Chapter 7

learning

a relatively permanent change in an organism's behavior due to experience

associative learning

learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences

classical conditioning

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

behaviorism

the view that psychology should be an objective science that studies behavior without reference to mental processes. Most research psychologists today agree with first claim, but not second

unconditioned response

unlearned, naturally occurring responses to unconditioned stimulus

unconditioned stimulus

stimulus that unconditionally triggers a response

conditioned response

learned response to a previously neutral stimulus

conditioned stimulus

originally, irrelevant stimulus, that after association with an unconditioned stimulus, comes to trigger a conditioned response

acquisition

initial stage in cc when one links a neutral stimulus to an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response

high-order conditioning

procedure in which conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second conditioned stimulus

extinction

diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus does not follow a conditioned stimulus

spontaneous recovery

reappearance, after a pause, of an extinguished conditioned response

generalization

tendency once a response has been conditioned for stimuli similar to the conditioned stimulus to elicit similar responses

discrimination

cc, learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus

respondent behavior

behavior that occurs as an automatic response to some stimulus

operant conditioning

type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher

operant behavior

behavior that operates on the environment, producing consequences

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

operant chamber

(skinner box) a chamber containing a bar or key that an animal can manipulate to obtain a food, or water reinforcer; attached devices record the animal's rate of bar pressing or key pecking

shaping

operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of desired behavior

reinforcer

operant conditioning, any event that strengthens the behavior it follows

positive reinforcement

presenting positive stimuli

negative reinforcement

increasing behavior by stopping or removing negative stimuli

primary reinforcer

innately reinforcing stimulus, such as one that satisfies a biological need

conditioned reinforcer

stimulus that gains its reinforcing power through its association with a primary reinforcer; secondary reinforcer

continuous reinforcement

reinforcing the desired response every time it occurs

partial (intermittent reinforcement)

reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement

fixed-ratio schedule

reinforcement schedule that reinforces a response only after a specified number of responses

variable-ratio schedule

reinforcement schedule that reinforces a response after an unpredictable number of responses

fixed-interval schedule

reinforcement schedule that reinforces a response only after a specified time has elapsed

variable-interval schedule

reinforcement schedule that reinforces a response at unpredictable time intervals

punishment

an even that decreases the behavior that it follows

positive punishment

administer an aversive stimulus (parking ticket)

negative punishment

withdraw a desirable stimulus (revoked driver's license)

cognitive map

mental representation of layout of one's environment.

latent learning

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

intrinsic motivation

desire to perform a behavior effectively for its own sake

extrinsic motivation

desire to perform a behavior to receive promised rewards or avoid threatened punishment

observational learning

learning by observing others

modeling

process of observing and imitating a specific behavior

prosocial behavior

positive, constructive, helpful behavior, opposite of antisocial behavior
