Why do we study social development?
Interactions with caregivers and peers emotional expression social skills influence of media/culture/family different aspects of development- cognitive language, physical, etc- underlie social behavior
Practical applications of the research
Educators, medical professionals, parental guidance/counseling, policy makers
How so biological and environmental influences affect social development?
Genetics X environment (not either/or)
 ie: aggression can be because of increased levels if testosterone but this can be pulled out of the environment as well
Genie example
Girl was locked up for 12 years
 deprived of all sensory stimulation
 had no language
 malnourished

Critical periods
Certain point in ones development in which your brain expects to get certain info Ex: Romanian orphanage children at 1yr we're able to recover but had long term effects
What role do children play in their own development?
Children actively explore their environments
 the world changes for them as they learn to crawl, walk, talk, etc

Transactional model of social interactions
Interactions are always bidirectional and are always changing Interactions are like a cycle, continuing to affect the next response
What is the appropriate unit for studying social development?
SOCIAL DYADS-- important to look at pairs of social interactions (ie parent-child interaction) Social groups
Is development continuous or discontinuous?
If you look very closely, a child's development looks very gradual or continuous If you look at more of a birds eye view development may look more step like
Is social behavior the result of the situation or the child?
The situation can have certain circumstances that bring out different traits of the child As children get older,they may be choosing their situations more, therefore acting the same Developing independence and self concept
Is social development universal across cultures
Culture-free laws of development: acquiring the basic foundations of social life OR variation in beliefs and child rearing practices across cultural settings
Universals in social development
Development and progression of language Emotions Communications
How does social development vary across historical eras?
Gradual shifts: family timing and structure, modes of communication, mothers working outside the home Significant events affect social development of children at that time
Is social development related to other developmental domains?
Cognitive: executive functions, emotion regulation, interpret language Language development Motor development Reciprocal nature of cross domain influence
Is there a single pathway of social development?
Multi finality: we start in the same place but end in many different places Equifinality: start in different places and end up in the same spot
What influences how we judge children's social behavior?
Characteristics of the child (gender), appearance , temperament, the adults mental state Social judgements are important because they alter the way the child is treated
Do developmental psychologists own social development?
Scholars in a variety of fields have made valuable contributions to the field of social development (Neuroscience, genetics, sociology, biology, etc)
Cognitive social learning theory
Children learn by observing and imitating others (Bandura/bobo doll) Imitation requires cognition Reciprocal determinism Self efficacy
Reciprocal determinism
Children's actions produce responses by other people, leading to changes in the social environment and changes in the child
Self-efficacy
How well a child deals with social interactions is influenced by self efficacy
Social information processing theory
How children assess social situations affects how they act Notice social cues Interpret cues Formulate social goals Generate possible problem solving strategies Evaluate probable effectiveness of strategies Enact response Peer evaluation and response
How are babies prepared- visual preparation for social interaction
Babies attracted to visual social stimuli (Faces, especially the eyes)
Vygotsky's sociocultural theory
Development emerges from social interactions and cultural factors Zone of proximal development Culture includes setting and practices and how these are presented to the child
Zone of proximal development
The assistance and guidance provided by others is what pushes children to develop to their full potential
Bronfenbrenners ecological theory
Microsystem: immediate family, teacher, peers  Mesosystem: interactions between Microsystems Exosystems: media, neighbors, parents workplace Macrosystem: cultural values, beliefs, community Chronosystem: historical context, age cohort, big events
Ethnological theory
In order to understand development, you must account for the child's biology at the time and the ecosystem its in Universal behaviors- emotions: communication and survival mechanism
Human behavior genetics
Influence of heredity on social traits Using statistical estimation, how much heredity influences behavior and traits
Life span perspective
Extends development into adulthood Normative events vs nonormative  Age cohorts
How are babies prepared- biological to social rhythms
Parents try to get baby on their sleep-wake cycle Acquisition of biological regulatory skills interactional synchrony Development of biological rhythms that help babies deal with the time-based nature of social interaction
Auditory preparedness for social interaction
Well developed before birth Prefer high pitch and exaggerated contours (child-directed speech)
Why are babies prepared - social partner
Infants prefer face to face play to other activities Capable to regulating interactions with gaze
Why are babies prepared
Because infants depend on the support and nurture of parents for an extended period of time, they are biologically programmed to be responsive and have a set of social responses that ensures that their needs are met To make themselves attractive social partners
Cerebrum
The two connected hemispheres of the brain
Cerebral cortex
Layer covering the cerebrum  Covers specific functions
Cerebral hemispheres
Right hemisphere- visual and spatial information, nonspeech sounds, processing emotional information Left hemisphere- associated with language and emotion processing
Corpus callosum
Nerve fibers that connect the hemispheres of the brain
Lateralization
Each half of the brain becomes specialized for certain functions Begins early in life- if a child experiences brain injury, their brain can recover if not fully developed yet
Neurons
Most neurons are present in the brain by the seventh month after conception Multiply very rapidly by neuron proliferation
Myelination
Covers neurons with myelin to make transmitting of information more efficient
Synapse
Specialized site of communication between neurons
Synaptogenesis
The forming of synapses Begins early in prenatal life
Synaptic pruning
Disposes of under stimulated neurons Frees space for new synaptic connections
Experience expectant processes
At birth, there are certain experiences that our brain expects to have IE sensory stimulation
Experience dependent processes
How we are stimulated is different IE we grow up in different locations, therefore different experiences
Mirror neurons
Fire both when a person acts and when the person observes the same action Learn new skills by imitation, important for understand others actions and intentions Linked to language acquisition, theory of mind, and empathy
Human behavior genetics
Focused attention on estimating genetic contributions to the array of individual differences in social behavior
Heritability factor
How much our inheritance influences our traits/abilities
Adoption studies
Compare adopted children to biological and adoptive parents
Twin studies
Compare similarities between identical twins and fraternal twins
Passive gene environment association
Parents provide environment similar to their own phenotype
Evocative gene environment association
The way the child acts evokes different reactions from parents
Active gene environment association
Child actively makes decisions on activities that fit them Niche picking
G X E model
People in the same environment are affected differently depending on their genetic makeup
ADHD
Prefrontal cortex under developed (impulse control) Dopamine receptors work less Environmental and genetic factors
Operant conditioning
basis for the development of attachment is the visual, auditory, and tactile stimulation attachment is not automatic and develops over time
cognitive development theory
infant's ability to differentiate between familiar/unfamiliar people and the infants awareness that people still exist even when they cannot be seen
When is the earliest that children show object permanence?
3 1/2 months
secure base
a starting point from which the infant can venture forth to explore the world and a haven of safety to which he can return to in times of danger
Ethological theory
bowlby attachment is linked to exploration develop mutual attachments
Preattachment
0-2 months indiscriminate social responsiveness
Attachment in the making
2-7 months recognition of familiar people
Clear cut attachment
7-24 months separation protest, wariness of strangers
goal corrected partnership
24 months on relationships more two sided; children understand parents needs
Phases of attachment
1. preattachment 2. attachment in the making 3. clear-cut attachment 4. goal-corrected partnership
