25
declarative memory
sometimes called fact memory, it is memory for explicit info
26
dissonance theory
the tendency to change thoughts or behavior in response to perceived inconsistencies
27
echoic memory
auditory memory
28
eidetic memory
memory for images
29
elaborative rehearsal
the process of organizing info and associating it with what you already know to get info into long-term memory
30
Emmert's law
a law describing the relationship between size constancy and apparent distance--the farther away the object appears to be, the more the scaling device in the brain will compensate for its retinal size by enlarging our perception of the object
31
episodic memory
a type of declarative memory, episodic memory refers to memories for particular events, or episodes, from personal experience
32
extinction
in operant conditioning, it is when a conditioned stimulus is repeatedly not reinforced and as a result, the conditioned response is no longer produced as consistently
33
extrinsic motivation
behavior that is motivated by some external reward
34
fixed action pattern
a behavior that is relatively stereotyped and appears to be species-specific
35
fluid intelligence
proposed by raymond cattell, it is a type of intelligence that has the ability to quickly grasp relationships in novel situations and make correct deductions from them
36
Generation-recognition model
model that proposes that recall tasks tap the same basic process of accessing information in memory as recognition tasks, but also require an additional processing step
37
ground
a concept in visual perception that refers to the background against which the figures appear
38
iconic memory
visual memory
39
induced motion
an illusion of movement occurring when everything around the spot of light is moved
40
intrinsic motivation
motivation by some reward that is inherent to the task
41
isomorphism
a theory that suggests there is a one-to-one correspondence between the object in the perceptual field and the pattern of stimulation in the brain
42
language acquisition device (LAD)
proposed by noam chomsky, this is innate, biologically based mechanism that helps us understand rule structures in language
43
law of closure
from gestalt psychology, it is the tendency for people to perceive complete figures even when the actual figures are not complete
44
law of effect
proposed by E.L. Thorndike, the law holds that if a response is followed by an annoying consequence, the animal will be less likely to emit the same response in the future
45
law of good continuation
from gestalt continuation psychology, it is the tendency for elements appearing to follow in the same direction (such as a straight line or a simple curve) to be grouped together
46
law of proximity
from gestalt psychology, it is the tendency for similar objects to be grouped together
47
levels of processing theory (depth of processing theory)
proposed by craik and lockart, the theory suggests that there is only one memory system, and that items entering the memory are analyzed in one of three stages: physical (visual), acoustical (sound), or semantic (meaning)
48
lightness constancy
refers to the fact that, despite changes in the amount of light falling on an object (illumination), the apparent lightness of the object remains unchanged
49
linear perspective
a cue for depth perception that refers to the perception of parallel lines converging in the distance
50
long-term memory
the memory system that holds a permanent sore of information
51
maintenance rehearsal
the process of rehearsing info so that items remain in short-term memory for a longer duration than usual
52
metacognition
the ability to think about and monitor cognition
53
metamemory
the ability to think about and monitor memory
54
motion parallax
a cue for depth perception that occurs during movement when objects that are closer appear to move
55
negative reinforcement
the probability that the desired response will be performed is increased by removing something undesirable whenever the desired response is made
56
operant conditioning
instrumental conditioning, reward learning, is based on learning the relationship between one's actions and their consequences
57
opponent process theory of color vision
ewald hering's theory that there are four primary colors in additive color mixing (red, blue, green and yellow) and that the primary colors are arranged in opposing pairs
58
paivio's dual code hypothesis
according to this theory, info can be stored or encoded in two ways: visually and verbally. abstract info tends to be encoded verbally, whereas concrete info tends to be encoded visually and verbally
59
positive reinforcement
increasing the probability that a desired response will be performed by reinforcing that response when it does occur
60
procedural memory
memory for how things are done
61
relative size
a cue for depth perception that occurs when as an object gets farther away and its image on the retina gets smaller. people can tell how far away something is relative to another object by comparing the size of the images on the retina with what is known about actual sizes
62
semantic memory
a type of declarative memory, semantic memory has to do with remembering general knowledge, especially the meanings of words and concepts
63
sensory memory
part of the stage theory of memory that contains the fleeting impressions of sensory stimuli
64
short-term memory
a memory system that has a limited capacity and a relatively short duration
65
size constancy
when an object appears to retain its size despite the fact that its image on the retina has changed its size
66
theory of multiple intelligences
howard gardner's theory that there are seven intelligence factors: linguistic ability, logical-mathematical, spatial ability, musical ability, bodily ability, interpersonal ability, interpersonal ability
67
top-down processing
from object recognition theory, it refers to when people recognize objects by using conceptual processes such as memories and expectations about the whole object
68
triarchic theory
robert sternberg's theory of intelligence that suggests that there are three aspects to intelligence: componential (performance on tests), experiential (creativity), and contextual (street smarts)
69
unconditioned response
in classical conditioning, it is a response that occurs w/o any behavioral conditioning--reflex
70
unconditioned stimulus
in classical conditioning, it is a stimulus that elicits an unconditioned response, without any behavioral conditioning
