Concept
Any class (i.e., group, category) the members of which share one or more defining features.
In Pavlovian discrimination training, the stimulus that is regularly paired with a US. (Cf. CS-.)
In Pavlovian discrimination training, the stimulus that regularly appears in the absence of the US. (Cf. CS+.)
Differential outcomes effect
The finding that discrimination training proceeds more rapidly when different behaviors produce different reinforcers. Abbreviated DOE.
Discrimination
The tendency for a behavior to occur in the presence of certain stimuli, but not in their absence. (Cf. generalization.)
See differential outcomes effect.
Errorless discrimination training
A form of discrimination training in which the S- is introduced in very weak form and gradually strengthened. The usual result is that discrimination is achieved with few or no errors. Also called the Terrace procedure.
Excitatory gradient
In Spences theory of generalization and discrimination, a generalization gradient showing an increased tendency to respond to the S+ or CS+ and stimuli resembling them. (Cf. inhibitory gradient.)
Experimental neurosis
Any bizarre or neurotic-like behavior induced through an experimental procedure such as discrimination training.
Generalization
The tendency for a learned behavior to occur in the presence of stimuli that were not present during training. (Cf. discrimination.)
Generalization gradient
Any graphic representation of generalization data.
Inhibitory gradient
In Spences theory of generalization and discrimination, a gradient showing a decreased tendency to respond to the S- or CS- and stimuli resembling them. (Cf. excitatory gradient.)
Matching to sample
A discrimination training procedure in which the task is to select from two or more comparison stimuli the one that matches a sample. Abbreviated MTS.
Mismatching
A variation of matching to sample in which reinforcement is available for selecting the comparison stimulus that is different from the sample. Also called oddity matching.
Oddity matching
See mismatching.
Peak shift
The tendency following discrimination training for the peak of responding in a generalization gradient to shift away from the CS- or S-.
A stimulus in the presence of which a behavior will be reinforced. Also called SD, pronounced ess-dee. (Cf. S_.)
Semantic generalization
Generalization based on an abstract (as opposed to a physical) property of a stimulus.
Simultaneous discrimination training
A discrimination training procedure in which the S+ and S- are presented at the same time.
Stimulus control
The tendency for a behavior to occur in the presence of an S+ but not in the presence of an S-. (Cf. discrimination.)
Successive discrimination training
A discrimination training procedure in which the S+ and S- are presented one after the other in random sequence.
A stimulus in the presence of which a behavior will not be reinforced. Also called S?, pronounced ess-delta. (Cf. S+.)

Behavioral economics
See experimental economics.
Chain schedule
A complex reinforcement schedule that consists of a series of simple schedules, each of which is associated with a particular stimulus, with reinforcement delivered only on completion of the last schedule in the series. (Cf. tandem schedule.)
Concurrent schedule
A complex reinforcement schedule in which two or more simple schedules are available at the same time.
Continuous reinforcement
A reinforcement schedule in which a behavior is reinforced each time it occurs. Abbreviated CRF. (Cf. intermittent schedule.)
Cooperative schedule
A complex reinforcement schedule in which reinforcement is contingent on the behavior of two or more individuals.
See continuous reinforcement.
Discrimination hypothesis
The proposal that the PRE occurs because it is harder to discriminate between intermittent reinforcement and extinction than between continuous reinforcement and extinction.
Discrimination training
Any procedure for establishing a discrimination. Pavlovian discrimination training consists of presenting one stimulus (the CS+) with the US and presenting another stimulus (the CS-) without the US. Operant discrimination training normally consists of reinforcing a behavior when it occurs in the presence of one stimulus (the S+ or SD), but not when it occurs in the presence of another stimulus (the S- or S?). See errorless discrimination training; matching to sample; simultaneous discrimination training; successive discrimination training.
Discriminative stimulus
In operant discrimination training, any stimulus that signals either that a behavior will be re-inforced (an S+ or SD) or will not be re-inforced (an S- or S?).
Experimental economics
The use of reinforcement schedules, among other techniques, to study economic principles. Also called behavioral economics.
FD schedule
See fixed duration schedule.
FI schedule
See fixed interval schedule.
Fixed duration schedule
A reinforcement schedule in which reinforcement is contingent on the continuous performance of a behavior for a fixed period of time. -Abbreviated FD. (Cf. variable duration schedule.)
Fixed interval schedule
A reinforcement schedule in which a behavior is reinforced the first time it occurs following a specified interval since the last reinforcement. -Abbreviated FI. (Cf. variable interval schedule.)
Fixed ratio schedule
A reinforcement schedule in which every nth performance of a behavior is reinforced. Abbreviated
