The theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green & inhibited by red; others are stimulated by red & inhibited by green -As visual info leaves the receptor cells, we analyze it in terms of 3 sets of opponent colors. In the retina and in the thalamus (where impulses from the retina are relayed en route to the visual cortex), some neurons are turned "on" by red but turned "off" by green. Others are turned on by green but off by red

a genetically disposed deficiency in the natural brain systems for pleasure and well-being that leads people to crave whatever provides that missing pleasure or relieves negative feelings

Classical Conditioning*

a type of learning in which one learns to link two or more stimuli (a CS & the US it signals) and anticipate events (a neutral stimulus, paired with a previously meaningful stimulus, eventually takes on some meaning itself) -respondent behavior -pavlov & watson -ns,us,ur,cs,cr -acquisition -generalization -discrimination -extinction -spontaneous recovery

classical conditioning

a type of learning in which one learns to link two or more stimuli and anticipate events

many now think of the unconscious not as seething passions and repressive censoring but as cooler information processing that occurs without our awareness. To these researchers, the unconscious also involves -schemas -priming by stimuli to which we have not consciously attended -right-hemisphere activity that enables the split-brain patient's left hand to carry out an instruction the patient cannot verbalize -parallel processing of different aspects of vision and thinking -implicit memories that operate w/o conscious recall -emotions that activate before conscious analysis -self-concept & stereotypes that automatically and unconsciously influence how we process info

Eyesenck Personality Questionnaire

questionnaire by British psychologists that reduced our trait variations to 2 or 3 dimensions (extraversion-introversions, emotional stability -instability); results showed extraversion & emotionality factors emerged as basic personality dimensions-these factors are genetically influenced

Accidents (Phineas Gage)*

railroad worker (1848) who survived a severe brain injury to the frontal lobes that dramatically changed his personality and behavior (once soft spoken, friendly - became irritable, dishonest, profane) moral judgement became disconnected from behavior & emotions; case played a role in the development of the understanding of the localization of brain function

measures of variability*

range and standard deviation -shows how similar & diverse the scores are -averages derived from scores w/ low variability are more reliable than averages based on scores w/ high variability -how much the numbers in the set differ from one another

Results in alertness, arousal & appetite suppression. Use leads to anxiety, insomnia, heart problems, brain damage, movement disorders, confusion, paranoia, etc.

Caffeine

stimulant most popular drug. It reduces drowsiness and can enhance cognitive performance. At high doses it creates tremors & anxiety. Withdrawal symptoms can occur. -mild doses last 3-4 hours

primacy effect*

tendency to remember words at the beginning of a list especially well

inventory-type tests

tests used in psychology in which participants answer a standard series of questions

deja vu

that eerie sense that "I've experienced this before." Cues from the current situation may subconsciously trigger retrieval of an earlier experience. Theories: -current situation may be loaded w/ cues tht unconsciously retrieve an earlier, similar experience -a situation seems familiar when moderately similar to several events -dual processing error, if there's a slight neural hiccup & 1 track's signal is delayed, it may feel like a repeat of the earlier one, creating an illusion tht we are now reexperiencing something

Cerebellum*

the "little brain" at the rear of the brainstem; functions include processing sensory input and output COORDINATING MOVEMENT and BALANCE -enables 1 type of nonverbal learning & memory -helps judge time, modulate our emotions, discriminate sounds & textures -coordinates VOLUNTARY movement (w/ assistance from the pons) -if injured, would have trouble with coordination

pinna

the visible part of the ear, outer Part of the ear best able to aid us in the location of sounds

Circadian/evolutionary theory of sleep

theory of sleep says that sleep evolved to keep humans out of harm's way during the night

generalizable

valid in other contexts beyond the context in which the selection method was developed

social-cognitive perspective

views behavior as influenced by the interaction between people's traits (including their thinking) and their social context. -considered cognitive-behavioral approach -focus on how we & our environment interact (how do we interpret & respond to external events? How do our schemas, our memories, & our experiences influence our behavior patterns?) -first proposed by Albert Bandura -observe behavior in realistic situations Critiques: focuses too much on situation that fails to appreciate the person's inner traits (in many cases our personality traits predict behavior)

unit bias

when the portion size is larger, people will eat more

Healthy user bias

when the study population tends to be in better shape than the general population

tip of the tongue phenomenon

when we try to recall something we already know is available but isn't easily available for conscious awareness -demonstrates preconscious info may be available to the conscious mind but difficult to access
