Q3: Development Flashcards
developmental stages
prenatal, childhood, adolescence, adulthood
prenatal period
time from conception to birth. three stages: germinal, embryonic, and fetal
germinal
0-2 weeks, sperm fertilizes egg, implantation in uterus
embryonic
3-8 weeks, organ systems begin to develop
fetal
9wks-9months, organs continue to grow and start functioning, arms and legs move spontaneously
influences on prenatal development
maternal factors: alcohol, nutrition, smoking, psychoactive drugs, environmental toxins.
paternal factors: quality of sperm
folic acid
critical for bone development and growth. spina bifida, cleft palate.
childhood development
motor, cognitive, gender identity, social attachments
motor development
babies are born with a range of reflexes: rooting, eye blink, sucking, moro, palmar grasp, babinski reflex.
sequence of motor milestones: rolling over, sitting unsupported, crawl, walk
cognitive development
age related changes in learning, memory, perception, attention, thinking, and problem solving
Jean Piaget
fascinated by children having similar wrong answers on IQ tests. proposed that children’s reasoning develops in a series of stages.
Intelligence (Piaget)
- schemas, 2. process/functions (memory, processing speed)
schemas
include assimilation and accommodation
assimilation
knowledge/experience fitting with a schema
accommodation
modifying a schema to fit new knowledge
piaget’s stages of cognitive development
- sensorimotor, 2. preoperational, 3. concrete operations, 4. formal operations
sensorimotor
experiencing the world through senses and actions (looking, touching, mouthing, grasping).
object permanence, stranger anxiety, imitation, cause-and-effect
