Introductory To Psychology Clep Set 2

Front 1

Long fibers that pass info. along to other nerve cells, to glands, or to muscles.

Back 1

Axons

Front 2

A fatty tissue that surrounds the axon and accelerates tranmission of info.

Back 2

Myelin sheath.

Front 3

Electrically charged atoms.

Back 3

Ions

Front 4

Maintained because the axon's membrane won't let positive ions into the cell unless the cell receives a signal from the dendrites.

Agonists

Front 9

Drugs that block.

Back 9

Antagonists

Front 10

Includes the sensory and motor neurons.

Back 10

Peripheral nervous system.

Back 11

Somatic nervous system

Front 12

Regulates the body's internal environment.

Back 12

Autonomic nervous system

Front 13

Prepares you for action

Controls breathing and heartbeat.

Back 15

Brainstem

Front 16

Receives info. about touch, taste, sight, and hearing

Back 16

Thalamus

Front 17

Controls arousal and sleep

Back 17

Reticular formation

Front 18

Coordination of voluntary movement

Back 18

Cerebellum

Front 19

Processes memory

Back 19

Hippocampus

Front 20

Influences fear and anger

Back 20

Amygdala

Front 21

Influences hunger, thirst, and sexual behavior

Back 21

Hypothalamus

Front 22

Influences the release of hormones from other glands

Back 22

Pituitary gland

Front 23

Motor, cognitive, and sensory processes.

Back 23

Cerebral cortex

Front 24

Play a part in coordinating movement and in higher level thinking

Back 24

Frontal lobes

Front 25

Where is the Broca's area and what does it affect?

Back 25

Frontal lobe, speech speed.

Front 26

Where is the Wernicke's area and what does it affect?

Back 26

Frontal lobe, understanding.

Front 27

Sensor of touch.

Back 27

Pariental Lobes

Front 28

Involved in hearing

Back 28

Temporal lobes

Front 29

Areas involved in vision.

Back 29

Occipital lobes.

Front 30

Area of psychology that addresses the topic of sensation.

Back 30

Psychophysics.

Front 31

Minimum stimulation needed for a given person to detect a given stimulus.

Back 31

Absolute threshold.

Front 32

Smallest difference a person can detect.

Back 32

Just noticeable difference (difference threshold)

Front 33

Threshold increases in proportion to the intensity or magnitude of the stimuli.

Back 33

Weber's Law

Front 34

Predisposes us to attend to stimuli that matter to us and not attend to stimuli that don't.

Back 34

Sensory Adaptation

Front 35

Illustrates that our ideas about reality have to be chosen, organized, and interpreted, not simply detected.

Back 35

Selective attention

Front 36

Shows that the mind fills in the gaps in our sensations.
