What is intellectual giftedness ("superior" range)?

Starts 2 SDs above the mean (> 130)

(Mental retardation less than 2 SDs below)

5

What is the Flynn Effect?

- When a new version of an IQ test is normed, the standard scoring is set so that performance at the population median results in a score of IQ 100

- If test-takers are scored by a constant standard scoring rule, IQ test scores have been rising at an average rate of around three IQ points per decade.

17

Characteristics/Diagnosis of Mental Retardation/Intellectual Disability in DSM5?

- Deficits in intellectual functions (e.g. problem-solving, planning, learning, etc.); generally full scale IQ (not enough alone!)

- Accompanied by significant limitations in adaptive functioning in at least 2 of the adaptive skill areas

- Onset prior to age 18- must have evidence of deficits in childhood and adolescence (unless talking about a traumatic brain injury)

18

What are some of the adaptive behavior skill areas (2 required with deficits in intellectual functions for Dx of intellectual disability)?

- Social/interpersonal skills

- Use of community resources

- Self-direction

- Functional academic skills

- Work

19

Levels of severity of Mental Retardation/Intellectual Disability? How determined?

(formerly based on range of IQ scores)

Now by level of adaptive functioning:

- Mild

- Moderate

- Severe

- Profound

20

Level of severity: Mild?

- There may be no obvious differences in young children

- Differences often appear in academic settings for children and teens

- May be able to have a job with special training and supervision and may be able to live partially independently

21

Level of severity: Moderate?

- Skills lag behind same-age peers throughout development

- May need help acquiring basic skills for daily living (e.g. hygiene, safety, household chore)

-- may need supervised housing

- May work in sheltered environment or with extensive support and supervision

22

Level of severity: Severe?

- Little or no communication skills;

- Sensory impairments

- Need extensive supports throughout life in most domains

23

Level of severity: Profound?

- Minimal functioning; limited understanding of others/world

- No independence; usually need supervision and nursing care

24

How does American Association on Intellectual and Developmental Disabilities (AAIDD) classify Mental Retardation/Intellectual Disability? (and 5 assumptions)

Significant limitations both in intellectual functioning and adaptive behavior as expressed in conceptual, social, and practical skills which are apparent prior to the age of 18;

Definition applied within context based on 5 assumptions:

1. Limitations are considered within the context of the person’s environment and culture

2. Assessment should consider cultural and linguistic diversity as well as differences in communications, sensory, motor, and behavioral factors

3. Limitations often coexist with strengths

4. You must develop a profile of needed supports

5. With appropriate personalized supports, the functioning of the person with the intellectual disability will generally improve

25

How is academic achievement affected by learning disabilities?

- Individual's achievement on individually administered standardized tests of academic performance are substantially below (2 SDs) that are expected for age, schooling, and level of intelligence

- Smaller discrepency (between 1-2 SDs) between IQ and achievement can also be used especially if IQ performance may have been compromised by a comorbid disorder, medical condition, or other factor

26

What are some assessments for academic achievement and learning disabilities?

- Woodcock-Johnson IV Tests of Achievement

- Wechsler Individual Achievement Test- II ed

- Wide Range Achievement Test- 4th ed

27

What is the Individuals with Disabilities Education Act (IDEA)? Problems?

Federal law that requires school districts to provide a free and appropriate education to students with disabilities

- Not based on discrepancy model of DSM

- Based on "educational need"

(School use Response to Intervention (RTI) method to determine if the student has received high quality instruction prior to a label of "learning disability")

28

What does Section 504 of the Rehabilitation Act of 1973 say?

Specifies that no program that receives federal money can discriminate against a person with a disability

- Requires that students have an equal opportunity to participate in all school activities

- Some children who do not qualify for Special Education under IDEA may still receive accommodations and modifications under Section 504

29

Populations encompassed by IDEA and Section 504?

IDEA children are a smaller subset of 504 children
