the process of acquiring new information or behaviors through experience
2
New cards
associative learning
learning that certain events occur together; via conditioning or observation
3
New cards
stimulus
any event or situation that evokes a response.
4
New cards
respondent behavior
behavior that occurs as an automatic response to some stimulus.
5
New cards
operant behavior
behavior that operates on the environment to produce pleasant or unpleasant consequences
6
New cards
cognitive learning
the acquisition of mental information, whether by observing events, by watching others, or through language
7
New cards
classical conditioning
a type of learning in which we link two or more stimuli and anticipate events; how simple associations are formed
8
New cards
neutral stimulus (NS)
stimulus that doesn't naturally trigger a response ex. Bell
9
New cards
Unconditioned stimulus (US)
stimulus that triggers a reflexive response ex. Food
10
New cards
Unconditioned response (UR)
a natural (unlearned) reflexive behavior elicited by the US ex. salivation in dog
11
New cards
Conditioned stimulus (CS)
neutral stimulus that elicits a response after being repeatedly paired with the US ex. Bell
12
New cards
Conditioned response (CR)
the behavior that is caused by the CS (typically the same as the UR, but now it is paired with the CS) ex. Salivation in dog
13
New cards
acquisition
period where organism connects neutral stimulus and unconditioned stimulus
14
New cards
extinciton
decrease of CR when CS occurs but US is no longer presented; ex. ring bell over and over again but no longer present food
15
New cards
spontaneous recovery
return of previously extinguished CR spontaneously after a rest period; Take a break from ringing the bell, then ring after several hours; dogs may start drooling again
16
New cards
generalization
responding similar to stimuli that are similar to the CS
17
New cards
discrimination
being able to distinguish between the CS and other, irrelevant stimuli
18
New cards
operant conditioning
a type of learning in which a behavior becomes more probable if followed by a reinforcer or less probable if followed by a punisher.
19
New cards
law of effect
Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely.
20
New cards
reinforcement
anything that makes a behavior more likely (strengthens)
21
New cards
reinforcer
a positive or negative stimulus used to create reinforcement
22
New cards
shaping
an operant conditioning procedure in which reinforcers guide actions closer and closer toward a desired behavior
23
New cards
positive reinforcement
add something to the environment to make behavior more likely
24
New cards
negative reinforcement
remove something from the environment to make behavior more likely; not the same as punishment as it removes a punishing event
25
New cards
primary reinforcer
unlearned reinforcers: naturally desirable (ex. food to remove hunger)
26
New cards
reinforcement schedule
a pattern that defines how often a desired response will be reinforced
27
New cards
continuous reinforcement
reinforcer provided every time behavior occurs; learn behavior faster, but stop quickly after reinforcement stops
28
New cards
partial (intermittent) reinforcement
don't always provide reinforcement for behavior; learn behavior slower, but behavior continues longer after reinforcement stops
29
New cards
fixed-ratio schedule
(type of intermittent reinforcement) reinforce after every X number of behaviors; e.g. free coffee after 10 cups
30
New cards
variable-ratio schedule
reinforce after unpredictable number of responses; e.g. email spammers; type of intermittent reinforcement
31
New cards
fixed-interval schedule
reinforce first behavior after a certain amount of time has passed; e.g. checking cookies to see if done; type of intermittent reinforcement
32
New cards
variable-interval schedules
reinforce first behavior after unpredictable amount of time; e.g. see a message from a crush every once in a while when you check messaging app; type of intermittent reinforcement
33
New cards
punishment
an event that decreases the behavior it follows; positive adds and undesirable stimulus to decrease behavior and negative takes something away to decrease behavior
34
New cards
latent learning
may cognitively learn a new environment or information without reinforcement or effort
35
New cards
intrinsic motivation
a desire to perform behavior well for its own sake
36
New cards
extrinsic motivation
the desire to perform a behavior to receive promised rewards or avoid threatened punishment
37
New cards
observational learning
learning that occurs from watching others and then imitating or modeling their actions
38
New cards
modeling
the process of observing and imitating a specific behavior
39
New cards
memory
the nervous system's capacity to retain and retrieve skills and knowledge (the persistence of learning over time); often incomplete, biased, and distorted
40
New cards
information-processing model
compares human memory to computer's operation; involves encoding, storage, and retrieval
41
New cards
encoding
input of information into the memory system; Labeling and coding sensory information from the environment
42
New cards
storage
retaining information over time; The brain itself is changed by what is experienced, recording it as a memorable event
43
New cards
retrieval
accessing or retrieving information from memory storage
44
New cards
sensory memory
when a light, a sound, an odor, a taste, or a tactile impression leaves a vanishing trace on the nervous system (immediate, very brief)
45
New cards
iconic memory
visual sensory memory
46
New cards
echoic memory
auditory sensory memory
47
New cards
short-term memory
activated memory that holds a few items briefly (such as digits of a phone number while calling) before the information is stored or forgotten; aka working memory
48
New cards
long-term memory
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.
49
New cards
working memory
a newer understanding of short-term memory that adds conscious, active processing of incoming sensory information, and of information retrieved from long-term memory; info remains in working memory for 20-30 seconds unless you do something to retain it
50
New cards
implicit memory
nondeclarative memory; memory that occurs without conscious awareness, often unable to put into words; includes memory acquired through classical conditioning and procedural memory (motor skills/habits)
51
New cards
explicit memory
declarative memory; facts and events we can consciously know and declare; two types
52
New cards
episodic memory
information about past experiences, including the time and place an event occurred; type of explicit/declarative memory
53
New cards
semantic memory
knowledge of facts, regardless of personal experience; type of explicit/declarative memory
54
New cards
chunking
organizing information into familiar, meaningful units
55
New cards
mnemonics
associating new information with mental images (or other vivid and memorable tools—like songs or rhymes)
56
New cards
spacing effect
distributed practice produces better long-term recall
57
New cards
testing effect
repeated self-testing (e.g. taking practice tests and quizzes)
58
New cards
rehearsal
two types: maintenance is simply repeating an item of information over and over; elaborative is encoding in a more meaningful way
59
New cards
hippocampus
involved in temporarily storing new memories of facts and events
60
New cards
amygdala
stores emotionally-charged memories; e.g. traumatic events or world changing events
61
New cards
memory consolidation
memories are moved to other parts of the brain for long-term storage
62
New cards
long-term potentiation (LTP)
increase in neuron's firing potential after repeated activation; The more one neuron excites another (by releasing neurotransmitters), the easier it is to activate the postsynaptic neuron in the future; lasting strengthening changes
63
New cards
recall
memory demonstrated by retrieving information learned earlier, e.g. remembering the name of a new acquaintance
64
New cards
recognition
memory demonstrated by identifying items that have been previously learned, e.g. asking whether "Sarah" is the name of your new acquaintance
65
New cards
relearning
memory demonstrated by being able to learn something faster the second time it is presented
66
New cards
retrieval cue
Associations to an encoded memory, often stored along with the memory; activating that web of associations makes it easier to recall information stored in long-term memory
67
New cards
priming
usually unconscious activation of associations to particular memories; E.g. Snow and slippery roads
68
New cards
mood-congruent memory
easier to recall memories that are consistent with current mood
69
New cards
serial position effect
our tendency to recall best the last and first items in a list
70
New cards
proactive interference
when older memory makes it more difficult to remember new information
71
New cards
retroactive interference
new learning disrupts your memory of older information
