front 1 consciousness | back 1 our subjective awareness of ourselves and our environment |
front 2 cognitive neuroscience | back 2 the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language) |
front 3 selective attention | back 3 the focusing of conscious awareness on a particular stimulus |
front 4 inattentional blindness | back 4 failing to see visible objects when our attention is directed elsewhere |
front 5 change blindness | back 5 failing to notice changes in the environment; a form of inattentional blindness |
front 6 dual processing | back 6 the principle that information is often simultaneously processed on separate conscious and unconscious tracks |
front 7 blindsight | back 7 a condition in which a person can respond to a visual stimulus without consciously experiencing it |
front 8 parallel processing | back 8 processing many aspects of a problem simultaneously; the brain's natural mode of information processing for many functions |
front 9 sequential processing | back 9 processing one aspect of a problem at a time; generally used to process new information or to solve difficult problems |
front 10 sleep | back 10 a periodic, natural loss of consciousness- as distinct from unconsciousness resulting for a coma, general anesthesia, or hibernation |
front 11 circadian rhythm | back 11 our biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24 hour cycle |
front 12 REM Sleep | back 12 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 |
front 13 alpha waves | back 13 the relatively slow brain waves of a relaxed, awake state |
front 14 hallucinations | back 14 false sensory experiences, such as seeing something in the absence of an external visual stimulus |
front 15 delta waves | back 15 the large, slow brain waves associated with deep sleep |
front 16 suprachiasmatic nucleus | back 16 a pair of cell clusters in the hypothalamus that controls circadian rhythm. In response to light, the SCN causes the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness |
front 17 insomnia | back 17 recurring problems in falling or staying asleep |
front 18 narcolepsy | back 18 a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times |
front 19 sleep apnea | back 19 a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings |
front 20 night terrors | back 20 a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during NREM-3 sleep, within two or three hours of falling asleep, and are rarely remembered |
front 21 dream | back 21 a sequence of images, emotions, and thoughts passing through a sleeping person's mind |
front 22 manifest content | back 22 according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content) |
front 23 latent content | back 23 according to Freud, the underlying meaning of a dream (as distinct from its manifest content) |
front 24 REM rebound | back 24 the tendency for REM sleep to increase following REM sleep deprivation |
