination from the diet of gluten (a protein found in wheat and other grains) and casein (a protein found in milk). It is believed, although not proven, that the undigested portion of these proteins acts likes a chemical in the brain producing symptoms in children with autism. Gluten is found mainly in wheat, oats and barley; casein in milk products. Certain people on the autistic spectrum have found that a diet free from these things can help their concentration and prevent digestive problems.

Gold standard:  A tool or a practice that is considered to be of the highest standard at the time.

IQ (Intelligence Quotient):  Now an out-dated term referring to a person’s cognitive ability or level of intelligence, as measured by a standardized test. An intelligence quotient is based on a ratio between a person’s “mental age” and “chronological age” but modern intelligence tests no longer calculate intelligence scores in this manner. Standardized tests compare a person’s performance to performance of many other people of the same age completing the same tests.

Non-Verbal Communication: Any form of communication that does not involve the use of spoken language.  For example, gestures, facial expressions and eye contact, are non-verbal forms of communication.

Nonverbal Learning Disorder: Nonverbal Learning Disorder (NLD) (also known as NVLD) “a nonverbal learning disability describes a situation in which the underlying cause of a student’s learning difficulties is believed to be a generalized weakness in the ability to cognitively process nonverbal information. Typically, such a student performs quite well verbally (both receptively or “listening” and expressively or “speaking”) but struggles to understand or remember information which is presented visually. This is not due to poor vision but is related to an assumed weakness in the brain’s ability to fully or efficiently process nonverbal information.” (www.hopkins.k12.mn.us/Pages/North/LD_Research/definitions_frame.htm)

This term is used when a person shows some autistic symptoms, but does not fully meet the diagnostic criteria for any of the other four diagnostic categories. The Pervasive Developmental Disorders (also known as Autistic Spectrum Disorders) are all “neurological disorders of unknown cause. The symptoms include diminished ability to understand language and to communicate with and to interact with others. Children with a PDD usually have limited interests and engage in repetitive activities. There may be sensory problems related to perception of sound (hypersensitivity or lowered response)”(Canadian Autism Intervention Network http://www.cairn-site.com/en/glossary/glossary.html)

Pervasive Developmental Disorder, not otherwise specified (PDD-NOS):  “The diagnosis of PDD-NOS is used when there is severe impairment in social interaction and verbal and nonverbal communication skills, or when stereotyped behaviour, interests and activities are present, but symptoms do not meet the criteria for other autistic disorders.” (Canadian Autism Intervention Network  www.cairn-site.com/glossary/glossary.html#P)

Physical Therapy (PT):   A treatment of physical disabilities given by a trained physical therapist that includes the use of massage, exercise, etc., to remediate mobility and gait and to modify strength, balance, tone, and posture and help the person improve the use of bones, muscles, joints, and nerves.

Pioneered by Andrew Bondy and Lori Frost of the Delaware Autistic Program. Considered a kind of augmentative communication.”(www.autism-resources.com/autismfaq-educ.html)

Pivotal Response Training:  “PRT is a naturalistic behavioural intervention developed by Robert L. Koegel and Laura Schreibman at the University of California in Santa Barbara. Pivotal Response Training (PRT) is a behavioural treatment intervention based on the principles of applied behaviour analysis (ABA). PRT aims to increase the generalization of new skills by increasing motivation, including components such as child choice, turn-taking, reinforcing attempts and interspersing maintenance tasks. PRT has been used to develop language skills, play skills and social behaviours in children with autism.” 
(www.autismsocietycanada.ca/approaches_to_treatment/other_methods/index_e.html)

Positive Behaviour Support (PBS)  Unlike traditional behavioral management, which views the individual as the problem and seeks to “fix” him or her by quickly eliminating the challenging behavior, positive behavioral support (PBS) and functional analysis (FA) view systems, settings, and lack of skill as parts of the “problem” and work to change those. As such, these approaches are characterized as long-term strategies to reduce inappropriate behavior, teach more appropriate behavior, and provide contextual supports necessary for successful outcomes.

PBS and FA can help practitioners and parents understand why the challenging behavior occurs—its function or purpose for the individual. In addition to helping practitioners and families understand the individual with the challenging behavior, PBS and FA also help them understand the physical and social contexts of the behavior. Moreover, PBS and FA provide a framework for helping the child to change challenging behaviors. (http://en.wikipedia.org/wiki/Positive_behavior_support)

They often have particular problems in understanding abstract words and concepts or figures of speech, and getting the “main idea” in a sentence or conversation. They may have problems with turn-taking in conversations, reading the non-verbal cues of their conversational partners, or maintaining a topic or changing topics appropriately. There is some debate about whether Semantic-Pragmatic Language Disorders are part of the Autistic Spectrum or purely disorders of communication.

