What experiments did Galton do?
Studied twins - to see how similar they were, especially in levels of intellect
- Looked at their behavioural similarities/ differences
He found: The closer the relative, the more similar you are
He argued that you can promote intelligence through selective breeding
What are the 3 Methods of investigating the heritability of intelligence?
Outline family studies as a method of investigating the heritability of intelligence
X- However, families are usually in the same environment, so it is hard to distinguish nature and nurture
Outline Plomin et al (2004)
% - Mz concordances
What did Plomins results show about intelligence
if intelligence was entirely the cause, Mz twins should have the same levels, but they dont
- this shows that the environment does have an influence on intelligence
However, Mz twins had better concordance than siblings
- so genetics clearly influences intelligence too
What are typical estimates of IQ heritability in the literature
Ranges from 50-80%
- of characteristics caused by genetics
What can explain the Variance in estimates of heritability?
AGE
What did Haworth et al (2010) say?
Genetics gets more important for your IQ as you age
- across childhood, adolescence and young adulthood
What are the 3 general concerns with studies into the heritability of intelligence?
Define assortative mating
A tendency to mate with those who are similar to ourselves
Outline Watson et al (2004) study into assortative mating
Outline perinatal nutrition as a factor of IQ
- Oddy et al (2004)
What were the 4 categories of environmental factors that influence IQ, outlined by Neisser et al (1996)
Outline prenatal substances exposure as a factor of IQ
- Mortensen et al (2005) - smoking
Fetal alcohol syndrome
Mortensen et al (2005) - found links between maternal smoking and IQ scores in 18 YEAR OLDS MALES!
outline prematurity and birth weight as a factor in IQ
- the more premature, and smaller weight, leads to risks surrounding IQ
What was Mayer & Saloveys (1990) concept of emotional intelligence
- dont worry too much about this one
KEY POINT:
- Some can process emotional information better than others, but this doesnt mean you have a high IQ or vice versa
What is a limitation of emotional competency as a concept?
Rigid - suggests you are either competent or incompetent
Define Alexithymia
What was Thorndikes (1920, 1937) early attempts at emotional intelligence
X - this was far too broad however
- and didnt specify emotional intelligence really, as E.I only includes emotional related information and emotional behaviours
Is emotional stuff an intelligence? or is it an ability?
- knowing what a person feels is a behavioural tendency, not an intelligence
Outline Mayer & Salovey’s theory of Emotional Intelligence
STRATEGIC:
EXPERIENTIAL:
What is recognising facial emotion linked to?
This has implications in:
• Depression, alcoholism, Sz, Autism, Eating Disorders etc
What are the 6 basic emotions?
Outline McClure et al (2003) study into the facial recognition in those with Bipolar
