Psych

Front 1

experimental method

Back 1

researdcher randomly assigns participants in different conditions and ensures these conditions are identical except for the independent variable

Front 2

independent variable

Back 2

variable researcher changes or varies to see if it has an effect on a variable

Front 3

dependendent variable

Back 3

researcher measures to see if it is influenced by independent
ie:data,influenced

Front 4

random assignment

Back 4

procedure ensures every participant has an equal chance of being in any of the experimental conditions

Front 5

internal validity

Back 5

ensure nothing else besides the independent variable will affect the dependant variable, ensured by random assignment

Front 6

external validity

Back 6

extent to which the results of a study can be generalized to other situations and other people

Front 7

correlational method

Back 7

two or more variables measured and the relationship between them is assessed

Front 8

Pos. correlation

Back 8

increase value of one variable associated with increase in another

Front 9

neg. correlation

Back 9

increase in value of one variable associated with a decrease in another

Front 10

correlation bad effects

Back 10

correlation does not equal causation

Front 11

excitatory messaging

Back 11

impulses that will cause the neuron to fire/generate action potential

Front 12

inhibitory messaging

Back 12

impulses that do not fire

Front 13

lock and key mechanism

Back 13

only specific receptor site recieves specific neurotransmitters

Front 14

agonist

Back 14

mimics neurotransmitter
spider venom, sends excitatl effec, over firing, mimic effect

Front 15

antagonists

Back 15

block particular transmitters
curare, blocks ability to bind to receptor site, paralyzation

Front 16

endorphines

Back 16

body natural pain killers, neurotransmitters

Front 17

morphine/heroin

Back 17

agonist for endorphines, make feel no pain

Front 18

selective saratonien reuptake inhibitors

Back 18

prosac, blocks reuptak, makes saratonien flow into synapse gap

Front 19

brainstem

Back 19

primitive life support function, back of brain;connects to spinal chord

Front 20

thalamus

Back 20

brain's sensory switchboard, sweet/soar, light/dark

Front 21

medulla

Back 21

controls heartbeat and breathing

Front 22

cerebellum

Back 22

coordinates voluntary movement, if damaged may cause inbalance

Front 23

limbic system

Back 23

motivation, emotion, basic learning, memory

Front 24

hypothalamus

Back 24

hunger, thirst, sexual behavior, pleasure center of brain

Front 25

amygdala

Back 25

aggression and fear, same structure but incharge of oppisite feelings

Front 26

hippocampus

Back 26

explicit memory center

Front 27

cerebral cortex

Back 27

frontal lobe-speech production
temporal-hearing/speech production

Front 28

Broca's area

Back 28

controls speech muscles via the motor cortex, TA-man, could speak one word, hum, can write responses

Front 29

Wernika's Area

Back 29

interprets auditory code, grumble of words come out, know what to say but changes when start to talk

Front 30

Hemispheres

Back 30

left and right, control opposite part of body

Front 31

cut at the corpse callosum

Back 31

causes there to be no communication between hemispheres, split brain patient experiments
hemispheres:
left-lang.speech, reading
right-nonverbal, recognization

Front 32

stoop effect

Back 32

color difference: Brown, inability to turn off automatic processing

Front 33

Automatic processing

Back 33

process of information with minimal conscious awareness, Ex. drive car and talk, and drink...,
can not turn off

Front 34

Controlled processing

Back 34

process information at relatively high levels of consious awareness

Front 35

why sleep

Back 35

-general recuperation
-growth process
-info. processing
-rem rebound-spend tramendous tim in rem if deprived it

Front 36

insomnia

Back 36

trouble going to sleep

Front 37

narcolepsy

Back 37

irresistable and sudden attacks of rem sleep during day

Front 38

sleep apnea

Back 38

change from wakefulness to sleep, causes the central nervous system to stop functioning, when do fall asleep constantly awake from not breathing

Front 39

sleep walking

Back 39

occur during deep sleep stage 4

Front 40

lucid dreaming

Back 40

aware dreaming, may be able to control, can train self

Front 41

dream theory: wishfulfillment (freud)

Back 41

people are unsconsiously motivated to satisfy sexual and aggressive drives, dreams are disguised, symbolic meaning, deep meaning

Front 42

manifest content

Back 42

dream we remember

Front 43

latent

Back 43

underlying urges,conflict, needs that give rise to the dream

Front 44

dream theory:Activation-synthesis theory

Back 44

random neural signals fire in brain...., no symbolism
