Bayley Scales of Infant Development (BSID)
the most well-known widely used test measuring intelligence for young children
- created for 1-42 months and measures social-emotional skills and adaptive
- three scales
three scales of the Bayley Scales of Infant Development
- the motor scale: measures the ability to do things like grasp an object and throw a ball
- the cognitive scale: measures how the young child thinks and reacts to various typical events
- the language scale: measures preverbal communication
general adaptive composite (GAC)
this data shows how well or poorly a young child performs on the BSID
- however correlations between GAC and IQ score are low
correlation between GAC and IQ
- there is not a high correlation at a later age
- but when looking at the age of 4, correlations are high
creativity
mapped by measuring how many different ideas a child can produce
- ideas peak until the child is 9 years
- decreases after the 11th year
originality
how many original ideas a child has
- peaks until the child is about 10 years old
changes in the adolescent brain
may underlie various cognitive abilities, such as improved memory, information processing and performance on intelligence tests
Flynn effect
average IQ scores have increased over time
reasons for the Flynn effect
- children have better education than previous generations
- economic conditions have improved
- better health
predictors of school performance
- intellectual abilities (especially during secondary school)
- personal qualities (e.g. motivation)
relationship between IQ scores and employment status of adults
intelligence is related to both income and job prestige
- takes more intellectual skills to complete a degree
- people with higher IQ’s are healthier and live longer
correlation between success and intelligence
can be explained by SES, motivation, education, and opportunity
cohort effects and intelligence
your intelligence score depends on when you were born
risk factors for a decline in intellectual abilities
- poor health
- unchallenging lifestyle
wisdom
a constellation of factual knowledge about life and procedural knowledge such as giving advice and resolving conflicts
- a combination of intelligence, personality, cognitive style, and a supportive social environment
when does creativity peak
in creative professions (art, music, philosophy, science) creativity is seen to increase from the 20s to the early 40s
- requires enthusiasm and experience so peaks in midlife
why do people differ in IQ scores
both genetic and environmental factors
- 50% of variation in IQ scores is due to genetic differences
influence of genes on intelligence
not the same throughout life
- 20% of the differences in intelligence for babies
- 80% for older people
risk factors for having a lower IQ score
- child belongs to a minority group
- head of the househould has no job
- mother didn’t finish school
- family has 4 or more children
- father is absent
- family has experienced many stressful events
- parents have rigid education values
- mother is very anxious/stressed
- mother has poor mental health
- mother shows little positive affect
cumulative limitation hypothesis
states that children who live in poverty for a long time or who have a low SES cannot develop themselves cognitively quickly
- improving economic living conditions can therefore also improve children’s IQ
Home Observation for Measurement of the Environment (HOME)
used to identify characteristics of the environment that are important for cognitive development
- can predict the IQ scores of 3 year old children
crying
crying is an important way for babies to communicate
- babies who seldom (rarely) cry may have neurological problems
- necessary for a baby to survive
babies who cry continuously
may have colic
- caused by an immature nervous system
- babies experience so much stress after birth due to all the stimuli that they experience
- colic is short lived and disappears around 4 months
what did Skinner believe about language learning
Skinner believed that we learn language by being empowered to produce sounds
Chomsky (1928)
humans are biologically programmed to produce language through the language acquisition device (LAD) (nature)
- people learn to speak a language through the spoken language in their environment
- suggest that language is a fundamental aspect of the human mind, influenced more by innate structures than by external environmental factors alone
social-interactionist perspective of language
babies are motivated to communicate and adults are motivated to help babies learn to speak (nature + nurture approach)
the emergence of language
occurs in stages
- after the new-born’s reflexive crying comes cooing (3rd/4th month)
- vocal circular responses, also known as babbling (6 months)
- first word emerges from babbling (11 months)
