Final Notecards Flashcards
Refers to the questions of how biological (nature) and environmental (nurture) forces impact development
nature nurture issue
Development is _______
Development is _______ and ________
Development is highly ______
Development is affected by multiple ______forces
lifelong multidimensional multidirectional plastic interacting
allows inferences about cause and effect because researchers use random assignment of participants into two or more conditions/groups
experimental
groups of people differing in ages are studied at the same point in time or at different points in time
cross sectional
participants are studied repeatedly, and changes are noted as they get older
longitudinal
: several similar cross-sectional or longitudinal studies are conducted at varying times
sequential
the largest portion of the mind, is the source of biological needs and desires
Always wants to lash out in childlike ways, like throwing a temper tantrum if your parent wont let you eat ice cream after school
ID
the conscious, rational part of personality, redirects the id’s impulses in socially acceptable ways
Compromises in socially acceptable ways, like promising a parent that if you are allowed to eat ice cream after school, you will eat double the normal amount of veggies at dinner time
ego
the conscience, represents the values of society to which one must conform
Makes one aware of what is moral and immoral in the eyes of society, like knowing its not acceptable to hit a playmate to get his toy
superego
natural stimulus that produces a reflex
unconditioned stimulus
natural reflex to some natural stimulus
unconditioned response
– stimulus that, after being paired with an unconditioned stimulus, now elicits a response similar to a reflex
conditioned stimulus
the response to a conditioned stimulus
conditioned response
always increases the occurrence of a behavior
reinforcer
something positive happens every time the target behavior occurs
You get a cookie every time you put your dishes in the dishwasher after dinner, so you will put your dishes away more frequently
positive reinforcer
removing something negative every time the behavior occurs
When you have a headache, you take an Advil which makes the pain go away, thus you will take an Advil every time you have a headache
negative reinforcer
always decreases the occurrence of a behavior
punishment
taking away something positive every time the behavior occurs
When you don’t put your cloths in the hamper, your mom takes a privilege away so you will stop leaving cloths on the floor
negative punishment
presenting something negative every time the behavior occurs
You are spanked every time you throw a tantrum in public so you will stop acting out in public
positive punishment
segment of DNA along the length of the chromosome
gene
Each form of a gene is called an
allele
the proportion of the differences in a trait among a group of people that is due to genetic differences among these people
heritability
our genes influence the environments to which we are exposed
genetic environment correlation
when our disposition actively affects the sorts of environments we find ourselves in
Ex. Athletic well-coordinated child may play sports, child with enhanced sense of melody and rhythm may play a musical instrument
active genetic/environmental correlation
any environmental agent that causes a birth defect
teratogen
How severely a teratogen affects the developing baby depends on ALL 3 of these:
the _____ of exposure or dose of the teratogen
the _______ of the exposure
the _______ of the embryo or fetus
length
timing
genetic makeup
If a mother does not get adequate nutrition during pregnancy and does not gain the appropriate amount of weight (25-30 lbs)
The most likely negative outcome for the baby is __________
mental impairments
are generational changes
Ex. In North America, people get taller with each generation
secular trends
mastery of motor skills involves acquiring increasingly complex systems of action
When motor skills blend together, each cooperating with others to produce more effective ways of exploring and controlling the environment
Ex. Control of the head and upper chest combine into sitting
Ex. Standing, stepping, and improved upright posture control combine into walking
Ex. A 10 month-old realizes that rolling over doesn’t get him very far, but then figures out how to crawl across a room to get a favorite toy
dynamic systems perspective
- The work that the heart is able to perform beyond that required of it under ordinary circumstances
Decreases in reserve capacity occur in late adulthood
This means that an elderly person’s maximum heart rate is lower
Ex. Even if a 60 year-old is in top shape, his/her maximum heart rated during exercise is still going to be lower than it was in his/her 20s
The heart just cant beat as fast, meaning ____________
cardiac reserve capacity
decreased reserve capacity
Basically suggests that certain human abilities are innate (that we are born with them already in place)
So if a parent believes their newborn already has the capacity to understand certain things (like judging distance, perceiving if something moving towards or away, understanding of language, etc.), this would reflect the
nativist perspective
Very young infants are sensitive to all speech/language sounds
With age, we become more sensitive to sounds that are relevant in our own language and less sensitive to sounds that are irrelevant
Ex. Young infants can detect differences in vowel sounds of different languages that sound the same to older children and adults
But with age, we lose this ability as we become focused on learning our own language
speech perception
occurs when sensory receptors change their sensitivity to a stimulus
sensory adaptiation
- adaptation to reduced light intensity
Like going from a well lit area to a darker area
The time it takes to adapt to changes increases as we get older
Ex. When an elderly person turns off the light in their living room, and has more trouble finding their way to the bedroom in the dark than they used to, this indicates ________________
dark adaptation
slower dark adaptation
