Term
Rate
Definition
Number of responses per unit of time.
Term
Duration
Definition
A measure of the total extent of time in which a behavior occurs.
Term
Latency
Definition
Elapsed time from the onset of a stimulus to the initiation of a response.
Term
Interresponse Time
Definition
The elapsed time between two successive responses.
Term
Dimensions of Applied Behavior Analysis (Naming)
Definition
Behavioral, Applied, Technological, Conceptually Systematic, Analytic, Generality, Effective.
Term
Behavioral
Definition
Entails precise measurement of the actual behavior in need of improvement and documents that it was the subject's behavior that changed.
Term
Applied
Definition
Investigates socially significant behaviors with immediate importance to the subject.
Term
Technological
Definition
The written description of procedures used in the study is sufficiently complete and detailed to enable others to replicate it.
Term
Conceptually Systematic
Definition
Behavior change interventions are derived from basic principles of behavior.
Term
Analytic
Definition
Demonstrates experimental control over the occurrence and nonoccurence of the behavior--that is, if a functional relation is demonstrated.
Term
Generality
Definition
Produces behavior change that lasts over time, appear in other environments, or spread to other behaviors.
Term
Effective
Definition
Improves behavior sufficiently to produce meaningful results for the participant.
Term
Positive Reinforcement
Definition
When a behavior is followed immediately by the presentation of a stimulus that increases the future frequency of the behavior under similar conditions.
Term
Negative Reinforcement
Definition
When a behavior is followed immediately by the termination of a stimulus that increases the future frequency of the behavior under similar conditions.
Term
Stimulus
Definition
Any physical change that affects an organism through its receptor cells.
Term
Stimulus Class
Definition
A group of stimuli that share specific common elements along formal, temporal, and/or functional dimensions.
Term
Behavior
Definition
Something a person does.
Term
Response Class
Definition
A group of responses of varying topography, all of which produce the same effect on the environment.
Term
Positive Punishment
Definition
When a behavior is followed immediately by the presentation of a stimulus that decreases the future frequency of the behavior under similar conditions.
Term
Automatic Reinforcement
Definition
Reinforcement that occurs independently of the social mediation of others.
Term
Negative Punishment
Definition
When a behavior is followed immediately by the removal of a stimulus that decreases the future frequency of the behavior under similar conditions.
Term
Shaping
Definition
The differential reinforcement of successive approximations to a terminal behavior.
Term
Functional Relation
Definition
When a well-controlled experiment reveals that a specific change in one event can reliably be produced by specific manipulations of another event.
Term
Extinction
Definition
To discontinue reinforcement of a previously reinforced behavior resulting in a decrease in the frequency of the behavior.
Term
Premack Principle
Definition
Making the opportunity to engage in a high-probability behavior contingent on the occurrence of a low-frequency behavior will function as reinforcement for the low-frequency behavior.
Term
Token Economy
Definition
A system where participants earn generalized conditioned reinforces as an immediate consequence for specific behaviors and exchange them later for backups.
Term
Conditioned Reinforcer
Definition
A previously neutral stimulus that functions as a reinforcer because of prior pairing with one or more reinforcers.
Term
Unconditioned Reinforcer
Definition
A stimulus change that functions as reinforcement even though the learner has no particular learning history with it.
Term
Variable Interval Schedule of Reinforcement
Definition
A schedule of reinforcement that provides reinforcement for the first correct response following the elapse of variable durations of time occurring in a random or unpredictable order.
Term
Fixed Interval Schedule of Reinforcement
Definition
A schedule of reinforcement in which reinforcement is delivered for the first response emitted following the passage of a fixed duration of time.
Term
Variable Ratio Schedule of Reinforcement
Definition
A schedule of reinforcement requiring a varying number of responses for reinforcement.
Term
Fixed Ratio Schedule of Reinforcement
Definition
A schedule of reinforcement requiring a fixed number of responses for reinforcement.
Term
Unconditioned Punisher
Definition
A stimulus change that acts as a punisher even though the learner has no particular learning history with it.
Term
Conditioned Punisher
Definition
A previously neutral stimulus that functions as a punisher because of prior pairing with one or more punishers.
Term
Stimulus Control
Definition
When a behavior occurs more frequently in the presence of a stimulus than in its absence.
Term
Discriminative Stimulus
Definition
A stimulus in the presence of which a particular response will be reinforced or punished.
Term
Echoic
Definition
Verbal operant involving a response that is evoked by a verbal discriminative stimulus that has point-to-point correspondence and formal similarity with the response.
Term
Mand
Definition
Verbal operant that is evoked by a motivating operation and specifies its own reinforcer.
Term
Tact
Definition
Verbal operant evoked by a nonverbal discriminative stimulus and followed by generalized conditioned reinforcement.
Term
Intraverbal
Definition
Verbal operant that is evoked by a verbal discriminative stimulus and that does not have point-to-point correspondence with that verbal stimulus.
Term
DRA
Definition
Differential Reinforcement of an Alternative Behavior - stopping the reinforcement for an existing behavior while reinforcing a desirable alternative behavior.
Term
DRI
Definition
Differential Reinforcement of an Incompatible Behavior -stopping the reinforcement for an existing behavior while reinforcing a behavior that is incompatible.
Term
DRO
Definition
Differential Reinforcement of Other Behavior – reinforcement is contingent on the absence of the problem behavior during a specific time.
Term
Behavior Contrast
Definition
When a change in one component of a multiple schedule that increases or decreases the rate of responding on that component is accompanied by a change in the response rate in the opposite direction on the other, unaltered component of the schedule.
Term
Matching Law
Definition
The allocation of responses to choices available on concurrent schedules of reinforcement are distributed in proportions that match the rates of reinforcement received from each choice alternative.
Term
Behavior Momentum
Definition
The tendency of behavior to persist following changes in environmental conditions.
Term
Errorless Learning
Definition
After an Sd is delivered, an immediate prompt is provided that decreases the opportunity for incorrect choice selection.
Term
Stimulus Generalization
Definition
The behavioral contingencies in the presence of one stimulus affect the frequency of the response in the presence of another stimulus.
Term
Response Generalization
Definition
The extent to which a learner emits untrained responses that are functionally equivalent to the trained target behavior.
Term
Behavior Cusps
Definition
A behavior that has consequences that extend well beyond the specific change itself because it exposes the person to new environments, reinforcers, contingencies, responses, and stimulus controls.
Term
Motivating Operation
Definition
An environmental variable that (a) alters the reinforcing or punishing effectiveness of a stimulus,; and (b) alters the current frequency of all behavior that has been reinforced or punished by that stimulus.
Term
Task Analysis
Definition
The process of breaking a complex skill of series of behaviors into smaller, teachable, units.
Term
Chaining
Definition
A sequence of discrete responses where each response produces a stimulus change that simultaneously serves as a conditioned reinforcer for the response it produced and an Sd for the next response in the sequence.
Term
Fading
Definition
A procedure for transferring stimulus control in which features of an antecedent stimulus controlling a behavior are gradually changed to a new stimulus while maintaining the current behavior.
