Document Summary
Failure to see visible objects because our attention is occupied elsewhere is called inattentional blindness. We register and react to stimuli outside of our awareness by means of unconscious processing. When we devote deliberate attention to stimuli, we use conscious processing. Our body temperature tends to rise and fill in sync with a biological clock, which is referred to as circadian rhythms. During stage nrem-1 sleep, a person is most likely to experience: sleep spindles, hallucinations, night terrors or nightmares, rapid eye movements. The brain emits large, slow delta waves during nrem-3 sleep. With narcolepsy, the person periodically falls directly into rem sleep, with no warning; with sleep apnea, the person repeatedly awakens during the night. In interpreting dreams, freud was most interested in their: information-processing function, physiological functions, manifest content, or story line, latent content, or hidden meaning. The neural activation theory suggests that dreams are the brain"s attempt to make sense of random neural activity.
