8: Intelligence; 9: Language Development Flashcards
Large Cohort Effects in Intelligence: The Flynn Effect + Causes
The rise in IQ scores over generations. People score higher than they would today when tested on older tests
May be caused by contextual changes in education, health, and nutrition → gains are pronounced in developing countries
As living conditions optimize, IQ scores should plateau
SES on IQ: Ethnic differences
developing countries tend to score lower
African-American and Hispanic individuals tend to have lower intelligence scores than other individuals
SES on IQ: Differences are not inborn
children adopted from low SES into higher SES score higher on IQ tests than siblings who are raised by birth parents or adopted into lower SES homes
African American children from low income environments adopted into middle-SES show IQ scores similar to national averages for mid-SES kids
children from similar middle-class backgrounds tend to have similar IQ scores regardless of their race or ethnicity
SES on IQ: Culture, Nutrition, Living conditions, School Resources, Intellectual stimulation, and life circumstances
better things help IQ :))
Phonology
knowledge of sounds used in a given language
Learning how to detect, discriminate, and produce speech sounds
Morphology
understanding the ways that sounds can be combined to form words
Infants learn that sounds can be combined in meaningful ways
example: 2 sounds put together are meaningful to us, and infants learn that they are meaningful!
Semantics
the meaning or content of words and sentences
growing vocabulary signals an increase in semantic knowledge
syntax
knowledge of the structure of sentences
rules by which words are to be combined to form sentences
pragmatics
understanding how to use language to communicate effectively. Intonation can be different (example: when asking a question, voice goes up in the end)
example: difference in speaking with a professor and a toddler
Contextual Influences on Language Development: Trends in Poverty
The higher your SES, the more the infants’ vocabulary expands when they get older (from 18 months to 24 months) compared to the children with lower SES
Graph shows that children with higher SES initially know more vocab than those with lower SES
