studies physical, cognitive, and social development throughout the lifespan
developmental psychology
comparing people of different ages at the same time
cross-sectional studies
follows and retests same people over time
longitudinal studies
a major issue exploring how genetics interacts with our experiences to influence out development
Nature and Nurture
a major issue exploring what parts of our development are gradual and what parts of our development change abruptly in separate stages
Continuity and Stages
a major issue which explores which of our traits persistant through life and how we change with age
Stability and Change

placenta
the developing human organism from 9 weeks after conception to birth

leaves chemical marks on DNA that switch genes abnormally on or off
can leave scars that may increase vulnerability to stress or addictions
epigenetic effect
refers to automatic reflexes
include reflexes such as sucking and grasping
concept of how babies can tell you a lot
“Babies come with apps preloaded”
decreasing responsiveness with repeated stimulation
habituation

example of cloth on a toy
young infants lack this
object permanence
until about age 6 or 7
child learns to use language but does not yet comprehend the mental operations of concrete logic such as imagining an action and mentally reversing it
ex. 2 +2 = 4
4 - 2 = 2
