INTELLIGENCE
Heredity of intelligence
-
study with twins
correlation high to low: Identical-tgt, identical-apart, frat-tgt, frat-apart, unrelated
study mono and di twins raised together, apart.
limitation to raised apart: raised by relatives, separated not immediately at birth
-
Criticism
twins look alike - so are they similar because people treat themsimilarly or bc of genetic difference
-
Flynn Effect: IQ keeps going up 3pts per decade, but cannot be due to genetics because evolution is not that fast - has to be environment eg more nourished people
-
Stability/Change?
-
-
phase 3: depends
crystallized intelligence: wisdom/accumulated knowledge eg vocab/analogies, increases
fluid intelligence: ability to reason speedily and abstractly eg logic problems decreases at 20-85, then rapid decline
-
4+: intelligence test begins to predict adolescent and adult scores, smarter = usually live longer
facilitate education, job, envi
-
-
-
Spearman's general intelligence (g): underlies specific mental abilities and is measured by every task in an intelligence test
-
Kanazawa: g evolved as a form of intelligence that helped ppl solve novel/unfamiliar events, not routine events
-
-
Multiple Intelligences
-
-
-
criticism - intuitively possible but g factor shows correlation, success = talent +grit
Emotional Intelligence: ability to perceive, understand, manage and use emotions
perceive emotions (in face, music, stories)

-
-
Principle
standardization: defining uniform test procedures and meaningful scoring by comparison with the performance of a pretested group - has to reflect bell curve
-
-
reliable can mean not valid, but not reliable cannot ever be valid
Ethnic/Race diff
-
-
even if intelligence is 100% genetic, does not explain group differences
genetic does not mean a situation is unchangeable eg born short sighted can hv glasses to correct for it
-
Stereotype threats
-
don't have to buy stereotype, just knowing the stereotype already affects you
Exp: gave difficult test to undergrad - if say it is measuring intelligence/ not say anything - race and gender construct comes into play and minority score lower
Exp: if say test is non diagnostic, people perform the same
-
-
Extreme:
-
Low
intellectual disability: IQ less than 70, difficulty adapting to demand of life
-
Down Syndrome: sever intellectual disability associated with physical disability caused by extra copy of chromosome
