Intelligence Flashcards
Plomin and Spinath (2004)
found that heritability in intelligence increases throughout the life span and that some genes affect diverse cognitive abilities
this shows the significant affect of genes on intelligence and the fact that it affects cognitive abilities too serves to highlight the complexity of its heritability
Plomin and VonStrumm (2018)
used a Genome Wide Association Study (GWAS) to study genes and intelligence on a much larger scale. The study aimed to identify loci throughout the genome that are associated with individual differences in intelligence. A key finding of the study indicated that intelligence is highly polygenic which indicates how many genes have a small affect acting in concert
It’s large scale nature aids validity and reliability and the fact that it’s ‘polygenic’ shows that genes do play a large role in intelligence
Cho and Lin (2010)
they looked at the influence of family processes on motivation, belief, intelligence and creative problem solving. They studied 733 scientifically talented Korean students and found that across all students, perceived positive family processes indirectly predicted enhanced confidence in intelligence and intrinsic motivation
this highlights how family processes can have a significant impact on different areas of a child’s intelligence and is thus important
Ceci and Williams (1997)
ooojed at the relationship between schooling, intelligence and income and concluded that intelligence and schooling have a bidirectional relationship such that each variable influences variations in the other
In turn, schooling and intelligence have an effect on economic conditions which this signifies the overriding effect of environmental factors on intelligence
