A
modeling
19
Q
o Children start with a Schema: way of understanding world
o Go into the world and gain Experience: biological or environmental change
o Then adapt their schema:
♣ Assimilation (large–> small blocks)
♣ Accommodation (blocks–> legos)
o With every experience they have, they should be updating their schemas
o Stages of cognitive development (know ages and first two)
♣ Sensorimotor
♣ Pre-operational
♣ Concrete operational
♣ Formal operational
A
constructivism
20

A
o Zone of proximal development
22
Q
o Environment of evolutionary adaptiveness (EEA)
♣ Ex: fight or flight
o Survival of the fittest
o Skills that children have are evolutionary adaptive (crying, motor skills etc.)
A
evolution darwin
23
Q
• Ecological systems theory
A
o Takes focus off of the individual
o Focuses on larger systems
o From direct (friends, family, school) to very indirect (culture that they’re in, government that their under)
o Family systems therapy
24
Q
cultural tools
A
• Material:
o The way your bedroom looks–boys typically messier than girls
o Different kinds of toys you give to each gender
• Symbolic
o Beliefs, values, and expectations are all built from conversation etc.
25
how is culture inherited?
o Imitation
o Explicit instruction
o Symbolic communication
26
what genetic makeup is
genotype
27
observable traits
phenotype
28
prenatal period
germinal, embryonic, fetal
29
germinal
♣ Conception (8-10 days)
| ♣ Cell proliferation
30
exist in early stages that can become anything, go in any direction can become liver, brain, etc.
♣ Totipotent stem cells
31
o Embryonic
```
♣ Germinal period- week 8
♣ When zygote gets implanted and become embryo
♣ Amnion and chorion are formed
♣ Placenta
♣ Umbilical cord
♣
♣ Cell differentiation (gastrulation)
♣ Epigenesis
```
32
o Fetal
♣ Embryonic period-birth
♣ All systems are present
♣ Increase in complexity and mass
♣ Responsive to environment
33
o Labor and birth
♣ 38-42 weeks gestation
| ♣ 3 stages: contractions(uterus is squeezing in on baby), PUSH, after-birth (placenta comes out)
34
childbirth in US
most are hospital births, and have an effect on the childs development
35
brain development
born with 10 billion neurons
36
experience-dependent
child are developing and learning about whats in their environment
37
experience-expectant
ready for certain input (sensitive periods)
38
phoneme distinction
babies can distinguish between phonemes within the first few months of life. can hear all different sounds
39
babies hear sounds produced in their native language
6-8 months
40
face recognition
```
o Innate preference for faces
o Face-like forms
o Preferences—upper vs lower half
o Configuration vs. feature differences
o 3 to 4 month year olds were sensitive to configuration
```
41
taste
o sweet preference: its calming, pain relief (because breast milk is sweet)
o don’t like sour and bitter, they make a face
42
intermodal perception
ability to combine senses
43
reflexes
grasping, sucking, rooting etc.
44
sensorimotor stage
coordinate sense with movement
45
sub stage 1
exercising reflex schemas: practicing their reflexes
46
subs tage 2
primary circular reactions: expand reflexes to new situations (can suck more than just nipples and repeat these)
47
difference between sub stage 1 and sub stage 2
go from noticing reflexes to actually using them for better more satisfying purposes
48
fine motor skills
what they can do with their hands (reaching, grasping)
49
gross motor skills
whole body (Crawl, walk)
50
fear of heights
developed around 9 months. Learned by experience
51
conceptual development
starting to move from sensorimotor to representational. starting to represent things in the world in their mind
52
object permanence
objects exist when out of sight
53
A not B error
hide toy then move it to a new location to hide right in front of them, and see if they can find the toy in the new location
54
criticism of Piaget
the tasks he had the kids doing were too difficult
55
alternative research methods
violation of expectations: show a kid something that couldn't happen, and see their reaction
56
counting
o Sense of numerical properties, looking tasks, surprised at wrong numbers, intermodal
57
• Cause-effect relationships
```
o Squares bumping into squares
o Causal or non-causal condition
o Stared longer at non-causal
o More complex objects
o Learning process...
