Terms | Definitions |
|---|---|
 consciousness | our awareness of ourselves and our environment |
| circadian rhythm | the biological clock; regular bodily rhythms that occur on a 24-hour cycle |
| REM sleep | rapid eye movement sleep, 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. |
| hallucinations | false sensory experiences, such as seeing something in the absence of an external visual stimulus |
| narcolepsy | a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may laps directly into REM sleep often at inopportune times |
| sleep apnea | a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings |
| manifest content | According to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content) |
| latent content | according to Freud, the underlying meaning of a dream (as distinct from its manifest content). Freud believed that a dream's latent content functions as a safety valve |
| hypnosis | a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur |
| depressants | drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions |
| opiates | opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety |
| stimulants | drugs (such as caffeine, nicotine, and the more powerful amphetamines, cocaine, and Ecstasy) that excite neural activity and speed up body functions. |
| hallucinogens | psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input |
| activation synthesis hypothesis | REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories |
