Development Flashcards
Developmental Psychology
Study of continuity and change across the life span of
3 prenatal stages
Germinal Stage (2-week period) Embryonic Stage (2nd - 8th week) Fetal Stage: (9th week to birth)
Womb
Environment that affects unborn baby
Placenta
Organ that links bloodstream from mother to unborn baby - exchanges materials (food, nutrients, water, drugs, alcohol, etc.)
Teratogens
Drugs and viruses that get passed on from mother that impairs the process of development
Fetal Alcohol Syndrome (FAS)
Developmental disorder that stems from heavy alcohol during pregnancy
Infancy
Stage of development between 18-24 months
Newborn Developments
- Can only see things 8-12 inches away
- Can see specific shapes
- Can mimic facial expressions
Motor development
Emergence of ability to execute physical action
Motor reflexes
Specific patterns of movement that are triggered by specific patterns of sensory stimulation
Cephalocaudal Rule
“Top-to-bottom” : Moves head first and then works towards feet
Proximodistal Rule
“Inside-to-outside” : Moves arms and legs first then hands/fingers and toes
Cognitive Development
The ability to think and understand
Jean Piaget (1896-1980)
- Believes there are 4 stages of cognitive development in infancy
1st Stage of Infancy: Sensorimotor (birth-2 years)
Acquiring information by sensing it and moving around
Schemas
Theories and models of how the world works
Assimilation
When infants apply schemas into real life situations
Accommodation
When infants revise their schemas when gained new information
Object Permanence
Idea that objects continue to exist even when they’re not visible
2nd Stage of Infancy: Preoperational Stage (2-6 years)
Children have a preliminary understanding of the physical world
3rd Stage of Infancy: Concrete Operational Stage (6-11 years)
Children learn how various actions or operations can affect or transform concrete objects
4th Stage of Infancy: Formal Operational Stage (11 years +)
Children can solve nonphysical problems: abstract thinking
Egocentrism
Failure to understand that the world appears different to different observers (happens in Preoperational stage).
False-belief task
Young children fail to realize that other people don’t see or know what they know
Desires and Emotions
Children have difficulty understanding different emotions and reactions of others, until about 6 years of age
Theory of Mind
Understanding the mind produces representations of the world and that these representations guide behavior (playing pretend)
Criticisms of Piaget’s theory:
Children don’t go from one stage to another, there are overlaps of the stages
Lev Vygotsky
Believes children develop through interactions with members of their own culture
Joint Attention:
Ability to focus on what another person is focused on
Social Referencing:
Ability to use another person’s reactions as information about how to think about the world
Imitation:
Ability to do what another person does
Harry Harlow (1905-1981)
Conducted attachment experiments with baby rhesus monkeys
- Developed behavioral abnormalities
- Incapable of communicating/learning
- Incapable of normal sexual behavior
