Nature vs Nurture Flashcards
Nature
Genetics, hereditary factors
Nurture
The environment; education, tutoring, encouraging work environment
Intelligence
The global capacity to act purposefully, to think rationally and to deal effectively with the environment.
IQ
Intelligence Quotient. Deteced by dividing mental age by physical and X 100

Findings; Scarr
- Link b/w personality(extraversion/introversion) and IQ, due to hereditary rather than hereditary determining IQ directly.
- Study conducted on black children being adopted by white adults and looking at IQ against black children raised by their own parents. Data from both families suggest that hereditary plays a large role, as differences in IQ from adopted and non-adopted children were minimal.
Findings; Bouchard
• Found sets of twins from around the world that had been separated in infancy and raised apart.
• Brought them to a lab; compared to them on:
-Ability
-Personality
-Leisure time
-Vocational interests
-Social attitudes
• Results; Identical twins raised apart, still had similarities.
• IQ still fairly similar raised apart, more than fraternal.
• Heredity makes a relatively strong link to IQ scores.
Findings; Daniel/pulman
• Tested socialabiity vs. shyness of children, adopted at 12 and 24 months.
• Test to see if more like biological/adoptive mums.
• Result^^^: found heredity plays a role in shyness and the environment does too.
-Extreme shyness from biological mum; child shy at 2 years.
-Extreme shyness from adoptive parent: child shy at 2 years.
Evaluation study
Combine evidence from both hereditary and environment and establish the interaction b/w the two , influecing intelligence.
Evaluation study findings
→’Another study’…:
• Investigators followed children of 2 groups of mothers, high IQ and low IQ children.
• Those adopted at birth by parents of»_space;> average income, education.
• Intelligence tests taken during school years showed:
-Low IQ biologically increased -»> above avg. In IQ due to environment.
-High IQ biologically increased -»> very high above average due to environment.
• Heredity and environment important to development. (both have influences)

Research: suggests that children adopted from orphanages have a greater ability to progress Intellectually, due to the enriched environment, compared to a relatively deprived orphanage evironment. Effects most drastic on
