Chapter 9 Flashcards
Developmental Psychology Studies
How individuals develop:
- Cognitively
- Physically
- Socially
Nature Vs. Nurture
How genetics influence our experiences and development
Zygote
Fertilized egg
Less than half zygotes survive
the first two weeks
Following cell division the zygote becomes an
embryo
9 weeks after conception the embryo becomes a
fetus
Placenta has
Formed at the zygotes outer cells and attached to the uterine wall
Placenta is responsible
Transfers nutrients and oxygen from the mother to the fetus; and screen potentially harmful substances
Teratogens
chemicals/viruses which may cause harm to prenatal development
fetal alcohol syndrome
physical/cognitive abnormalities caused by pregnant mother’s heavy drinking
habituation
Decrease in infants response with repetition of same stimulus
Habituation results in infants interest to
fade resulting in them looking away
Infants focus first on
the face not the body
Human brains are
immature at birth
Association areas are the
last cortical areas to develop
Association areas:
thinking, memory, and language
maturation
growth process enabling orderly changes in behavior
maturation is uninfluenced
by experience
cognition
mental activities associated with: thinking, knowing, remembering and communicating
back-to-sleep position
Placing babies on their backs to sleep to avoid a smothering crib death
genes play a major role in
motor development
infantile amnesia
memories prior to age 3 were not remembered
Learning may be present even at age
3 months
schema
A concept/mental mold interprets information
Assimilation
Interpreingt new experiences into existing schemas
Accomodation
Adapting our current understandings/schemas to incorporate new information
sensorimotor stage
babies take in the world through senses and actions- (Piaget)
object permanence
awareness that things continue to exist even when not perceived
preoperational stage
Child learns language but does not understand mental logic operations- Piaget
Conservation
Principle that properties such as mass, volume and number remain despite object form changing- Piaget
egocentrism
child’s difficult to view something the same as another’s perception- piaget
theory of mind
infer other’s mental states: feelings, perceptions and thoughts they may predict
concrete operational stage occurs in ages
Around 6 to 11
Concrete operational stage allows
individuals to grasp conservation and to think logically regarding events and mental operations- Piaget
formal operational stage
systematical reasoning; if this then that- abstract concepts- Piaget
Formal operational stage typically beings at
age 12
Autism symptoms
deficient, communication, social interaction and understanding of others’ states of mind
stranger anxiety
fear of strangers displayed by infants
stranger anxiety is displayed at
8 months
attachment
emotional tie often with caregiver
critical period occurs in
animals
critical period
time after birth where stimuli occur to result in proper devlopment
