Mrs. Elizabeth Keele

Course Content #1

• Explain in detail the American Association of Intellectual and Developmental Disabilities (AAIDD) definition of mental retardation.

What is the AAIDD?• Founded 1876• "Association of

Medical Officers of American Institutions for Idiotic and Feebleminded Persons"

Classification of MR 1910

• Moron– 7-12 years

• Imbecile– 2-7 years

• Idiot– < 2 years

THESE TERMS ARE NOW

INAPPROPRIATE AND OFFENSIVE

Name Change…

• Am. Assoc. of Mental Retardation– 1921

Name Change• 2007• American

Association of Intellectual and Developmental Disabilities

Current definition & Criteria

Definition:

• Mental Retardation

• Intellectual Disability

Is intellectual disability the same as mental retardation? A. YES

B. NO • “Intellectual disability” is the preferred term

Intellectual disability

• Name has changes not the definition…

Definition of Intellectual disability

• Intellectual disability is a disability characterized by significant limitations in both intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills. This disability originates before the age of 18.

Definition of Intellectual disability

• Intellectual functioning• AKA: intelligence• general mental capacity– Learning– Reasoning– Problem solving

Definition of Intellectual disability

• How can we measure intellectual functioning?• IQ test. • score <70 – 75 = limitation in intellectual

functioning.

Definition of Intellectual disability

• Intellectual disability is a disability characterized by significant limitations in both intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills. This disability originates before the age of 18.

Definition of Intellectual disability

• Adaptive behavior• Collection of conceptual, social, and practical

skills that are learned and performed by people in their everyday lives.

Definition of Intellectual disability

• Conceptual skills– Language & literacy– Money– Time– Number concepts– Self-direction

Definition of Intellectual disability

• Social skills– Interpersonal skills– Social responsibility– Self-esteem– Gullibility– Naïveté – Social problem solving– Ability to follow rules/obey

laws – Avoid being victimized

Definition of Intellectual disability

• Practical skills– activities of daily living – Occupational skills– Healthcare– Travel/transportation– Schedules/routines– Safety– Use money– Use telephone.

Definition of Intellectual disability

• Standardized tests can also determine limitations in adaptive behavior.

Definition of Intellectual disability

• Age of Onset–Before 18

• This condition is one of several developmental disabilities

Definition of Intellectual disability

• Assume – Limitations coexist with strengths– Level of functioning will improve – if appropriate personalized supports are

provided –over a sustained period

Definition of Intellectual disability

• Only on the basis of such many-sided evaluations can professionals determine whether an individual has intellectual disability and tailor individualized support plans.

Is intellectual disability the same as developmental disabilities?• "Developmental

Disabilities" is an umbrella term

• includes intellectual disability

• also includes other disabilities that are apparent during childhood.

Federal Definition of Developmental Disabilities

• According to the Developmental Disabilities Act, section 102(8), "the term 'developmental disability' means a severe, chronic disability of an individual 5 years of age or older that:

Federal Definition of Developmental Disabilities

• Severe, chronic disability 5 years+

1. Is attributable to a mental or physical impairment or combination of mental and physical impairments

Federal Definition of Developmental Disabilities

• Severe, chronic disability 5 years+ 1. Mental or physical impairment2. Is manifested before the individual attains age 22

Federal Definition of Developmental Disabilities

• Severe, chronic disability 5 years+ :1. Mental or physical impairment2. Is manifested before 223. Is likely to continue indefinitely

Federal Definition of Developmental Disabilities

• Severe, chronic disability 5 years+ :1. Mental or physical impairment2. Is manifested before 223. Is likely to continue indefinitely

4. Results in substantial functional limitations in three or more of the following areas of major life activity• Self-care• Receptive and expressive language;• Learning;• Mobility;• Self-direction;• Capacity for independent living; and• Economic self-sufficiency.

Federal Definition of Developmental Disabilities

• Functional limitations • Self-care• Receptive and expressive language;• Learning;• Mobility;• Self-direction;• Capacity for independent living; and• Economic self-sufficiency.

Federal Definition of Developmental Disabilities

• Severe, chronic disability 5 years+ :1. Mental or physical impairment2. Is manifested before 223. Is likely to continue indefinitely4. Results in substantial functional limitations (3+)5. Reflects the individual's need for services,

supports, or other assistance that is of lifelong or extended duration

Intellectual disability • Intellectual

disability encompasses the “cognitive” part of this definition

Is intellectual disability determined by just an IQ test?

A.YESB.NO

• 3 major criteria :– intellectual functioning, – adaptive behavior, – onset <18

IQ test• Tool • < 75 indicates a

limitation in intellectual functioning

History of Intellectual disabilities

• Earliest documentation– 1552 B.C. – Luxor, Egypt

Treatment throughout history

• Depended on customs– Eliminated– Amusement– Slavery

Skill based program

• Dr. Jean-Marc Itard– 1774-1838– Father of Special Ed.

Residential Facilities• First:– Abendberg– Johann Guggenbühl – 1841 – Switzerland

USA rehabilitation & reintegration

• Dorthea Dix– Asylums

• Samuel Howe– Director of Perkins

Institution for the Blind in Boston

• Hervey Wilbur – 1st private institution

Eugenics

• Sterilization laws

Small Group Questions• What is the AAIDD?• What is the definition of mental retardation?• ID originates before what age?• What is another term for intellectual functioning?• What are the skill-sets associated with adaptive behavior? (Give

specific examples of each skill set)• What is the relationship between developmental disability and

intellectual disability?• What is the federal government’s definition of developmental

disability?• Who are Johann Guggenbuhl, Dorothea Dix, Samuel Howe and

Hervey Wilbur in relationship to ID?• What are eugenics laws?

Course Content #2

• Detail the general deficits experienced by mental retarded individuals as compared with normal individuals in 3 distinct development stages– Infancy – early childhood– Childhood – adolescence– Late adolescence - adulthood

Cognitive Theory• Jean Piaget• Intellect &

develop thought processes

Cognitive theory3 Major Concepts

• Schema– Idea’s that grow from experience

• Assimilation– Ability to absorb new information into

schemas• Accommodation– Schemas change with new information

SENSORIMOTOR

• Age– Birth – 2 yrs

• Major developmental Task1) Mobility 2) Sense of self3) Object permanence4) Form mental images

Preoperational• Age–2 – 6 yrs

• Major developmental Task1) Express self with

language2) Understanding gestures3) Conservation

Concrete operational

• Age–6 - 12 yrs

• Major developmental Task1) Logical thinking2) Reversibility & spatiality3) Differentiate and classify4) Socializing 5) Apply rules

Formal operational

What does IQ stand for?

• Intelligence quotient–William Stern

• Median score –100 –95 % between 70 and 130

Is intellectual disability determined by just an IQ test?

• No!• 3 major criteria :– intellectual

functioning, – adaptive behavior, – onset <18

IQ test

• Tool • < 75 indicates a

limitation in intellectual functioning