```
58
categorization
kids will group birds and airplanes together because they look the same
59
two ideas regarding infant's emotions
differentiation and ontogenetic adaptation
60
differentiation
children seem to have fewer emotions, but have all emotions as adults but express them in a different way (crying)
61
ontogenetic adaptation
emotions serve a different purpose than adult's emotions (ex: smiling...random)
62
intersubjectivity
shared emotional connection between a child and their caregiveer
63
primary intersubjectivity
interaction between infant and caregiver
64
secondary intersubjectivity
interaction with other things in the world
65
intersubjectivity gone wrong
still-face study
66
attachment
parent-child bond. • Sense of security
| • Established by 7-9 months
67
attachment theories
drive reduction theory: freud's theory, the reason children become attached is because they need food from parents.
ethological theory: bowlby's theory, the parent serves as secure base of exploration for child
strange situation: separation and reunions
68
secure attachment strange situation
Strange situation task Child’s behavior
With parent. Freely explores
With stranger or alone. Exploration limited. Often upset.
Reunion Easily conforted. Returns to exploring.
69
ambivalent/resistant strange situation
Strange situation task Child’s behavior
With parent. Cautious. Low self exploration
With stranger/alone Very upset and negative
Reunion Not easily comforted. Seeks and resists affection
70
avoidant
Strange situation task Child’s behavior
With parent Freely explores. Ignores parent
With stranger or alone Not upset
Reunion Ignores or avoids parent
71
disorganized/traumatic
Strange situation task Child’s Behavior
With parent Disorganized, confused, often fearful
With stranger or alone Disorganized and confused, often fearful
Reunion Disorganized, confused, often fearful
72
Attachment: Socioemotional trajectories
* Secure: feel in control, low psychopathology
* Ambivalent/resistant: lack of control, anxiety and depression
* Avoidant: worse social relationships, behavior problems
* Disorganized/traumatic: world in incohesive, low sense of self, behavior problems, aggression, emotional dysregulation
73
developing sense of self
• 18-24 months
o differentiate self from others
o rouge test: put them in front of mirror and see if they can realize they are looking at themselves
o is the “self” just for humans
74
Social referencing
• Using others’ faces/emotions to understand ambiguous situations
visual cliff
75
language development
* requires biological and environmental inputs
* Universal progression
* Requires linguistic inputs
* Social-cultural variations
76
Pre-speech patterns
```
o Cooing (2-2.5 months)
o Babbling (7-9 months)
o Jargoning (9-12 months)
o First word (12 months)
```
77
o Speech production
broca's area
78
o Language comprehension
wernicke's area
79
left hemisphere
language is more strongly located on the left side
80
noam chomsky
idea of universal grammar, language is innate and hard wired in people.
81
can primates learn language?
o Kanzi (Bonobo and the rumbaughs): did the tasks that the lady asked him to do
o Lexical keyboard and reinforcement learning
o 2-word uterances
o vocabulary (100’s of words)
o comprehend novel sentences?
82
how environment affects language development
o Genie
o Deaf children in non-signing homes
♣ Rudiments of language
♣ Low complexity
83
when two kids come together from different languages, kids can take grammatical structures of both and develop mixed language and it becomes a new language
pidgin languages
84
multi-lingualism
does it help or hurt language development
85
brain development in early childhood
* Myelination of frontal cortex
* Length and branching of neurons
* Synaptic pruning
* Uneven change--- > variable development
86
Preoperational stage (Piaget)
* 2-6 years
* transition out of sensorimotor
* mental operations begin
87
centration
o fixate on one feature
o that thing is usually an immediate experience (no objectivity) start over generalizing, for example you see a CD player in a car and would expect them to be in all cars. Centered on one feature.
88
• Egocentrism
o Unable to take others’ perspective: can’t see things from another person’s perspective
o 3 mountains study
89
• confusing appearance and reality
o maynard the cat: cat wearing dog mask. Younger kids would say dog etc. older would say cat wearing a dog mask.
o Adults in costume
90
Precausal Reasoning
```
• Correlation = causation?
