Developmental Psychology
examines development across a lifespan
cross-sectional study
comparing a group of people in different ages in a small period of time
longitudinal study
studies the same group of individuals over a long period of time to see changes/development
nature and nurture
the influence genetics and environment has on development
continuity stages
the idea that changes occur smoothy over a set period of time in predetermined stages
discontinuity stages
the idea that developmental changes occur slowly and gradually as one interacts with their environment
trait
relatively consistent pattern of behavior
stability in traits
traits that dont change; eg. kids who are undiciplined are more likely to get in trouble with the law when they’re older
change in traits
traits that change overtime; eg. children start getting brave aound age 4
prenatal development: germinal stage
from 0 - 2 weeks of fertilization; the fertilization/formation of the zygote, zygote goes down fallopian tube, implants into the uterine wall
prenatal development: embryonic stage
from 2 - 8 weeks; major systems begin to develop; eg. heart, brain, limbs placenta transfers nutrients and oxygen into the embryo
prenatal development: fetal stage
from 9 weeks - birth: fetus continues to grow and gains weight
teratogens
agents such as viruses and drugs that can harm the embryo; eg. alcohol, nicotine, marijuana
fetal alchohol syndrome (FAS)
caused by alcohol’s epigenetic effects that leave chemical marks on DNA, causes genes to switch on/off and makes physical/cognitive defects
adaptive reflexes
rooting reflex: the cheek/side of face is touched → the baby turns their head to the side, opens their mouth
startle reflex: loud noise → arms/legs will spring out and the baby will cry
grasping reflex: object touches baby’s palm→ the baby will grasp on it tightly
habituation
increased stimulation causes less interest; eg. the more familiar the baby is with the stimuli, the more bored they become
social responsiveness (babies are developing this)
infants are responsive to things like:
human voices
face-;like images
objects from an 8-12 in distance (equal to the distance between a mom’s eyes and a baby’s eyes while nursing)
mother’s smell
maturation
biological growth processes that enable orderly changes in behavior that are relatively uninfluenced by behavior
frontal lobe growth
from 3 - 6 years; enables rational planning and facilitates controlling
brain’s association areas
happens during puberty; happens in parietal/temporal lobe, aids in thinking/memory, language, and problem solving, maintains pathways supporting agility and control
pruning process
synaptic process that shuts down unused links; eg. forgetting how to play piano due to long periods of not playing piano
neuroplasticity
neural tissue is constantly changing due to new experiences; eg. when learning how to ride a bike, the brain forms connections to things like balance
fine motor skills
precise movement in building muscles of the body; eg. grasping, holding, pointing, and drawing
gross motor skills
involving large muscles in full body movement; eg. sitting, crawling, walking, jumping
infantile amnesia
the inability to recall memories from before age 4; weakens as children occur development in the frontal lobe (hippocampus)
lifespan perspective
when developmental psychologists take a look into how our lives influence us as an individual (infancy, childhood, teen years, adulthood)
maturation
the experiences we face and hold on to change who we are and how we live
adolescence
years spent morphing from child into adult; transition period that begins with puberty
cultural awareness (in regards to development)
culture does have an affect on the stages of life and how we develop
primary sex characteristics
innate; sex organs that are developed and presented at birth
secondary sex characteristics
traits that develop throughout puberty
puberty
a period of sexual maturation which a person becomes able of sexually reproducing
physical changes for women during puberty
breasts start to grow and menarche (first menstrual cycle) happens
physical changes for men during puberty
voice drops and spermarche (start of sperm development) happens
adolescent growth spurt
a significant physical change when hormones increase the height/weight of an individual
menopause
end of menstruation; biological changes as a woman’s ability to reproduce declines; causes depression/anxiety, hot flashes/night sweats, trouble speaking
what happens to brains as we get older
vision declines; becomes more susceptible to diseases; cognitive decline
Jean Piaget
had a theory about 4 stages of cognitive development
sensorimotor stage

object permanence & stranger anxiety form
object permanence
the ability to know objects exist when they aren’t sensed
stranger anxiety
not recognizing new people because they don’t fit into schemas of people they already know
pre-operational stage
from 2 - 7 years; when the child starts to use their mouth to speak, but still not able to do mental operations
develops animism, egocentrism, and centration
reversibility
the ability to reverse operations; eg. if i have a sister, then my sister has a sister
egocentrism
difficulty perceiving the world from another’s perspective
animism
the belief that inanimate objects are alive and have feelings
concrete operational stage
from 7 - 11 years; when children start performing mental operations about concrete events and enables them to think logically
develops conservation and reversibility
conservation
recognizing that a thing hasn’t changed when it’s been physically altered
formal operational stage
from 12+ years; systematic reasoning, when reasoning expands to abstract and hypothetical
Lev Vygotsky
had a theory about how one’s social/cultural experiences affects cognitive development
social-cultural theory
the theory that cognitive development doesn’t go through a set number of stages, but occurs naturally as one interacts with their environment
scaffolding
giving children support for learning until they’re able to do it alone
zone of proximal development
the difference between what a child can do without help from the environment
theory of mind
the ability to understand others, thoughts, beliefs, feelings, etc. are different from your own; recognizing that everyone is their own person
terminal decline
occurs when cognitive decline accelerates when approaching the last 3 -4 years of life
prospective memory
the ability to remember to do future events

phonemes
smallest sound units in a language; don’t always have meaning
morphemes
smallest sound units in a language that does have meaning
grammar
the rules of language
natural talent
the idea that infants have the natural capacity to learn language, but in order to do so, they need interaction

semantics
how meaning is stored in the mind; the meanings of words, signs, symbols, and the phrases that represent them
syntax
the cognitive capacity of human beings that allows us to connect linguistic meaning with linguistic form; eg. understanding what “the boy kicked the ball” means, because it follows a subject-verb-object word order

Erik Erikson’s Psychological Stages of Development
8 stages of development, each with a different issue to face
infancy (Erik Erikson)
from 0 - 1 years; trust vs mistrust; building basic trust, requires a reliable and consistent response from parent
toddlerhood (Erik Erikson)
from 1 - 3 years; autonomy vs shame/doubt; toddlers learn to exercise their will and do things by themselves, they’re on their way to becoming unique individuals; synonymous with self-esteem
preschool (Erik Erikson)
from 3 - 6 years; initiative vs guilt; toddlers start gaining autonomy and make decisions by themselves
schooling years (Erik Erikson)
from 6 years to puberty; competence/industry and inferiority; develops confidence, becomes more industrious (learning to do basic skills, writing, bouncing a ball, etc.)
adolescence (Erik Erikson)
from teen years - 20s; trying different roles (music, values, sexual orientation), the main goal of adolescence is to solidify one’s sense of self
