***Chapter 9: Human Development Flashcards
1
Q
developmental psychology
A
the study of how behavior changes over the life span
2
Q
MAOA gene
A
a gene that causes low production of MAOA enzyme, which causing heightened risk for developing into a criminal
3
Q
nature-nurture debate
gene-environment interactions
A
the impact of genes on behavior depends on the environment in which the behavior develops
4
Q
nature-nurture debate
example of gene-environment interactions
A
MAOA gene + delinquent peer -> violent behaviors
5
Q
nature-nurture debate
nature via nurture
A
genetic predispositions can drive us to select + create particular environments that influence our behaviors, leading to the mistaken appearance of a pure effect of nature
6
Q
nature-nurture debate
example of nature via nurture
A
quiet children seek out quiet environments that reinforce the quiet nature
7
Q
nature-nurture debate
gene expression
A
some genes “turn on” only in response to specific environmental triggers
8
Q
nature-nurture debate
example of gene expression
A
early family loss triggers the genes that predispose one to anxiety to be turned on
9
Q
nature-nurture debate
epigenetics
A
whether genes are active is regulated day-by-day + moment-by-moment environmental conditions
10
Q
nature-nurture debate
example of epigenetics
A
genes that are turned on don’t necessarily stay on because of environmental factors
11
Q
during the course of human development, developmental influences are ____
A
bidirectional
12
Q
cohort effect
A
effect observed in a sample of participants that results from individuals in the sample growing up at the same time
13
Q
cross-sectional design
A
research design that examines people of different ages at a single point in time
-snapshots
-no control for cohort effect
14
Q
longitudinal design
A
research design that examines development in the same group of people on multiple occasions over time
-examines true developmental effect
-costly, time-consuming
15
Q
post hoc fallacy

the mistake of assuming that because A comes before B, A must cause B
16
Q
zygote
A
fertilized egg
17
Q
blastocyst
A
ball of identical cells that hasn’t yet begun to take on any specific function in a body part
-zygote divides to form this
18
Q
course of prenatal development
A
germinal period, embryonic period, fetal period
19
Q
prenatal development
germinal period
A
first 2 weeks after conception
-first week: the fertilized egg (zygote) + divides to form blastocyst (a ball of identical cells that haven’t yet begun to take on any specific function in a body part)
second week: embedding of blastocyst in the uterine wall (implantation); differentiation of cells/task specialization begins
20
Q
prenatal development
embryonic period
A
2-8 weeks after conception, blastocyst becomes an embryo
-limbs, facial features, major organs begin to take shape
-life support systems (amnion, umbilical cord, placenta) develop
-spontaneous miscarriages often occur during this period
21
Q
prenatal development
in what period do spontaneus miscarriages tend to occur?
A
embryonic period
22
Q
prenatal development
fetal period
A
2 months after conception until birth
-heart begins to beat
-embryo becomes fetus
-major job is physical maturation, fleshing out
-last third of pregnancy for bulking up
23
Q
prenatal development
brain development time period
A
18 days of pregnancy + beyond
24
Q
prenatal development
brain development
A
-brain continues to develop into early adulthood
-between 18th day of pregnancy + end of 6th month, neurons begin developing at astronomical rate (proliferation)
-4th month + throughout pregnancy, migration of cells begins to occur, moving to final positions in specific structures of brain
25
# prenatal development
what occurs between 18th day of pregnancy + end of 6th month
neurons begin developing at astronomical rate (proliferation)

