6/12- Cognitive Development Flashcards
Current views on intelligence:
- Multifaceted and ______ organized
- Some ______ impacts global functioning on cognitive tasks as well as special abilities
- A person’s __ is a general estimate of the sum of many different abilities
Current views on intelligence:
- Multifaceted and hierarchically organized
- Some general factor (g) impacts global functioning on cognitive tasks as well as special abilities
- A person’s IQ is a general estimate of the sum of many different abilities
T/F: the max IQ score is 100
False; 100 is the average IQ
Normal curve characteristics:
__% of population with scores within __ standard deviations of the mean ()
__ of the population have IQ scores within 1 SD of the mean ()
Normal curve characteristics:
- 95% of population with scores withNextin 2 standard deviations of the mean (70-130)
- 2/3 of the population have IQ scores within 1 SD of the mean (85-115)
What is intellectual giftedness (“superior” range)?
Starts 2 SDs above the mean (> 130)
(Mental retardation less than 2 SDs below)
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.
What are the Wechsler Scales?
What are some nonverbal measures?
Wechsler Nonverbal Scale of Ability (WNV)
- Ages 4 yrs - 21 yrs 11 mo
Test of nonverbal intelligence- 3rd ed
- Ages 5-85
Universal Nonverbal Intelligence Test (UNIT)
- Ages 5 - 17 rs 11 mo
Additional Assessments
What is Stanford-Binet Intelligence Scale good for?
- Ages 2-5
- Good for assessing low end and very high end of intellectual functioning range
What is Woodcock-Johnson II tests of Cognitive used for?
- Ages 2-90+
- Used most often by school districts
What is Kaufman Brief Intelligence Test used for?
- Ages 4-90
- A quick measure of verbal and nonverbal intelligence
What are the Differential Ability Scales used for?
- Ages 2.5 yrs - 17 yrs 11 mo
- More culturally unbiased measure
- Good for assessing African American, Asian, Hispanic, and non-White/Non-Hispanic children equally
What are causes/risk factors for mental retardation/intellectual disability: Biomedical?
Bomedical:
- Chromosomal/genetic disorders: Down’s, William’s, Fragile X, Prader-WIlli
- Maternal risk factors: age, illness
- Premature birth or birth injury
- Traumatic brain injury
- Degenerative disorders
- Seizure disorders
What are causes/risk factors for mental retardation/intellectual disability: Social?
Social:
- Poverty
- Domestic violence
- Lack of prenatal care
- Traumatic exposure: neglect, poverty, impaired caregivers
What are causes/risk factors for mental retardation/intellectual disability: Behavioral?
Behavioral:
- Parental drug, alcohol, tobacco use
- Parental rejection or abandonment
- Trauma: abuse, neglect, domestic violence, danger
What are causes/risk factors for mental retardation/intellectual disability: Educational?
Educational:
- Parental cognitive disability
- Lack of medical referrals for intervention
- Impaired parenting
- Inadequate special education/early intervention
Characteristics/Diagnosis of Mental Retardation/Intellectual Disability in DSM5?
- Deficits in intellectual functions (e.g. problem-solving, planning, learning, etc.); generally full scale IQ < 70 (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)
What are some of the adaptive behavior skill areas (2 required with deficits in intellectual functions for Dx of intellectual disability)?
- Communication
- Self-care
- Home-living
- Social/interpersonal skills
- Use of community resources
- Self-direction
- Functional academic skills
- Work
- Leisure
- Health
- Safety
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
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
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
Level of severity: Severe?
- Little or no communication skills;
- Sensory impairments
- Need extensive supports throughout life in most domains
Level of severity: Profound?
- Minimal functioning; limited understanding of others/world
- No independence; usually need supervision and nursing care
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
