Equivalence-Based Instruction

These flashcards cover key concepts from Chapter 19 on equivalence-based instruction.

Class expansion

A new member is added to a demonstrated stimulus equivalence class as the result of teaching a new conditional discrimination.

Class merger

Independent equivalence classes are combined as the result of teaching a new but interrelated conditional discrimination.

Class-specific reinforcement

A match-to-sample procedure in which not only is the correct comparison choice conditional on the sample stimulus, but the type of consequence delivered is, too.

Conditional discrimination

The role of one discriminative stimulus is conditional on the presence of another stimulus.

Contextual control

The context that controls a particular type of relational responding.

Derived stimulus relations

Relations between stimuli that appear without having been learned or trained specifically.

Emergent stimulus relations

Stimulus relations that are not taught directly but emerge as an indirect function of related instruction or experience.

Equivalence-class formation

The emergence of accurate responding to untrained and nonreinforced stimulus-stimulus relations following the reinforcement of responses to some stimulus-stimulus relations.

Higher-order operant class

Behavior defined in terms of general relations between antecedents and responses, rather than in terms of specific stimuli and responses.

Reflexivity

Selecting a comparison stimulus that is the same as the sample stimulus without direct training.

Simple discrimination

Produced within a three-term contingency, which consists of a prior stimulus, a response, and a reinforcer.

Stimulus-control topographies

Refers to two different forms of stimulus control that can result from MTS procedure involving one sample stimulus and two comparison stimuli.

Stimulus equivalence

Following training of a few discriminations between arbitrary stimuli, additional relations between the stimuli emerge without direct training.

Symmetry

Demonstrating the bidirectionality of equivalent sample and comparison stimuli without direct training.

Transfer of function

The functions of a stimulus in a relational network are altered based on how the stimulus is related to other stimuli.

Transitivity

A derived relation that emerges as a product of training two other equivalent relations.
