Unit 4: Learning Flashcards

1
Q

Albert Bandura

A

Observational learning /Social learning

learn social behaviors mostly thru observation & cognitive processing of info, rather than thru direct experience

learning to anticipate the consequences of an action by observing its consequences for someone else (vicarious conditioning(reinforcement/punishment aka observational learning)

Famous bobo doll experiment that revealed children modeling behavior in adults (specifically aggression toward the doll)

Q

Bobo Doll Experiment by Albert Bandura

A

revealed children modeling behavior in adults (specifically aggression toward the doll)

children are able to learn social behavior ex: aggression thru observation learning, ( watching the behavior of another person - adults)

children viewed a film of an adult violently hitting an inflatable “Bobo” doll and were allowed to play with the doll. The children then showed aggression towards the doll

Q

Latent Learning

A

learning that occurs but is not apparent until there is an incentive/motivation to demonstrate it

(more to learning then associating a response w/ a consequence; there is cognition)

Q

Acquisition

A

classical conditioning ->
When a behavior, such as a conditioned response, has been learned.

(initital stage) one links a neural stimulus w/ an unconditioned stimulus so NS triggers conditioned response

Learning to pair CS to UCS

Q

Extinction

A

classical conditioning ->

Diminishing of a conditioned response; occurs when an UCS does not follow a CS

The cease of a learned response, usually resulting from an end to conditioning

Q

Generalization

A

(CC) Once response = conditioned, tendency for similar stimulus to CS to elicit a similar response

Respond the same to stimulus similar to conditioned stimulus

ex: if u hear a bell u will jump so then if u hear a ringing noise u will also jump

Q

Higher-order conditioning (cc) / second-order conditioning

A

procedure, conditioned stimulus in one conditioning experience = paired w/ a new neural stimulus, creating a 2nd (often weaker) conditioned stimulus,

ex: animal learns a bell predicts food, might learn a light predicts the bell, & begin responding to light alone

only responding to one thing

25
Unconditioned Stimulus
in classical conditioning something that unconditionally; naturally & automatically triggers a response A stimulus capable of reflexively evoking a response
26
Unconditioned Response
(CC) the unlearned & naturally occurring response to unconditioned stimulus (ex; dog salivating to food) A reflexive response produced by an unconditioned stimulus
27
Neutral stimulus
A stimulus that does not produce a reflexive response, evokes no response before conditioning
28
Conditioned stimulus
A neutral stimulus that produces a conditioned response because it has been repeatedly paired with an unconditioned stimulus
29
Conditioned Response
a learned response to a previously neutral stimulus A learned response produced by a conditioned stimulus paired w/ UCS
30
Classical Conditioning / Associative learning
We link 2 /2+ stimuli, 1st stimulus (a bell) comes to elicit behavior (drooling) in anticipation of the second stimulus (food) A method of learning that creates new associations between neutral stimuli and reflex-causing stimuli (UCS)
31
Observational / Social learning
A form of learning that occurs by watching the behaviors of others learn w/o direct experience by watching/imitating others (modeling)
32
Mirror Neurons
frontal lobe neurons, believed to fire when we perform certain actions / observe others performing certain actions brain's mirroring of another's action may enable imitation & empathy observational learning
33
Modeling
the process of observing & imitating a specific behavior
34
Prosocial Behavior
positive, constructive, helpful behavior opposite of antisocial behavior
35
Antisocial Behavior
negative behavior
36
Operant Conditioning
Behavior becomes more likely to recur if followed by a reinforcer / less likely to recur if followed by punishment method of learning that alters the frequency of a behavior by manipulating its consequences through reinforcement or punishment
37
Respondent Behavior
behavior that occurs as an automatic response to some stimulus
38
Law Of Effect
principle: behaviors followed by favorable consequences = more likely but behaviors followed by unfavorable consequences = less likely
39
Operant chamber
a chamber aka Skinner box, containing a bar / key that an animal can manipulate to obtain a food / water reinforcer, w/ attached devices to record the animal's rate of bar pressing or key pecking
40
Shaping
Procedure: reinforcers guide behavior toward closer & closer approximations of desired behavior
41
Reinforcement
any event that strengthens the behavior it follows
42
Punishment
an event that tends to decrease the behavior that it follows
43
Discriminitive Stimulus
A stimulus that elicits a response after association w/ reinforcement (contrasts related stimuli not associated w/ reinforcement) a stimulus, increases the probability of a response because of a previous history of differential reinforcement in the presence of that stimulus For ex: if a pigeon’s key pecks are reinforced when the key is illuminated red but not when the key is green, the red stimulus will come to serve as an SD and the pigeon will learn to peck only when the key is red. signals that a response will be reinforced
44
Primary Reinforcer
an innately reinforcing stimulus ex: one that satisfies biological need (water, food, shelter, self-esteem)
45
Conditioned / Secondary Reinforcer
stimulus, gains reinforcing power thru association w/ primary reinforcer (ex: money, toys)
46
Positive Reinforcement
Any pleasant stimulus rewarded after a desired behavior (ex: pet a dog that comes when u call it) Increasing behavior by presenting positive reinforcers (anystimulus that when presented after a response, STRENGTHENS the response)
47
Negative Reinforcement
increasing a behavior by stopping/reducing an unpleasant stimulus. (ex: taking painkillers to end pain) Any unpleasant stimulus that when removed after a response, STRENGTHENS the response(not punishment)
48
Positive Punishment
a stimulus u dony like (aversive stimulus, ex: a slap)
49
Negative Punishment
taking away rewarding stimulus (ex: taking away ur phone)
50
Reinforcement Schedule
a pattern that defines how often a desired response will be reinforced
51
Continuous reinforcement schedule (OC)
Reinforcing the desired response every time it occurs
52
Partial (intermittent) reinforcement schedule (OC)
Reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than continuous reinforcement
53
Fixed ratio (OC)
KNOW exactly after SPECIFIC NUMBER of RESPONSES = reward/reinforcement (consistent)
54
Fixed interval (OC)
KNOW reinforcement/reward happens after a SPECIFIC TIME elapses (consistent)
55
Variable ratio (OC)
DONT know when reinforcement/reward is going to come after UNPREDICTABLE NUMBER of RESPONSES
56
Variable interval (OC)
DONT know when reinforcement/reward is going to happen after an UNPREDICTABLE NUMBER of TIME
57
Biofeedback
The electronic monitoring of autonomic functions (like heart rate, blood pressure, or stress responses) for the purpose of bringing those functions under partially voluntary control
58
Systematic desensitization
A behavior modification technique that attempts to treat phobias through planned exposure to fearful stimuli
59
Aversion therapy
A process of behavior modification that works by associating an undesirable habitual behavior with an aversive stimulus
60
Higher-order conditioning (cc) / second-order conditioning
procedure, conditioned stimulus in one conditioning experience = paired w/ a new neural stimulus, creating a 2nd (often weaker) conditioned stimulus, ex: animal learns a bell predicts food, might learn a light predicts the bell, & begin responding to light alone
