Exam 3 Flashcards
intelligence
ability to direct one’s thinking, adapt to one’s circumstances, and learn from one’s experiences
Henry Goddard
one of the first to measure intelligence, discriminatory toward Ellis Island immigrants
Alfred Binet & Theodore Simon
developed the first intelligence test to identify children who needed remedial education — measure aptitude apart from achievement
first intelligence test
to identify children who needed remedial education
ratio IQ
dividing a person’s mental age by physical age x 100
deviation IQ
dividing a person’s test score by the average test score of people in the same age group x 100
data-based approach to describing middle-level abilities
starts with people’s responses on intelligence tests and then looks to see what kinds of independent clusters these responses form
theory-based approach
broadly surveys human abilities and then determines which ones intelligence tests measure (or fail to measure)
fluid intelligence
ability to see abstract relationships and draw logical inferences
crystallized intelligence
ability to retain and use knowledge that was acquired through experience
Robert Sternberg suggested that there are three kinds of intelligence
analytic intelligence (problem solving) creative intelligence (novel solutions) practical intelligence (everyday)
heritability coefficient of intelligence
50%
heritability coefficient
the proportion of the difference between people’s scores that can be explained by differences in their genes
absolute intelligence
can change considerably over time
relative intelligence
generally stable over time
Flynn Effect
the average intelligence test score rises about 0.3% every year
how people of different ethnicities compare in terms of IQ scores
education increases intelligence
biggest reason why African Americans have lower intelligence scores than European Americans
education increases intelligence, beneficial neural changes can occur because of exercise, nutrition, and sleep
what percentage of zygotes do not complete the journey down the fallopian tube
about 50%
zygote
fertilized egg that contains chromosomes from both a sperm and an egg
germinal stage
2-week period that begins at conception
embryonic stage
2nd week until the 8th week
fetal stage
9th week until birth
myelination
formation of a fatty sheath around the axons of a neuron during the fetal stage
short eye openings, flat midface, indistinct ridge under nose, thin upper lip
fetal alcohol syndrome
cephalocaudal rule
‘top-to-bottom’ rule that describes the tendency for motor skills to emerge in sequence from the head to the feet
proximodistal rule
‘inside-to-outside’ rule that describes the tendency for motor skills to emerge in sequence from the center to the periphery
cognitive development
emergence of the ability to think and understand—how the physical world works, how their minds represent it, how other minds represent it
assimilation
process by which infants apply their schemas in novel situations
accommodation
process by which infants revise their schemas in light of new information
object permanence
idea that continues to exist even when they are not visible
conservation
notion that quantitative properties of an object are invariable despite changes in the object’s appearance
sensorimotor stage (birth-2 years)
infants acquire information about the world by sensing it and moving around with it
preoperational stage (2-6 years)
children have a preliminary understanding of the physical world
concrete operational stage (6-11 years)
children learn how various actions or operations can affect or transform concrete objects
formal operational stage (11+ years)
children can solve non-physical problems; abstract thinking
doesn’t communicate well, few friends, doesn’t understand the emotions of others, normal intelligence test score
autism
ability to learn from others—three fundamental skills
joint attention
social referencing
imitation
joint attention
ability to focus on what another person is focused on
social referencing
ability to use another person’s reactions as information about the world
imitation
ability to do what another person does
strange situation test
measures a child’s attachment style
attachment styles
secure, insecure: avoidant, ambivalent, disorganized attachment
quality of attachment between children and their mothers influenced most strongly by…
mother sensitivity and responsiveness
temperament
characteristic patterns of emotional reactivity—variant and stable
Kohlberg’s three stages of moral development
preconventional
conventional
postconventional
preconventional stage
childhood, morality of an action is primarily determined by its consequences for the actor
conventional stage
adolescence, morality of an action is primarily determined by the extent to which it conforms to social rules
