| Question | Answer |
| What is the cognitive theory? | Dream content reflects dreamer's cognitive development-their knowledge and understanding |
| What is the activation-synthesis theory? | REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories |
| What is the physiological function? | Regular brain stimulation from REM sleep may help develop and preserve neural pathways. |
| What is the information-processing theory? | Dreams help us sort out the day's events and consolidate our memories |
| What is Freuds' wish fulfillment theory? | Dreams provide a psyhic saftey valve--expressing otherwise unacceptable feelings; contain manifest content and a deeper layer of latent content-a hidden meanign |
| What is REM rebound? | the tendency for REM sleep to increase following REM sleep deprivation |
| During sleep rapid eye movements allows for...? | liquid behind the cornea to stir; this delivers fresh oxygen to corneal cells, preventing them from suffocation. |
| What is latent content? | according to Frud, the underlying meaning of a dream. |
| What are the proposed explanations for why we dream? | To satisfy our own wishes, to file away memories, to develop and perserve neural pathways, to make sense of neural static, to reflect cognitive development. |
| What is manifest content? | According to Freud, the remembered story line of a dream |
| What is a dream? | a sequence of images, emotions, and thoughts passing trhough a sleeping person's mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer's delusional accpentance of the content and later difficulties remembering it. |
| When is it possible to recount a dream? | If you awaken someone during or within 3 minutes after a REM sleep period. |
| When do dreams occur | IN REM sleep |
| What are night terrors? | A Sleep disorder characterized by high arousal and an apperance of being terrified; unlike nightmares, night terrors occur during stage 4 sleep, within 2-4 hours of falling asleep and are seldom remembered. |
| What is sleep apnea? | A sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings. |
| What is narcolepsy? | A sleep disorder characterized by uncontrollable sleep attacks. The sufferer may laps directly into REM sleep, often at inopportune times. |
| What is insomnia? | Reoccuring problems in falling or staying asleep. |
| What are the symptoms of someone who is sleepless and suffering? | Depressed immune system, impaired concentration, and greater vulnerability to accidents. |
| How often does the sleep cycle repeat itself? | Every 90 min |
| What is the moment of sleep? | When we seem unaware of the moment we fall into sleep, but someone eavesdropping on our brain waves could tell. |
| What are aspects of REM sleep? | heart rate rising, breathing becomes rapid and irregular, and every 30 seconds your eyes dart around inside your closed eyelids. |
| What happens in stage 4? | Brain emits large slow delta waves and are deep asleep. Last 30 min |
| What happens in stage 3? | Stage 3 is transitional and you begin to fall into a deep sleep, you are also in REM sleep. |
| What can occur in stage 2 of sleep? | Sleep spindles bursts of rapid, rhythmic brain activity. Sleep talking can also occur. Also in REM sleep. |
| What can occur in stage 1 sleep? | hallucinations |
| What are hallucinations? | They are false sensory experiences such as seeing something in the absence of an external stimulus. |
| What are delta waves? | They are the large, slow brain waves associated with deep sleep? |
| What is sleep? | paradoxical, natural, reversible loss of consciousness--as disinct from unconsciousness resulting from a coma, general aesthesia or hibernation. |
| What are alpha waves? | the relatively slow brain waves of a relaxed, awake state. |
| What is REM sleep? | Rapid eye movement sleep, a recurring sleep stage during which vivid dreams occur. Also known as paradoxical sleep because the msucles are relaxed (except for twitches) but other body systems are still active. |
| What is the biological clock? | It is when light strikes the retina causing suprachiasmatic nucleus to alter the production of biologically active substances. |
| What is circadian rhythm? | The biological block; regular bodily rhythms that occur on a 24-hour cycle |
| What is the pop-out phenomenon? | When some stimuli are so powerful that they are distinct and we are drawn to them. They demand our attention and this is not by choice. |
| What is change blindness? | When something changes around you and you do not notice because you are focused on another task. |
| What is inattentional blindness? | Failing to see visible objects when our attention is directed elsewhere |
| What is selective attention? | the focusing of conscious awareness on a particular situation |
| What is consciousness? | our awareness of ourselves and our enviornment |
