Cognitive Psychology (Memory)

Front 1

action potential

Back 1

The cell fires - producting an action potential - a signal that moves down its axon and could potentially cause the next cell to fire.

Front 2

axon

Back 2

transmits signal away from cell body toward another

Front 3

attention

Back 3

the ability to selectively choose some stimuli for processing and ignore others

Front 4

cerebellum

Back 4

largest area of hindbrain

Front 5

Broca's area

Back 5

left frontal lobe - damage causes nonfluent aphasia.
can't produce speech

Front 6

wernicke's area

Back 6

damage causes fluent aphasia.
can produce speech but doesn't make sense

Front 7

central executive

Back 7

director of working memory. needed for analysis

Front 8

cognitive psychology

Back 8

scientific study of knowledge. Empirical investigation of mental processes and brain structures in acquiring perception, attention, memory, language, knowledge, and decision making.

Front 9

dendrites

Back 9

part of neuron that detect incoming signal

Front 10

dependant variable

Back 10

variable that the independant variable is compared to.

Front 11

EEG

Back 11

cap that vecords voltage changes occuring in scalp that reflect activity in brain underneath

Front 12

heuristic

Back 12

problem solving shortcuts

Front 13

hippocampus

Back 13

involved in creation of long-term memory

Front 14

hypothalamus

Back 14

base of forebrain; control of motivated behaviors - basic needs

Front 15

iconic memory

Back 15

visual input

Front 16

inattentional blindness

Back 16

not being able to see something right in front of you because you attending to another stimulus

Front 17

independent variables

Back 17

variable that is manipulated

Front 18

limbic system

Back 18

structures important for learning and memory

Front 19

long term memory

Back 19

storage system in which we hold all our knowledge and memories. contains memories that are not currently activated.

Front 20

modal model of the mind

Back 20

sees the mind as an information processing unit

Front 21

neuropsychology

Back 21

branch of psychology concerneed with relation between various forms of brain dysfunctiona nd various aspects of mental functioning

Front 22

neurotransmitter

Back 22

chemical released by neurons in order to stimulate adjacent neurons

Front 23

occipital lobe

Back 23

visual projection area

Front 24

parietal lobe

Back 24

primary sensory projection areas and curcuits crucial for control of attention

Front 25

retrieval

Back 25

locating info in memory and activating for use

Front 26

selective attention

Back 26

skill through which one focuses on one input or one task while ignoring other stimuli that are also on the scene.

Front 27

sensory memory

Back 27

holds onto input in "raw" sensory form - iconic memory for visual and echoic memory for auditory input

Front 28

short-term memory

Back 28

also known as working memory

Front 29

Stroop interference effect

Back 29

automaticity in which people asked to name color of ink instead of word itself. usually it is very difficult to filter out the word.

Front 30

synapse

Back 30

area that includes the presynaptic membrane of one neuron, teh postsynaptic membrane of another neuron, and the tine gap between them.

Front 31

temporal lobe

Back 31

primary auditory projection area, wernicke's area, and the amygdala and hippocampus

Front 32

thalamus

Back 32

lower portion of forebreain serves as a realy and integreation center for sensory info

Front 33

working memory

Back 33

storage system in which info is held while that info is being worked on. information is held here via active processes
