operant conditioning
a type of learning which behavior is strengthened if followed by a reinforcement or diminished if followed by a punishment
classical conditioning
a type of learning in which an organism comes to associate stimuli. a neutral stimulus that signals an unconditioned stimulus (UCS) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlonian conditioning
unconditioned response
In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus such as salivation when food is in the mouth
conditioned response
In classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus
unconditioned stimulus
In classical conditioning, 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
acquisition
the initial stage of learning; the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response
extinction
the diminishing of a conditioned response; in classical conditioning this occurs when an unconditioned stimulus does not followed a conditioned stimulus
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
discrimination
In classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
reinforcement
anything that strengthens the behavior it follows
punishment
an event that decreases the behavior that it follows
primary reinforcer
an innately reinforcing stimulus, such as one that satisfies a biological need
intrinsic motivation
a desire to perform a behavior effectively for its own sake
extrinsic motivation
a desire to perform a behavior due to promised rewards or threat of punishment
variable interval
in operant conditioning, a schedule reinforcement that reinforces a response at unpredictable time intervals
variable ratio
In operant conditioning, a schedule reinforcement that reinforces a response after an unpredictable number of responses
fixed interval
In operant conditioning, a schedule reinforcement that reinforces a response only after a specified time has elapsed
fixed ratio
In operant conditioing, a schedule reinforcement that reinforces a response only after a specified number of responses
latent learning
learning that occurs but is not apparent until there is an incentive to demonstrate it
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
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
Behaviorism
a 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).
Modeling
the process of observing and imitating a specific behavior
Operant behavior
behavior that operates on the environment, producing consequences
Overjustification effect
the effect of promising a reward for doing what one already likes to do.

The person may now see the reward, rather than intrinsic interest, as the motivation for performing the task

Respondent behavior
behavior that occurs as an automatic response to some stimulus; Skinner's term for behavior learned through classical conditioning
Shaping
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of a desired goal
