Module 7 And Module 8

Front 1

circadian rhythm

Back 1

the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle

Front 2

REM (Rapid Eye Movement) sleep

Back 2

a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep because the muscles are relaxed (except for minor twitches) but other body systems are active

Front 3

alpha waves

Back 3

the relatively slow brain waves of a relaxed, awake state

Front 4

sleep

Back 4

periodic, natural, reversible loss of consciousness - as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation

Front 5

hallucinations

Back 5

false sensory experiences, such as seeing something in the absence of an external visual stimulus.

Front 6

delta waves

Back 6

the large, slow brain waves associated with deep sleep

Front 7

insomnia

Back 7

recurring problems in falling or staying asleep

Front 8

narcolepsy

Back 8

a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times

Front 9

sleep apnea

Back 9

a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings

Front 10

night terrors

Back 10

a sleep disorder characterized by high arousal and an appearance of being terrified; occur during Stage 4 sleep, within 2-3 hours of falling asleep and are seldom remembered

Front 11

dream

Back 11

sequence of images, emotions and thoughts passing through a person's mind. Notable for hallucinatory imagery, discontinuities and incongruities, and for dreamer's delusional acceptance of the content and later difficulty remembering it.

Front 12

manifest content

Back 12

according to Freud, the remembered story line of a dream (as distinct from latent, or hidden content)

Front 13

latent content

Back 13

according to Freud, the underlying meaning of a dream (as distinct from its manifest content)

Front 14

Freud's wish fulfillment theory

Back 14

theory that dreams provide a "psychic safety valve" expressing otherwise unacceptable feelings. Include manifest and latent content

Front 15

information processing theory

Back 15

theory that dreams help us sort out the day's events and consolidate our memories

Front 16

physiological function theory

Back 16

theory that regular brain stimulation from REM sleep may help develop and preserve neural pathways

Front 17

activation-synthesis theory

Back 17

theory that REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories

Front 18

cognitive development

Back 18

theory that dream content reflects dreamers' cognitive development-their knowledge and understanding

Front 19

REM rebound

Back 19

the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakening during REM sleep)

Front 20

consciousness

Back 20

our awareness of ourselves and our environment

Front 21

cognitive neuroscience

Back 21

the interdisciplinary study of the brain activity linked with cognition (includes perception, thinking, memory, and language)

Front 22

dual processing

Back 22

the principle that information is often simultaneously processed on separate conscious and unconscious tracks

Front 23

selective attention

Back 23

the focusing of conscious awareness on a particular stimulus

Front 24

inattentional blindness

Back 24

failing to see visible objects when our attention is directed elsewhere

Front 25

change blindness

Back 25

failing to notice changes in the environment
