Q

4 goals of developmental psychology

A

1) description - describe what is happening
2) explanation - why is that happening
3) prediction - can we predict when this will occur and who is involved

25
Blastocyst
4th day of conception, zygote arranges itself into hollow sphere (blastocyst) with a bulge of cells on one side * inner cell mass forms into embryo * twins are formed in this stage
26
Embryonic Period
3rd week - 8th week major development occurs in all the organs and systems of the body * inner cell mass becomes embryo
27
Neural tube
U shaped groove formed from the top layer of differentiated cells which eventually becomes the brain and spinal cord
28
Spina Bifida
part of the spinal cord is not fully encased in protective covering of the spinal column
29
Anencephaly
failure to close at the top of neural tube, fatal due to main portion of brain not developing
30
Placenta
permits exchange of materials between the bloodstream of the fetus and mother placental membrane = barrier against some toxins and infectious agents
31
Umbilical cord
tube that contains the blood vessels that travel from the placenta to the developing organism and back again
32
amniotic sac
membrane filled with fluid to protect fetus
33
Cephalocaudal development
areas near the head develop earlier than those farther away
34
Fetal period
9th week - birth continuing development of physical structures critical process for brain development
35
Age of viability
survival outside of the uterus may be possible week 26
36
When are movements developed
12 weeks
37
When are sensory structures developed
sound = 6th month
38
Tactile stimulation
activity within the womb (touching face and body)
39
When can fetuses learn
32 weeks
40
Habituation
simple form of learning, fetus gets used to sounds and stimuli and doesn't react to them anymore
41
Evidence of learning:
newborns prefer sounds, tastes and smells that they experienced prenatally newborns recognize rhymes and stories that were present before birth
42
What percent of conceptions and pregnancies end in miscarriage
45% of conceptions, 15-20% of pregnancies
43
Teratogens
disease, drug, or environmental agent that can harm a fetus
44
Sensitive/ critical period
period of time where teratogens effect fetus the most (20-35 days) found due to thalidomide
45
DES
medication used to prevent miscarriages and premature babies 1971 -> was found that utero exposure to DES was linked to greater risk for cervical and testicular cancers
46
Thalidomide
drug used to relieve morning sickness < 20 days: no effect 20-22 days: no ears 22-27 days: missing thumbs 27-33: stunted legs >35 days: no effect this is how critical period was found out
47
Cigarette smoking effect
delayed growth, low birth weight, sudden infant death syndrome
48
alcohol effects
fetal alcohol syndrome, intellectual disability, facial deformity
49
Marijuana effects
negatively affects memory, learning, and visual skills
50
cocaine effects
delayed growth & premature birth, impaired ability to regulate arousal (some lethargic and some highly excited)
51
Gene- environment interactions
effects of genes depend on what kind of environment we experience ex: MAOA gene -> in environments of abuse & low MAOA = more likely to engage in antisocial behavior
52
Diathesis stress model
psychological disorder results from interaction of a person's predisposition and the experience of stressful events
53
Differential susceptibility hypothesis
some people's genes make them more reactive than other people to environmental influences
54
Parts of neuron
cell body - basic biological material to keep neuron functioning dendrites - receives input from other cells and conducts it towards cell body axon - conducts electrical signals to connection with other neurons (synapses)
55
proximodistal principle
growth and development of muscles from center outward to extremities
56
orthogenetic principle
development starts globally and undifferentiated
57
neurogenesis
formation of neurons via cell division * 18 weeks after conception axons elongate, dendrites form spines to increase capacity, formation of myelin sheath around axons
58
Synaptogenesis (and synaptic pruning)
growth of synapsis pruning: removal of unnecessary synapses
59
occipital lobe
very back of brain; processes visual information
60
temporal lobe
on sides of brain; processes hearing and emotions
61
parietal lobe
top of brain; processes and integrates sensory input with information in memory
62
frontal lobe
organizes behavior, responsible for planning
63
Adolescent brain
gray matter increases (increased synaptogenesis right before puberty) dorso-lateral prefrontal cortex is the last to mature (responsible for impulses and priority setting)
64
Adult brain
brain weight and volume decrease over adult years dendrites continue to grow degeneration and plasticity (unable to learn things as easily as an adult)
65
Neurocognitive maintenance
regular upkeep of the brain
66
neurocognitive reserve
stockpile of neural resources that we saved up during our lifetime, overusing leads to burnout
67
Compensation
ability to enlist the help or neural resources when faced with challenging task
68
experience expectant plasticity
normal wiring of the brain based on experience almost ALL humans have
69
experience dependent plasticity
neural connected are created as a function to the specific experiences of an individual (example: learning to play an instrument)
70
Theory
set of ideas to describe and explain certain phenomena * falsifiable and supported by data
71
Evolutionary theory of development
evolution of human species as explanation of why humans are as they are and develop as they do Dawrin, Tomasello
72
Psychoanalytical theory of development
people are driven by motives and emotional conflicts; shaped by earliest family experiences Freud, Jung, Erikson
73
Learning theory of development
learning is the major contributor to human development; classical and operant conditioning Pavlov, Skinner, Bandura
74
Cognitive developmental theory of development
children construct knowledge and ways of thinking using their experiences and proceed through universal stages Piaget
75
Bioecological systems theory
changes over the lifespan arise from ongoing interactions in which a changing person and changing environment affect one another
76
Urie Bronfenbrenner's Bioecological model
1) microsystem: immediate environment (interactions with family, friends, etc) 2) mesosystem: connections across microsystems (friend to family, without individual) 3) exosystem: environmental setting the person does not experience directly but may affect them indirectly (parents' workplace) 4) macrosystem: larger cultural context 5) chronosystem: time/ historical changes that influence systems