• Reverse causality
• Complexity?
• Snoopy!
o Ball causing snoopy to pop up, which ball? One or two
```
91
How do kids do this? (develop different forms of reasoning)
• Privileged domains
o Specialized, hard-wired forms of reasoning
o Born with naïve/rudimentary understanding of cause
o Directs attention to key features of environment
o Builds knowledge and skills
92
• Naïve Physics
o We are born to understand basic physical laws such as:
♣ Gravity
• Violation-of-expectations
• 5 vs. 7 month olds
• only 7 months looked longer at wrong acceleration
♣ gravity and inertia
93
• Naïve Psychology
o Theory of mind: theories of how other people think
o False belief tasks: seeing if you can trick a kid
o Influence of language and culture
94
Modularity Theory
```
• Distinct, innate mental modules
• Triggered by environment
• Autism and theory of mind
o Naïve psychology: impaired
o Naïve physics: often intact
o Fail false-belief tasks
```
95
Theory Theory
• General theory-making ability
• Applied to specific domains
• Modified with experience
• Evidence—appropriate theories in given situations
o Ex: boys hangs on branch-- > falls
o Ex: boy steps off stool wanting to float-- > falls, disappointed
96
♣ Psychodynamic
* Vast majority of our behavior is a way to resolve internal conflicts
* Oedipus complex states that boys have a desire to kill dad, have sex with mom. Guilt reaction: identify with dad, distance from mom.
* Electra complex: Girls have desire to have a penis, kill mom, have sex with dad. Guilt reaction: identify with mom, distance from dad
* Evidence? No. untestable!
97
♣ Social learning
* We model what we see
* Differential reinforcement: girls are rewarded for “girl behaviors” and boys are rewarded for “boy behaviors” or get punished
* Role models? Parents, teachers, older siblings
98
♣ Cognitive development
• Taking a constructivist point of view
o New cognitive skills--- > identity formation
• 3 stages (Kohlberg)
o 3 years: sex identity: can label yourself as boy or girl
o 3-5 years: sex stability: understanding that what sex you are in that moment is what you’ll be when you’re older
o 5-6 years: sex role constancy—can’t change your sex. No confusion of appearance vs. reality. Where is the start of sex-type behavior?
99
♣ Gender schema
• Starts very early
• Little kids get mental model of sex roles, attention is going to be guided towards these things. (encourage or discourage gender roles)
• Scripts for familiar events
• Information processing: boys/girls are being guided to attend certain activities
o Toy choice--- > kids ask themselves: is it relevant to me?
o Yes? Gender category
o No? forgotten
100
♣ Cultural
• Gender roles
o Relative emphasis
o Rigidity of boundaries
• Girls can act like boys but its not as normal is boys act like girls
o Why? Possibly because male stereotype is stronger.
101
♣ Ethnic Identity
• In-group and out-group attitudes
• Clark & clark: “white bias” children chose white doll to play with
o Why? Identify with majority group? Devalue minority group? Desire for equality. Ex: power, wealth
o Less white bias when:
♣ Less power differential
♣ Greater parental activism
102
♣ Ethnic Socialization
• Ethnic relevant messages
• 4 types:
o Cultural socialization: pride in ethnicity
o Preparation for bias: ethnic discrimination
o Promotion of racial mistrust
o Egalitarianism: all equal
103
• African American parents
o 88%- had messages of cultural socialization
o 65%- had messages of racial mistrust
o higher cultural socialization--- >higher cognitive skills
104
♣ Personal Identity
* I-self: subjective, sense of stable sense over time. Solidified in teenage/early adult years.
* Me-self: objective, in the moment, current physical characteristics.
105
```
• Young kids: more at me-self. Preoperational (low representational ability.) Unrealistically positive self-evaluations. Real self vs. ideal self.
• Autobiographical memory
o Personal narrative
o Creates continuity in self
o Parents
♣ Help kids recall events
♣ Probe and make connections
♣ Embellish or diminish details
o Growing independence
```
