Behavior Analysis: Discriminative Stimulus Concepts

Questions and Answers

What is a discriminative stimulus?

A stimulus in the presence of which responses of some type have been reinforced and in the absence of which the same type of responses have occurred and not been reinforced.

What is a stimulus delta (S-Delta)?

A stimulus in the presence of which a given behavior has not produced reinforcement in the past.

What does stimulus control refer to?

When the rate, latency, duration, or amplitude of a response is altered in the presence of an antecedent stimuli.

What is stimulus generalization?

When an antecedent stimulus has a history of evoking a response that has been reinforced in its presence, similar stimuli evoke the same behavior. Signup and view all the answers

What is stimulus discrimination?

Requires one behavior and two antecedent stimulus conditions. Responses are reinforced in the presence of one stimulus, the SD, but not in the presence of another stimulus, the S-Delta. Signup and view all the answers

Study Notes

Discriminative Stimulus

Refers to a specific stimulus where responses have been reinforced in its presence.
In its absence, the same responses do not receive reinforcement.

Stimulus Delta (S-Delta)

Represents a stimulus where a particular behavior has not resulted in reinforcement previously.

Stimulus Control

Describes changes in the rate, latency, duration, or amplitude of a response based on antecedent stimuli presence.

Stimulus Generalization

Occurs when stimuli sharing similar physical properties with a controlling antecedent elicit a response that has been reinforced before.

Stimulus Discrimination

Involves one behavior responding to two antecedent stimuli: reinforcement occurs with the SD but not with the S-Delta.

Concept Formation

A more complex aspect of stimulus control that requires both generalization within a stimulus class and discrimination across different classes.

Antecedent Stimulus Class

Consists of a group of stimuli that exhibit a common relational characteristic.

Stimulus Equivalence

Refers to accurate responding to untrained stimulus-stimulus relations after reinforcement of responses to specific relations.

Testing for Stimulus Equivalence

Three methods include reflexivity (matching the same stimulus), symmetry (reversibility of the relation), and transitivity (if A=B and B=C, then A=C).

Generalized Identity Matching

Another term for reflexivity; involves matching a stimulus to itself.

Matching-to-Sample

A procedure used to explore conditional relations and assess stimulus equivalence.

Prompts

Supplemental antecedent stimuli that help elicit a correct response in the presence of an SD, aiming for eventual control by natural stimuli.

Major Forms of Response Prompts

Includes verbal instructions, modeling, and physical guidance as effective prompting methods.

Procedures for Transferring Stimulus Control

Involves strategies such as most-to-least prompts, graduated guidance, least-to-most prompts, and time delay to shift control from prompts to natural stimuli.
