Flynn Effect – Flashcards

• Substantial and long-sustained increase in intelligence test scores measured in many parts of the world from 1930 to the present day. • IQ tests are standarized to mean=100. • Flynn gathered raw data from many countries and observed the increase.

• The gain: 3 points per decade. • In comparison to modern norms, the average for people in 1932 would be 80. • Some researchers: it's only in the lower half of the distribution.

-Duration of average schooling has increased steadily -Increased familiarity of the general population with tests and testing -More stimulating environment -Improvement of Nutrition -Today's average adult from an industrialized nation is taller than a comparable adult of a century ago. -Analogous increases of head size, and by an increase in the average size of the brain

Scholastic Aptidute Test (SAT) decreses. Non-IQ in SAT declines. Flynn on SAT and IQ: maybe media stimulate fluid abilities but not learning and knowledge.

•Some recent data suggest decline of IQ. • Norwegian and Danish data: IQ raising stopped in mid 1990s and declined. • UK: teenagers' IQ dropped from 1980s 6 points

• Changes in the population - more immigrants, hard to compare with previous. • There is a limit to how much environmental factors can improve intelligence.

• Negative correlation. • There is a limit to how much environmental factors can improve intelligence. • Meisenberg has argued that both higher GDP and IQ independently reduce fertility. • The average IQ of the young world population would decline by 1.34 points per decade and the average per capita income would decline by 0.79% per year.

individual differences in the pattern of bioenergetic trade-offs between the domains of mating, parenting and maintenance which allow organisms to adapt their fitness to the demands of either unstable or stable environment

•not many children, high parenting and maintenance effort. • Slow individuals exhibit differentiated abilities and cognitive specialisms as an adaptation to intra-specific competition, which is characteristic of populations living at the carrying capacity of stable environments.

•high mating effort, the reproduce ability is crucial. Have many children, less carrying. • Fast individuals need much more strongly integrated abilities in order to cope with unstable environments and unpredictable people.