77
Piaget's 4 stages of development
1) sensorimotor 2) preoperational 3) concrete operational 4) formal operational
78
Sensorimotor stage
birth - 2 years infants know the world through their senses and their actions develop object permanence
79
object permanence
knowledge that objects have permanent existence without our perceptual contact with them
80
A-not-B error
8-12 month olds search for an object in place where they last found it
81
Path to object permanence
0-4 months: infant wont search for object hidden from view 4-8 months: infants will retrieve toys partially covered or beneath transparent cover but not completely hidden 12-18 months: search for object completely hidden, but struggle with invisible displacement (figuring out where something is hidden if they didn't see it being hidden) 18-24 months: capable of mentally representing invisible displacements
82
Preoperational stage
2-7 years old acquire ability to internally represent the world through language and mental imagery begin to see the world from other people's perspective
83
symbolic representation
the use of one object to stand for another (pretend play)
84
egocentrism
tendency to perceive the world solely from one's own point of view
85
centration
tendency to focus on single, perceptually striking feature of an object or event
86
conservation tasks
children in pre-operational stage fail two cups hold same volume but different shapes, children will prefer the tall cup because it looks like it has more liquid
87
concrete operational stage
7-11 years children begin to think logically can classify objects into categories understand events are influences by multiple factors pass conservation tasks fail to think systematically
88
pendulum problem
children below 12 perform unsystematic experiments to draw incorrect conclusions Will take different length rope and different weight to test. Doesn’t show you which is the determining thing that causes the swing of pendulum
89
class inclusion
understanding that parts are included in a whole category (dog is part of the grouping of animals)
90
Transivity
necessary relations among elements in a series A>B>C so A>C
91
Formal Operational stage
12 years - onward adolescents can think systematically and reason about what might be as well as what is understand politics, ethics, science fiction Piaget believes attainment of this stage is not universal major achievement: ability to think hypothetically
92
adolescent egocentrism
difficulty differentiating one's own thoughts and feelings from those of other people
93
imaginary audience
confusing your own thoughts with those of a hypothesized audience for your behavior (think everyone is looking at you or talking about you)
94
Personal fable
tendency to think that you and your thoughts and feelings are unique
95
Postformal thought
more complex than formal-operational stage
96
Relativistic thinking
knowledge depends on its context and the subjective perspective of the knower
97
Dialectical thinking
detecting paradoxes and inconsistencies among ideas and trying to reconcile them
98
Piagets theory pros
asked important questions showed us infants and children are active in their own development taught us that young people think differently than older people do largely accurate
99
Piagets theory cons
stage model depicts children's thinking as being more consistent than it is infants and young children are more cognitively competent than Piaget recognized understates the contribution of the social world vague about cognitive processes
100
Lev Vygotsky
father of sociocultural approach to child development view children as social beings children intertwined with other people who are eager to help them gain skills and understanding
101
zone of proximal development
gap between what a learner can accomplish independently and what he or she can accomplish with the guidance and encouragement of a more skilled partner
102
implication of the zone of proximal development
knowledge is not fixed no single test or score can reflect the range of a persons knowledge development consists of moving towards the upper range of zone
103
Vygotsky argued:
language shapes thought thought changes fundamentally once we begin to think in words
104
language comprehension
understanding of language
105
language production
actually speaking language
106
phonological development
knowledge about phonemes (elementary units of sound)
107
semantic development
learn system of expressing meaning in a language starts with morphemes (smallest unit of language)
108
pragmatic development
acquiring knowledge of how language is used
109
brain damage to Broca's area
near motor cortex; associated with difficulties in producing speech
110
brain damage to wernicke's area
near auditory cortex; linked to difficulties with meaning (produce words but no meaning)
111
infant directed talk
mode of speech adults develop to talk to infants
112
prosody
rhythm, tempo, cadence in which language is spoken
113
cooing
6-8 weeks, start to understand that certain sounds bring their parents/what they want
114
babbling
6-10 months consonant followed by a vowel
115
holophrases
one word utterances
116
overextension
single word, used in a lot of scenarios where it may not even apply
117
underextension
using a word to represent only a small portion of the category (ex: doggie only for their own dog or type of dog)
118
whole object assumption
learn a new word, that word applies to the entire object not just an element (ex: key on laptop is part of whole computer not just one key)
119
mutual exclusivity assumption
leads to children to expect that a given entity will only have one name (ex: know word computer, refer to it as laptop, they will not understand)
120
pragmatic cues
aspects of social situation/context to learn words
121
theory of mind
understanding that people have mental states such as desires, beliefs, and intentions and that these mental stages guide their behavior
122
2 year old theory of mind
understand the connection between other people’s desires and their specific actions, but show little understanding that beliefs are also influential
123
3 year old theory of mind
understand that desires and beliefs affect behavior but have difficulty with false belief problems (tasks that test child’s understanding that other people will act in accord with their own beliefs even when the child knows that these beliefs are incorrect)
124
