Hallucination

People perceive objects or events that have no external reality

Conductive hearing loss

Poor transfer of sounds from the eardrum to the inner ear.

Drug-dependency insomnia

Prescription sedatives and sleeping aids can sometimes prove to be ineffective due to their impact on certain stages of sleep, which can result in even further lack of sleep

plays a key role in transferring information from short-term memory to long-term memory

Drug tolerance

progressive decrease in a person's responsiveness to a drug

proposition that color vision is based on coding things as red or green, yellow or blue, or black or white

Perceptual expectancy

refers to past experience, motives, context, or suggestions that prepare you to perceive in a certain way

state of consciousness characterized by focused attention, reduce peripheral awareness, and heightened suggestibility

suspected as one cause of sudden infant death syndrome (SIDS), or "Crib death"

Tip of the tongue state

the feeling that a memory is available but not quite retrievable

Trichromatic theory

theory of color vision based on three cone types: red, green, and blue

theory proposes that dreams are how brains process the random electrical dischargers of REM sleep

thinking about thinking
