Developmental Flashcards
(130 cards)
Developmental psychology
examines our physical, cognitive and social development across the life span, with focus on three major issues:
- Nature and nurture
- Continuity and stages
- Stability and change
Stage theories
contribute a developmental perspective on the whole life span, by suggesting how people of one age think and act differently when they arrive at a later age
-
For example:
- out of control 3 year olds were more likely to become troubled teens
- wildest smilers in childhood photos- most likely to enjoy enduring marriages
- responsible primary school students outlive out of control classmates
zygote
- fertilized egg enters a 2 week period of rapid cell division and develops into and embryo
Embryo
- the developing human organism from about 2 weeks after fertilization through the second month
Fetus
- the developing human organism from 9 weeks after conception
- At each prenatal stage, genetic and environmental factors affect our deelopment.
- Fetuses prefer hearing their mothers native language- learning of language begins in the womb.
teratogens
- agents such as viruses and drugs, can damage an embryo or fetus.
EXAMPLE: when pregnant rats drank alcohol their young offspring later displayed a liking for alcohol’s taste and odor.
Fetal alcohol syndrome
- physical and cognitive abnormalities in children caused by pregnant womans heavy drinking.
- EXAMPLE- in severe cases, signs include a small, out of proportion ead and abnormal facial features
effects of stress during pregnancy
- If a pregnant woman experiences extreme stress, the stress hormones flooding her body may indicate a survival threat to the fetus and produce an earlier delivery.
- can result in health problems such as hypertension, heart disease, obesity, and psychiatric disorders
Habituation
- decreasing responsiveness with repeated stimulation
- EXAMPLE: As infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner.
Infant brain development
in humans the brain is immature at birth. As the child matures, the neural networks grow increasingly complex
The brains association areas
- those linked with thinking, memory, and language- were the lst cortical areas to develop.
Maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.
cognition
all the mental activities associated with thinking, knowing , remembering and communicating.
Schema
a concept or framework that organizes and interprets information
assimilation
we interpret & store information using existing schemas
Accommodation
we adjust existing schemas or create new ones that account for the new knowledge.
Object permanence
the awareness that things continue to exist even when not perceived
Sensorimotor stage
in piaget’s theory, the stage (from birth to nearly 2 years of age ) during which infants know the world mostly in terms of their sensory impressions and motor activities
Cognition
refers to all the mental activities associated with thinking, knowing
Piaget’s Theory
The theory extends from the first days of infancy through adolescence & examines diverse topics in cognitive development such as memory, understanding of other people’s perspectives, problem solving & more
Observations of infants
consist of observing how the infant responds in their natural environment. No interventions are made
Piaget’s Basic Assumptions
- Children are mentally active from birth.
- Metaphor of a “child as scientist”, that generates hypotheses, performs experiments & draws conclusions from observations.
- Children are intrinsically motivated to learn & develop & are not dependent on external rewards or punishments that are given by adults.
- Children learn from their own experiences & are not dependent on adults’ instructions.
New experiences can be processed through
- 1. Assimilation: we interpret & store information using existing schemas; or
- 2. Accommodation*: we adjust existing schemas or create new ones that account for the new knowledge.
- EX: when children drop stuff they discover gravity, and balloon they are also learning