34
cognitive developmental theories differ in 3 core ways
-is cognitive development stage-like or continuous?
-is congitive development domain-general or domain-specific?
-is cognitive development out of physical experience, social interaction, and/or biological maturation?
35
domain-general
relies on social interaction as a source of support
36
domain-specific
depends on biological maturation
-continuous
37
Piaget's theory of cognitive development
-1st to present a comprehensive account of cognitive development
-children are active learners with different understanding of the world from adults
38
according to Piaget's theory of cognitive development, development is
-continuous or stage-like
-domain-general or domain-specific
-via ____ interaction
-stage-like
-domain-general
-physical interaction
39
according to Piaget's theory of cognitive development, cognitive change is a result of what
children's need to achieve equilibration
40
# Piaget
equilibration
balance between the experience of the world + the understanding of it
-disequilibration -> equilibration -> disequilibration...
41
# Piaget
assimilation
the process of absorbing new experience into our current understanding
42
# Piaget
accomodation
the process of altering beliefs about the world to make them more compatible with experience which leads to stage changes
43
order of Piaget's stages
-sensorimotor
-preoperational
-concrete operational
-formal operational
44
stages of Piaget's theory of cognitive development
sensorimotor stage:
-0-2 years old
-child begins to interact with environment, no thought beyond immediate physical experiences
-mental representation is assessed by object permanance task
preoperational stage:
-2-6/7 years old
-child begins to represent the world symbolically, able to think beyond here + now, but egocentric + unable to perform mental transformations/operations
-mental transformation assessed by 3 mountain task
concrete operational stage:
-7-11/12 years old
-able to perform mental transformations but only on concrete physical objects
-assessesd by conservation task
formal operational stage:
-12-adulthood
-adolescent can transcend concrete situations + think about future
-ability to perform hypothetical + abstract reasoning assessed by pendulum task
45
# Piaget
how is the sensorimotor stage assessed
object permanence task
46
# Piaget
object permanence task
if you hide a toy under a blanket + infant knows the toy is under the blanket by finding it
47
# Piaget
how is the preoperational stage assessed
3 mountain task
48
# Piaget
3 mountain task
a child is faced a display of 3 model mountains while a researcher places a doll at different viewpoints of the display
-they should be able to recognize from all 3 views
49
# Piaget
how is the concrete operational stage assessed
conservation task
50
# Piaget
conservation task
if 2 children are shown 2 identical objects but in different organizations (like 1 cookie broken in half + the other broken in quarters)
-they should be able to recognize it is the same amount of cookie
51
# Piaget
what assesses the formal operational stage
pendulum task
52
# Piaget
pendulum task
compare motions of longer + shorter strings, with lighter + heavier weights attached, in order to determine the influence of weight, string length, + dropping point on time it takes for pendulum to swing back + forth
53
pros of Piaget's theory
-view children as different in kind from adults
-learning is active (cognitive constructivist)
-parsimonious general account of cognitive processes
54
cons of Piaget's theory

57
# Vygotsky's theory
zone of proximal development (ZPD)
phase of learning during which children can benefit from instruction
-emphasizes continuous development, social interaction, + no domain general stages

level of additional responsibility the child can accept with assistance of an able instructor
59
# Vygotsky's theory

60
# Vygotsky's theory
how do children learn language...during 1st year or so after birth
infants learn much more about the sounds of their native language
-babbling as intentional vocalization that lacks meaning
61
# Vygotsky's theory
how do children learn language...by the end of their 1st year
infants' babbling takes on a conservational tone that sounds meaningful though isn't
62
# Vygotsky's theory
in early word learning... comprehension precedes/follows production
comprehension precedes production
63
# Vygotsky's theory
how do children learn...around their 1st birthdays
children start to produce their 1st words with variability in this milestone
64
# Vygotsky's theory
describe syntax development
1-word stage -> 2-word stage -> more complex sentences with 3/4-word combinations with morphological markers -> acquire most syntactic rules by preschool age -> acquire more complex rules in early school years
65
# Vygotsky's theory
critical period
narrow windows of time in development during which an organism but learn an ability if it’s going to learn it at all
66
# Vygotsky's theory
sensitive period
an interval during which period are more receptive to learning + can acquire new knowledge more easily
67
what is wrong with the theory that children learn language through imitation
this can't explain the generativity of language, like using finite vocab for infinite word expressions
68