Sensory Defensiveness:  “a condition in which an individual is extremely sensitive to light touch. Theoretically, when the tactile system is immature and working improperly, abnormal neural signals are sent to the cortex in the brain which can interfere with other brain processes. This, in turn, causes the brain to be overly stimulated and may lead to excessive brain activity, which can neither be turned off nor organized. This type of over-stimulation in the brain can make it difficult for an individual to organize one’s behavior and concentrate and may lead to a negative emotional response to touch sensations.” (http://wasweb.franklinlakes.k12.nj.us/teachers/rbernstein/OT/sensory_integration?textonly=)

Sensory Modulation:   “[W]hen the senses work together. Each sense works with the others to form a composite picture of who we are physically, where we are, and what is going on around us. Sensory modulation is a neurological function that is responsible for producing this composite picture. It is the organization of sensory information for on-going use. (Coping.org http://coping.org/intervention/sensory/sensorymod.htm#modulation))

Sensory Processing: can refer to specific tests of sensory processing, observations of a child’s sensory function, or the updated diagnostic label of “Sensory Processing Disorder” which includes a wider range of children and adults then those diagnosed with ASD.

Shared Attention and Meaning:  Also called Joint Attention Child and play partner are both focused on the same theme, object, and/or idea.

Social Stories:  Social Stories were developed in 1991 by Carol Gray as a tool for teaching social skills to children with ASD. They focus on developing the ability to recognize the feelings, points of view or plans of others. Stories are developed to meet the child’s individual needs based on their anxieties, their fears or the difficulty of particular situations. The stories help the child to develop appropriate responses to real life situations.” (Autism Society of Canada  www.autismsocietycanada.ca/approaches_to_treatment/other_methods/index_e.html)

Tactile Dysfunction: 
Dysfunction in “the tactile system can be seen in withdrawing when being touched, refusing to eat certain ‘textured’ foods and/or to wear certain types of clothing, complaining about having one’s hair or face washed, avoiding getting one’s hands dirty (i.e., glue, sand, mud, finger-paint), and using one’s finger tips rather than whole hands to manipulate objects. A dysfunctional tactile system may lead to a misperception of touch and/or pain (hyper- or hyposensitive) and may lead to self-imposed isolation, general irritability, distractibility, and hyperactivity.” ((http://wasweb.franklinlakes.k12.nj.us/teachers/rbernstein/OT/sensory_integration?textonly=)

Tactile Defensiveness:  Is a condition in which an individual is extremely sensitive to light touch. Theoretically, when the tactile system is immature and working improperly, abnormal neural signals are sent to the cortex in the brain which can interfere with other brain processes.

The vestibular system refers to structures within the inner ear (the semi-circular canals) that detect movement and changes in the position of the head…Some children may be hypersensitive to vestibular stimulation and have fearful reactions to ordinary movement activities (e.g., swings, slides, ramps, inclines)… As a result, they seem fearful in space. In general, these children appear clumsy. On the other extreme, the child may actively seek very intense sensory experiences such as excessive body whirling, jumping, and/or spinning. This type of child demonstrates signs of a hypo-reactive vestibular system; that is, they are trying continuously to stimulate their vestibular systems.”(Canadian Autism Intervention Research Network http://www.cairn-site.com/en/glossary/glossary.html)

Visual Processing:   Taking visual information from the environment, accurately interpreting the visual information, and using the information to make decisions for ideas and actions. Issues of visual processing are many and varied, and require a very specific diagnosis. The ability to organize visual information and use it for performance in the environment (e.g., when throwing a softball to a friend, know how far away the friend is and how hard and how far to throw the ball).

Visio-Spatial Skills: These are cognitive abilities that relate to the way you perceive the objects and surroundings of your environment.

Weighted Vest:
The concept of the weighted vest is based on the technique of deep pressure. Deep pressure is used to assist the child to self-calm and relax so that sensory stimulus can be processed. The use of a weighted vest is thought to provide the child with unconscious information from the muscles and joints. Children who are easily distracted, hyperactive and lacking in concentration are said to respond positively to the additional weight a vest provides.”

The Wilbarger Protocol: “Some children have a tendency to respond to certain harmless sensations as if they were dangerous or painful. This is called sensory defensiveness (SD). The child with SD may misperceive the world as dangerous, alarming or at the very least irritating. When left untreated, SD can have a negative influence on every aspect of life. The protocol uses frequent application of firm/deep pressure touch input to various parts of the body. This is followed by gentle joint compression.”(Autism Society of Canada www.autismsocietycanada.ca/approaches_to_treatment/sensory_integration_therapies/index_e.html)

Wechsler Intelligence Scale for Children (WISC-III):

”an individually administered clinical instrument for assessing the intellectual functioning of children.”(Canadian Autism Intervention Research Network http://www.cairn-site.com/en/glossary/glossary.html)

Wechsler Preschool and Primary Scale of Intelligence – Revised (WPPSI-R):

”a clinical instrument similar to the WISC-III and the WAIS-R, except for children ages 3-0 to 7-0.”(Canadian Autism Intervention Research Network http://www.cairn-site.com/en/glossary/glossary.html)
