Myers Exploring Psychology Chapter 7

discrimination

in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus

conditioned response

in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS).

unconditioned response (UCR)

in classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (UCS), such as salivation when food is in the mouth

fixed-interval schedule

in operant conditioning, a schedule of reinforcement that reinforces a response after an unpredictable number of responses

variable-ratio schedule

in operant conditioning, a schedule of reinforcement that reinforces a response after an unpredictable number of responses

variable-interval schedule

in operant conditioning, a schedule of reinforcement that reinforces a response at unpredictable time intervals

fixed-ratio schedule

in operant conditioning, a schedule of reinforcement that reinforces a response only after a specified number of responses

reinforcer

in operant conditioning, any event that strengthens the behavior it follows

observational learning

learning by observing others

associative learning

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

latent learning

learning that occurs but is not apparent until there is an incentive to demonstrate it. Latent learning is associated with research by EC Tolman (Myers Psychology 8e p. 334)

prosocial behavior

positive, constructive, helpful behavior. The opposite of antisocial behavior

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

continuous reinforcement

reinforcing the desired response every time it occurs

extinction

the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced.

spontaneous recovery

the reappearance, after a rest period, of an extinguished conditioned response

generalization

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

behaviorism

the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2).

operant chamber

a chamber also known as a Skinner box, containing a bar or key that an animal can manipulate to obtain a food or water reinforcer, with attached devices to record the animal's rate of bar pressing or key pecking. Used in operant conditioning research. (Myers Psychology 8e p. 327)

extrinsic motivation

a desire to perform a behavior due to promised rewards or threats of punishment

intrinsic motivation

a desire to perform a behavior for its own sake and to be effective

cognitive map

a mental representation of the layout of one's environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it.

learning

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

classical conditioning

a type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlovian or respondent conditioning.

operant conditioning

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

punishment

an event that decreases the behavior that it follows

primary reinforcer

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

shaping

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

respondent behavior

behavior that occurs as an automatic response to some stimulus

operant behavior

behavior that operates on the environment, producing consequences

conditioned reinforcer

A stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as secondary reinforcer.

acquisition

The initial stage in classical conditioning; the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response. In operant conditioning, the strengthening of a reinforced response.

mirror neurons

frontal lobe neurons that fire when performing certain actions or when observing another doing so. The brain's mirroring of another's action may enable imitation, language learning, and empathy.

unconditioned stimulus (UCS)

in classical condidtioning, a stimulus that unconditionally naturally and automatically triggers a response

conditioned stimulus

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

modeling

The process of observing and imitating a specific behavior.

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
