Midterm 2 Flashcards
What is the Flynn Effect?
Secular increase in average scores on measures of inelligence
Why does the Flynn Effect Happen?
Likely a combination of factors
- Improved nutrition
- Better education
- Greater environmental complexity
- Increased test taking skills
-
Why is the Flynn Effect important?
Interpretive Problems:
- Administrator must use test norms cautiously and appropriately
Implications for psychologists, researchers and law:
- implementing educational interventions
- identify intellectual disabilities for capital offences
- empirical research may have to make decisions about whether to use the same test throughout a longitudinal study (10+ years) or have score comparison issues
What does the Flynn Effect imply?
- likely to attain higher score on early version of IQ test
- overestimate individual’s IQ by about 0.3 points per year between the year it was normed and the year the test was administered
- high stakes decisions where IQ cut-off is necessary (e.g. intellectual disability diagnoses for capital punishment, IQ=70)
- figures to access to services and accommodations
What is the definition of an intellectual disability?
The presence of significant limitations in intellectual functioning and adaptive behaviour prior to age 10.
An IQ score less than or equal to 70 is a common indicator of significant limitation in intellectual functioning
What are the 5 “special findings” of genes and intelligence research?
- Heritability of intelligence increases from about 20% in infancy to possibly 80% in later adulthood
- Intelligence captures genetic effects on diverse cognitive and learning abilities
- Assortative mating greater for intelligence
- Intelligence is normally distributed
- Intelligence is associated with education (and social class)
What are the three laws of the Genetics of Complex Traits?
- All traits show significant genetic influence
- No traits are 100% heritable
- Heritability is caused by many genes of small effect
Why is intelligence important? (not why is it important to be smart but what does intelligence importantly contribute to)
- one of the most stable behavioural traits
Correlation of 0.63 when tested at age 11 vs age 79 - one of the best predictors of social outcomes
- Health implications
What are the 5 rules of intelligence?
Heritability of intelligence increases from about 20% in infancy to possibly 80% in later adulthood
General genetic effects across diverse cognitive and learning abilities
Assortative mating is greater for intelligence than for other traits (0.40 for intelligence)
Positive genetics: the genetics of high intelligence
Intelligence brings some genetics to social epidemiology
What is the Range of Reaction Theory?
Each person responds to the environment in a unique way based on their genetic makeup
Reaching full potential is dependent upon environmental stimulation you experience in childhood
Those born with average genetic potential but in a stimulating environment will have environmental contributions to their intelligence
What are Arthur Jensen’s two levels of abilities
Level I: Rote memorisation (remained consistent among human race)
Level II: Conceptual and analytical abilities
What are learning disabilities:
Cognitive disorders that affect different areas of cognition, particularly language or reading
These are not the same as intellectual disabilities
Often affect children with average to above-average intelligence and is comorbid with other disorders like ADHD
What is dysgraphia?
Struggle to write legibly (the physical task of writing with a pen and paper is extremely challenging)
Inconsistent with a person’s IQ
Requires academic accommodations
What is dyslexia?
Most common learning disability in children
Inability to correctly process letters
Neurological mechanisms for sound processing does not work properly in someone with dyslexia
How is success defined in the field of intelligence?
Doing or achieving something that is generally considered desirable in the society
Success in one field may restrict you from having success in another field
Some highly intelligent people excel and others done
