What is fluid intelligence?
The ability to solve abstract relational problems that have not been explicitly taught and are free from cultural influences
What is crystallised intelligence?
The ability to solve problems that depend on knowledge acquired in school of through other experiences
What groups are elemental abilities split into in structure of intellect theory?

Creative
The role of experience in mobilising cognitive mechanisms to meet environmental demands
What is the Flynn Effect?
the tendency of IQ scores to change over time and across generations
What contributes to the Flynn Effect?
- Nutrition
- Better/different education
- Different child rearing practices
- Technology - greater access to info
What is factorial invariance?
We would not expect predictive coefficients to change drastically across cohorts, even though the scores themselves might change
Why is IQ not everything?
- Self-discipline accounted for twice as much variance in final grades than IQ scores
- Self-discipline outdoes IQ in predicting academic performance of adolescents
What is a first degree relative?
Shares around 50% of genes e.g. parents and siblings
What is a second degree relative?
Share around 24% of genes e.g. grandparents, grandchildren, aunts etc
What is a third degree relative?
Shares around 12.5% of genes e.g. great-grandparents, great-aunt, first cousin etc
What did Francis Galton teach?
First to introduce the idea of nature vs nurture and heritability
What is genetic heritability?
The considering how much of any phenotype is passed on from parent to child.
How is genetic heritability assessed?
By considering the variability found between parents and child and considered in terms of the proportion of shared variance
What studies are used to assess genetic heritability?
- Family studies
- Twin Studies
- Adoption studies
How high is heritability of intelligence?
Estimates of 69-74%
What did Deary et al 2012 find about heritability estimates?
- there is genetic contribution to the stability of intelligence across the life span
- estimated to be only 38%
What 4 considerations do we need to keep in mind when considering the role of genes in the heritability of intelligence?
- Concepts of genetic heritability & environment
- Different types of genetic variance
- Assortative Mating
- Representativeness of twin + adoption studies
What are different types of genetic variance?
- Additive
- Dominant
- Epistatic
What is assortative mating?
Variation in traits between mating couples is not random - similar phenotypes or genotypes mate with each other
Why do we need to consider the representativeness of twin + adoption studies when considering genetic heritability?
they may under or over estimate heritability in the general populations
What environmental influences are there on intelligence? (4)
- Biological
- Family Environment
- School & Education
- Culture
How does biology influence intelligence?
- Nutrition
- Lead (-ve)
- Prenatal factors
How does family environment influence intelligence?
- Non-shared environments influence over shared
- Within family-factors considers how they influence trait behaviours that can complicate the genetic heritability route
- SES considered in terms of occupation
- birth order and family size
How does birth order and family size influence intelligence?
- As family size increases and birth order position increase, intelligence scores decreased
What is the admixture hypothesis?
- Influenced by SES and parental intelligence
- Lower IQ and SES tend to have more children
What is the resource dilution model?
- Parental resources are finite
- Family increases, resources for a single child decreases
What is the confluence model?
- Need to consider intelligence within the context of the family
- This intellectual environment is ever changing
How can culture influence intelligence?
- Decontextualisation
- Quantification
- Biologisation
What is decontextualisation?
The ability to disconnect from a situation, think about it abstractly and generalise from it
What is quantiifcation?
The ability to discover or express the quantity of something
What is culture biologisation?
- The prominance of biological and evolutionary theories over the last century
- Can give new insights but are concerned with millions of years of development
- study of ourselves is relatively new so should be careful
What 4 ideas does the Bell Curve propose?
1: The cognitive elite
2: Socioeconomic variables and IQ
3: The relationship between race and intelligence
4: The implications for social policy
Explain the cognitive elite
Suggests that there is an emergence of a CE within American based on the separation of society through college admission and the workplace
Explain socioeconomic variables and IQ
Suggests that an indvidivual’s intelligence is more important than SES for predicting enomic and social welfare
Explain the relationship between race and intelligence
Evidence fo higher IQ of asian-americans and lower IQ of african-americans in comparison to white americans
Explain the implications for social policy
- Population with lower IQ is increasing as women with lower IQ tend to have more children
- Immigrants also contribute towards this
What is eugenics?
A reproductive selection process within humans that aims to create children with desirable traits
What is positive eugenics?
Encouraging reproduction in those who are perceived to have superior traits
what is negative eugenics?
Discouraging or eliminating reproduction in those perceived to have poor hereditary traits
What is a Narrative Analysis Approach?
weighs up findings across studies by analysing whether each studies findings support or don’t support a hypothesis
What do we use to measure effect size?
Cohen’s d
What does effect size tell us?
How important a difference is
What did Lynn & Irwing find about sex differences in intelligence.
There is an effect size of men scoring higher than women even though it is small
What types of intelligence tests do men score better on?
Tests of spatial abilities
What types of intelligence tests do women score better on?
Tests of verbal ability
Can brain size account for biological difference in general intelligence?
- men’s brain are 10% larger
- only seen from adolescence onwards due to different rates of maturity
- link is small and overused as an explanation
Could differences in brain structure influence differences in intelligence?
- Females have a bigger splenium
- May mean tasks are more evenly distributed by hemispheres
What is the function of gray matter?
Processing information in the brain
What is the function of white matter?
Transports the information
Could differences in hormones account for sex differences in spatial ability?
Testosterone has been found to be related to higher performance in spatial ability tasks
Testosterone has an effect on organisation of spatial tasks
When did men need spatial tasks in the old days?
- Foraging and gathering food
- Engaging in warfare with others
- Maximising reproductive success
Where do preferences come from?
- Reinforcement
- Modelling
- Socialisation
What is test validity?
The extent to which a test accurately measures what it is supposed to measure.
What is internal reliability?
The different items within a test correlate positively with one another, suggesting they are measuring the same construct
What is test-retest reliability?
The reliability of a test over time. If the same person took an intelligence test at different points in time, you would expect the results to be similar
Why is it hard to measure internal validity of intelligence tests?
It depends on what you think intelligence is
Why is test validity important?
We need to make sure a test is measuring what we think it is otherwise we risk drawing false conclusions from it’s results. Particularly important if a test is going to be used to make decisions about people that will have a significant impact.
