learning
answer
a relatively permanent change in behavior due to experience
question
behaviorism
answer
an approach to psychology that emphasizes the study of observable behavior and the role of the environment and prior experience as determinants of behavior
question
conditioning
answer
a basic kind of learning that involves associations among environmental stimuli and an organism's behavior
question
Pavlov
answer
studied salivation in dogs as part of a research program on digestion
question
unconditioned stimulus (US)
answer
US, the classical-conditioning term for a stimulus that already elicits a certain response without additional learning; original salivary reflex
question
unconditioned response (UR)
answer
UR, the classical conditioning term for a response elicited by an unconditioned stimulus, salivation
question
conditioned stimulus (CS)
answer
CS, the classical conditioning term for an initially neutral stimulus that comes to elicit a conditioned response after being associated with an unconditioned stimulus; food dish
question
conditioned response (CR)
answer
CR, the classical conditioning term for a response that is elicited by a conditioned stimulus; it occurs after the conditioned stimulus is associated with an unconditioned stimulus; dog response
question
classical conditioning
answer
the process by which a previously neutral stimulus becomes associated with a stimulus that already elicits a response and, in turn, acquires the capacity to elicit a similar or related response; PAVLOVIAN, or RESPONDENT conditioning
question
extinction (classical)
answer
the weakening and eventual disappearance of a learned response; in classical conditioning, it occurs when the conditioned stimulus is no longer paired with the unconditioned stimulus
question
spontaneous recovery
answer
the reappearance of a learned response after its apparent extinction
question
higher-order conditioning
answer
in classical condition, a procedure in which a neutral stimulus becomes a conditioned stimulus through association with an already established conditioned stimulus- chain
question
stimulus generalization
answer
SIMILAR STIMULI, SIMILAR REACTION; after conditioning, the tendency to respond to a stimulus that resembles one involved in the original conditioning; it occurs when a stimulus that resembles the CS elicits the CR
question
stimulus discrimination
answer
the tendency to respond differently to two or more similar stimuli; in classical conditioning, it occurs when a stimulus similar to the CS fails to evoke the CR; different responses are made to stimuli that resemble the conditioned stimulus, piano notes
question
precede
answer
for classical conditioning to be most effective, the stimulus to be conditioned should be ___ the unconditioned stimulus
question
signal
answer
the conditioned stimulus becomes a ___ for the unconditioned stimulus
question
predict
answer
to become a conditioned stimulus, the neutral stimulus must signal, or ___, the unconditioned stimulus
question
John B. Watson
answer
founded American behaviorism and enthusiastically promoted Pavlov's ideas.
question
learning to like
answer
in classical conditioning terms, the things we enjoy are the unconditioned stimulus for the internal response of pleasure
question
learning to fear
answer
humans are prepared to acquire some kinds of fear
question
phobia
answer
when fear becomes irrational and interferes with normal activities
question
Little Albert
answer
rat and hammer; boy was scared of loud hammer noises, but the rat comforted him
question
counterconditioning
answer
in classical conditioning, the process of pairing a conditioned stimulus with a stimulus that elicits a response that is incompatible with an unwanted conditioned response; Peter liked cookies and milk, learned to like rabbits
question
systematic desensitization
answer
a type of counterconditioning that associates a pleasant relaxed state with gradually increasing anxiety-triggering stimuli
question
amygdala
answer
part of the brain that plays a central role in the conditioning of fear, in part because of a receptor for the neurotransmitter glutamate
question
operant conditioning
answer
INSTRUMENTAL CONDITIONING, the process by which a response becomes more likely to occur or less so, depending on its consequences
question
tantrum
answer
behavior becomes more or less likely depending on its consequences
question
how operant conditioning works
answer
organism's response operates the environment, these effects influence whether the response will occur again
question
central feature in operant conditioning
answer
is an association between a stimulus and a response
question
classical vs. operant conditioning
answer
classical response- reflexive, automatic operant response- complex, not reflextive
question
Edward Thorndike
answer
cat box
question
B. F. Skinner
answer
argued that to understand behavior, we should focus on the external causes of an action and the action's consequences; to explain behavior, we should look outside the animal/person not inside
question
consequences of behavior
answer
a response can be influenced by two types of consequences
question
1. Reinforcement strengthens the response or makes it more likely to recur
answer
reinforcers=rewards
question
2. Punishment weakens the response or makes it less likely to recur
answer
punisher- aversive/unpleasant stimulus
question
reinforcement
answer
