Exam 3 Flashcards
Continuity
The continuation of life
Baby, individual, adult
Stages
Biologist stand point more specific to periods in life
Infant, toddler, preadolescent, adolescent
Zygote
1 sperm and 1 egg together
How many eggs will mature in a female
1 in 5,000
When do men start producing sperm
Puberty
Will produce up to 1,000/second at peak
Differentiation
Where, after 1 cell division (about 100) cells are dorm into the specific body cells- heart, cheek, lung, etc
What areas does developmental psych study
Physical, cognitive, and social
Recognition memory
Learn to recognize and certain stimuli so a certain reaction can be made
Ex- a baby learns to react to a mothers voice
What can compromise recognition memory development
Smoking
Alcohol
FAS
Caused by drinking in first trimester and causes facial defects
Symptoms of FAS
Wide set eyes Philtrum missing Thin upper lip Flat bridge of the nose Small ears
Root reflex
Turn the way the cheek is stroked
Suck reflex
Suck the way the head is turned
Grasp reflex
Grasp a finger when out into hand
Babinski reflex
Strike bottom of foot, toes spread out
Startle reflex
Scare easily
Step reflex
Hold arms up when feet touch floor the reflex is pushing up
Visual habituation
How babies learn
How do babies learn
Vision test that tracks fovea when an object is shown then taken away and shown with another object, they look at the first object
Infantile amnesia
Often don’t recall events from less than 3 years because the brain (hippocampus) isn’t mature at birth, when it matures we are not able to remember things from before maturity
What are the 4 stages of Piagets stage theory
Birth
Sensorimotor
Pre operational
Concrete operational
Piagets theory birth
Birth to 2 years
Piagets theory sensorimotor
Coordination of sensory input and motor responses
Piagets theory preoperational
Start to think about things- symbols, hierarchies
Learn language not logic
Ego central- everything is about me
Concrete operational
Logic thinking- learn that there isn’t an answer for everything
Explain attachment/stranger anxiety
Attachment is based on comfort not food
Based on Charlow’s monkey work
What can happen without proper comfort as a child
Low IQ, increase anxiety/aggression, poor social skills
What happens I puberty
Desire to make own decisions, and develop personality
What does the prefrontal cortex have to do with puberty
It is not full developed until after puberty. So people will do things without having an explanation for it. If it isn’t fully developed, it won’t inhibit bad behavior and impulse control.

Has to do with the trolley and bridge dilemma
List changes in adulthood

Menopause
Viagra- ED
Digestion- Can keep weight off

Neurofibulary tangles, that are supposed to be in lines, get messed up in hippocampus
Beta amyloid plaques
Garbage in the brain- dying neurons that don’t get cleaned out
What will happen in 2030
65+ will be 25% of the population and we will have to pay for them
Cognition
Mental activities associated with thinking, knowing, remembering, and communicating
Concepts,
Mental grouping of similar ideas, objects, or people, but all have differences- simplifies thinking
Ex concept of a student- hard working, studious individual that goes to school
Strategies to facilitate thinking
Trial and error
Algorithms
Heuristics
Insight
What is insight
Aha moment when everything clicks
What is trial and error
Operant conditioning- do you get a reward or not
Heuristics
Simpler, vague, but more flexible than algorithms
Algorithms
Step by step procedure that guarantees an outcome
Only gets the correct outcome when everything is don’t correctly
