Infancy and childhood

Developmental psychology- the study of how humans mature and why they develop how they do

grasping reflex- babies grasp objects when their palm is touched

Rooting reflex- when touched around the mouth, babies turn toward the touch

Babies born before week 37 are premature

Behavioral cues- measures infant’s abilities through behaviors

The strength of stimulus responses helps determine how babies perceive their environment

Maturation- complex growth

Babies learn language through imitation

Telegraphic speech- simple phrases that still show meaning

Grammar is unique to humans

Cognitive development- the growth of thought processes

Piaget studied how thinking develops

Schema- mental representations of the world

Assimilation- fitting new objects into existing schemas

Accommodation- changing schemas to fit new objects

Object permanence- realizing an object still exists even if it’s hidden

Representational thought- the ability to picture things in the mind

Representational thought also marks the shift between action based intelligence to symbolic thought

Conservation- a given quantity remains the same despite changes in appearance

Conservation shows up around 5-7 years old

Egocentric- only seeing things from one’s own perspective

Egocentrism decreases as children begin to see multiple viewpoints

Piaget’s stages of development

  1. sensorimotor

  2. Pre-operational

  3. Concrete operational

  4. Formal operational

sensorimotor is 0-2 years old

Pre-operational is 2-7 years old

Concrete operational is 7-11 years old

Formal operational is 11+ years old

Sensorimotor is learning through senses and actions

Proportional is the use of symbols and language, egocentric view

Concrete operational is logical thought with concrete objects

Formal operational is abstract thought and problem solving

Vygotsky’s approach

Zone of proximal development- children learn best from the help of others

Scaffolding- the support of others for help in learning

Scaffolding is gradually reduced as independence is gained

Imprinting- the tendency in some animals to follow the first moving object they see

Attachment styles

  • secure

  • Avoidant

  • Resistant

  • Disorganized

secure attachment leads to the best social and emotional development

Secure attachment is balance between exploration and closeness, the child welcomes the caregiver upon return

Avoidant attachment is independent, the child avoids the caregiver upon return

Resistant attachment is showing anger towards the caregiver upon return

Disorganized attachment is confused and inconsistent behaviors

Attachment occurs best between 6 months and 3 years

Parenting styles

  • authoritarian

  • Democratic

  • Permissive

  • Uninvolved

Authoritarian- parents are strict and expect obedience without explanation

Democratic- parents involve children in decision making and provide explanations and balance

Permissive- children make most decisions with few rules set by the parents

Uninvolved- parents are distant and uncommitted

With authoritarian parents the children may feel restricted with limited decision making

With democratic parenting children grow confident, responsible, and independent

With permissive parents children lack boundaries and struggle with self discipline

With uninvolved parents children experience emotional and developmental challenges

Socialization- learning acceptable behaviors in a culture

Identity formation is acquired through interactions

Freud’s theory of Psychosexual development

  • children are born with strong sexual urges

Phallic stage- children become aware of sexual differences

Identification- adopting the values and moral principles of the same sex parent

Erikson’s Theory of Psychosocial Development

  • emphasized social approval and interaction

  • Development lasted throughout life

Social approval- a key factor in shaping an individual’s sense of self

Role taking- children’s play that is assuming adult rules

Lawrence Kohlberg on moral reasoning with the Heinz Dilemma

Stage 1:

Obedience + Punishment

  • moral decisions based on avoiding punishment

  • rules are fixed and must followed to avoid consequences

Heinz answer- Don't steal because he could get in trouble

Stage 2:

Self-interest

  • Focused on personal gain

  • Actions based on rewards

Heinz answer- steal because it will help him and his wife

Stage 3:

Social approval

  • Decisions based on what others think

Heinz answer -

should steal - think he's cruel if not

shouldn't steal-think he's a criminal if done

Stage 4:

Law + Order

  • Laws are moral rules that must be followed

  • Less on approval, but more of maintaining order

Heinz answer-shouldn't steal because it is against the law

Stage 5:

law is fair or just

  • Laws aren't absolute

  • benefit society as a whole

Heinz answer- theft may be excused because the price is unfair

Stage 6:

Accept universal ethical rules

  • golden rule

  • Ethical principles are more important than laws

  • May sacrifice personal interests
