Front 1

Dualism

Back 1

Belief that body and soul are separate

Front 2

Materialism

Back 2

Conciousness viewed as physical phenomenon

Proposed by Bernard Baars

Global workspace is essentially the conscious mind and acts to bring together numerous sources of information.

Front 4

Blindsight

Back 4

Ability to interact with objects while remaining consciously unaware of them. Damage to visual cortex

Front 5

Vegetative State

Back 5

Awake, shows sleep/wake cycles, not aware of self or environment. No interactions, no voluntary responses.

Front 6

Minimally Conscious State

Back 6

Condition of severely altered conciousness where there is minimal evidence of awareness. Most show some evidence of reproducible voluntary behavior.

Front 7

Brain Death

Back 7

Irreversible loss of conciousness with total loss of brain function.

Front 8

Locked-In Syndrome

Back 8

Condition in Which an individual is fully concious, but no muscles work, with the exception of the eye.

Front 9

Consequence of Basal Forebrain stimulation

Back 9

Induces Sleep

Front 10

Supreachiasmatic Nucleus

Back 10

24 hour rhythm generator

Front 11

What are the 5 stages of sleep?

Back 11

1. Slow, irregular brain waves

2. Lasts 10-20 minutes. Irregular brain scan.

3. Slow-Wave sleep

4. Deep restorative Sleep

5. REM. Increased HR/Respiration

Front 12

What is Restoration Theory?

Back 12

Belief that sleep is needed to revitalize psychological processes that keep mind and body healthy.

Front 13

Protection Theory?

Back 13

Theory that sleep holds an adaptive function, protection from predators.

Front 14

How are sleep and memory connected?

Back 14

Evidence suggests we reprocess memories when we sleep.

Front 15

Waking Brain Wave Activity

Back 15

Mostly Alpha and Beta frequency bands. High frequency, low amplitude. Alpha predominant in relaxed state

Front 16

Stage 1 brain activity

Back 16

slowing to theta activity

Front 17

Stage 4 brain activity

Back 17

Deepest sleep, delta activity

Front 18

Name for stages 2-4

Back 18

slow-wave sleep

Front 19

Characteristics of REM and associated disorders

Back 19

Beta activity (usually awake). REM atonia: muscle paralysis during REM sleep. Night terrors, restless leg syndrome, bruxism, somnambulism.

Front 20

Simple definition of Attention

Back 20

Selection of some information at the expense of others

Front 21

Conjunction Search

Back 21

Search involving looking for multiple features. Must be conducted serially.

Front 22

Singleton Search

Back 22

Can be conducted in parallel.

Front 23

Feature-Integration theory of attention

Back 23

Lines are simple objects, but attention is required to put together features for an object.

Front 24

Signal Detection Theory

Back 24

Concerned with how we perceive sights or sounds when evidence for them is weak.

Front 25

Response Bias

Back 25

A person's tendancy to say yes or no when he is not sure if stimulus is present

Front 26

Satisfaction of Search

Back 26

Once target has been found, tend to stop searching

Front 27

RSVP (Rapid, Serial Visual Perception)

Back 27

Not conscious for 1/4 second after

Front 28

Change Blindness

Back 28

Failure to detect change when vision interrupted by a saccade or obstruction.

Front 29

Inattentional Blindness

Back 29

Failure to Perceive an event when attention is diverted

Front 30

Functional Neuroimaging

Back 30

Allows investigation and manipulation of experience

Front 31

Bistable Stimuli

Back 31

Allows investigation of perception favorability
