A relatively permanent change in an organisms 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 (as in operant conditioning)
Classical Conditioning
A type of learning in which an organism comes to associate stimuli.

A neutral stimulus that signals an unconditioned stimulus begins to produce a response that anticipates and prepares for the unconditioned stimulus.

A view that psychology should be an objective science that studies behavior without reference to mental processes.
Unconditioned Response
In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus.
Unconditioned Stimulus
In classical conditioning, a stimulus that unconditionally--naturally and automatically--triggers a response.

Conditioned Response
In classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus.
Conditioned Stimulus
in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response.
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.

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 pause, of an extinguished conditioned response.
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses.
in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus.

Operant Conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher.
Respondent Behavior
behavior that occurs as an automatic response to some stimulus; Skinner's term for behavior learned through classical conditioning.
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
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.

An operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximation of the desired behavior.
In operant conditioning, any event that strengthens the behavior it follows.
Positive Reinforcement
increasing behaviors by presenting positive stimuli, such as food. Any stimulus that, when presented after a response, strengthens the response.
Negative Reinforcement
increasing the strength of a given response by removing or preventing a painful stimulus when the response occurs.
Primary Reinforcer
An innately reinforcing stimulus, such as one that satisfies a biological need.

Conditioned Reinforcer
A stimulus that gains its enforcing power through its association with a primary reinforcer; also known as 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
In operant conditioning, a reinforcement schedule that reinforces a response only after a specified number of responses.
Variable-Ratio Schedule
In operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses.

Fixed-Interval Schedule
In operant conditioning, a reinforcement schedule that reinforces after a specified time has elapsed.
Variable-Interval Schedule
In operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals.
An event that decreases the behavior that it follows.
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 its layout.

Latent Learning
learning that occurs but is not apparent until there is an incentive to demonstrate it
Intrinsic Motivation
A desire to perform a behavior for its own sake
Extrinsic Motivation
A desire to perform a behavior due to promised rewards or threats of punishment.
Observational Learning
Learning by observing others.
The process of observing and imitating a specific behavior.
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.
Prosocial Behavior
Positive, constructive, helpful behavior.

The opposite of antisocial behavior.