the process by which a stimulus or event strengthens or increases the probability of the response that it follows
question
punishment
answer
the process by which a stimulus or event weakens or reduces the probability of the response that it follows
question
primary reinforcer
answer
a stimulus that is inherently reinforcing; typically satisfying a physiological need; an example is food
question
primary punisher
answer
a stimulus that is inherently punishing; an example is electric shock
question
secondary reinforcer
answer
a stimulus that has acquired reinforcing properties through association with other reinforcers; money
question
secondary punisher
answer
a stimulus that has acquired punishing properties through association with other punishers; criticism
question
positive reinforcement
answer
a reinforcement procedure in which a response is followed by the presentation of, or increase in intensity of, a reinforcing stimulus; as a result, the response becomes stronger or more likely to occur; good grade after studying
question
negative reinforcement
answer
a reinforcement procedure in which a response is followed by the removal, delay, or decrease in intensity of an unpleasant stimulus; as a result, the response becomes stronger or more likely to occur; studying to avoid nagging
question
punishment decreases the likelihood of a response
answer
reinforcement increases the likelihood of a response
question
Skinner box
answer
device that delivers a reinforcement, food, when an animal makes the appropriate response
question
extinction (operant)
answer
the weakening and eventual disappearance of a learned response; in operant conditioning, it occurs when a response is no longer followed by a reinforcer
question
spontaneous recovery
answer
vending machine; alcoholic/drug abuse relapse
question
stimulus generalization (operant)
answer
in operant conditioning, the tendency for a response that has been reinforced in the presence of one stimulus to occur in the presence of other similar stimulus
question
stimulus discrimination (operant)
answer
in OC, the tendency of a response to occur in the presence of one stimulus but not in the presence of other similar stimuli that differ from it on some dimension
question
discriminative stimulus
answer
a stimulus that signals when a particular response is likely to be followed by a certain type of consequence
question
continuous stimulus
answer
a reinforcement in which a particular response is always reinforced
question
intermittent (partial) schedule of reinforcement
answer
a reinforcement schedule in which a particular response is sometimes but not always reinforced
question
shaping
answer
an operant-conditioning procedure in which successive approximations of a desired response are reinforced; pigeons
question
successive approximations
answer
in the operant-conditioning procedure of shaping, behaviors that are ordered in terms of increasing similarity or closeness to the desired response
question
instinctive drift
answer
during operant learning, the tendency for an organism to revert to instinctive behavior; Breland's and pig
question
determinist view
answer
our actions are determined by our environments and our genetic heritage
question
behavior modification
answer
the application of OC techniques to teach new responses or to reduce or eliminate maladaptive or problematic behavior; also called applied behavior analysis
question
consistency
answer
what matters most to a punishment is not severity, but ___
question
when punishment fails
answer
1. people often administer punishment inappropriately or mindlessly 2. the recipient of harsh/frequent punishment often responds with anxiety, fear, or rage 3. the effectiveness of punishment is often temporary, depending heavily on the presence of the punishing person or circumstances 4. most misbehavior is hard to punish immediately 5. punishment conveys little information 6. an action intended to punish may instead by reinforcing because it brings attention
question
when punishment must be applied
answer
1. should not involve physical abuse 2. be consistent 3. accompanied by info about the kind of behavior that is appropriate 4. be followed by reinforcement of desirable behavior
question
rewards do not always work as expected
answer
high self-esteem doesn't improve academic performance
question
extrinsic reinforcers
answer

intrinsic reinforcers
answer
reinforcers that are inherently related to the activity being reinforced; enjoyment of task/satisfaction
question
behavioral ABCs
answer
antecedents (events preceding behavior), behaviors, and consequences
question
latent learning
answer
a form of learning that is not immediately expressed in an overt response; it occurs without obvious reinforcement; rat in maze with right/left cues
question
social-cognitive theories
answer
theories that emphasize how behavior is learned and maintained through observation and imitation of others, positive consequences, and cognitive processes such as plans, expectations, and beliefs
question
observational learning
answer
a process in which an individual learns new responses by observing the behavior of another (a model) rather than through direct experience; sometimes called vicarious conditioning
question
model
answer
another person behaving in certain ways and experiencing the consequences
question
aggressive
answer
some people become more ___ after exposure to violent images in the media
