- Executive function and working memory
- Reaction time
- Brain volume
- Thinning of the cerebral cortex during adolescents
- Structural measures of connectivity
- Less brain activation (more efficient)
ACE components for reading and math skills:
C: 0.3
E: 0.2
Division general cognitive disability
- Mild general cognitive disability: 50 - 70
- Moderate general cognitive disability 35 - 50
- Severe general cognitive disability 20 - 35
- Profound general cognitive disability < 20
Which form doesn't has familial resemblance? (cognitive disability)
Characteristics males with FRX
- IQ declines after childhood
- Large, protruding ears
- Long face with prominent jaw
- Unusual behavior
Characteristics of Rett Syndrome (RS)
- Males do not survive it because it is on the X chromosome
- Happens to 1 in 10.000 females
- First year: normal development
- Regression occurs between 1 and 4 years.
- Problemens with language, coordination and repetitive movements
Cause Rett syndrome (RS)
Definition duchenne muscular dystrophy (DMD) and effect on IQ
Definition Lesch-Nyhan syndrome and effect on IQ
Definition neurofibromatosis type 1 (NF1) and effects on IQ.
What is the most important cause of general cognitive disability ?

- Increased neck tissue
- Muscle weakness
- Speckled iris of the eye
- Open mouth
- Protruding tongue

Where leads an extra y chromosome to?
Defintion Angelman syndrome
- Moderate cognitive disability
- Abnormal gait
- Speech impairment
- Seizures

Affect of additive genetic variance on parent-offspring study
Affect of additive genetic variance on twin model
Affect of additive genetic variance on GWAS
Disadvantage candidate gene approach
What is the difference between achievement and ability?
ability: based on genetic influence
What is the generalist genes hypothesis?
1. Genes that affect common learning disabilities are largely the same genes responsible for normal variation in learning abilities
2. Genes that affect one learning disability are also likely to affect other learning disabilities
Which 3 genetic findings are special for cognitive abilities?
2. Assortative mating is substantial
3. The same genes affect diverse cognitive and learning abilities
How is it possible that heritability increases during development?
What is an exception of heritability increasing during development?
What is assortative mating?
What is the major strategy for finding genes associated with cognitive abilities and the genetic correlations among them?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
