Cooper Chapter 19: Equivalence-Based Instruction

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

• Class Expansion

• Class Merger

• Transfer of Function

A stimulus set that must be held in common across a minimum of two conditional discriminations to provide a basis for all equivalence properties.

• Class Expansion

• Nodal Stimulus

• Stimulus control topographic

Occurs when teaching a new function for one member of an established equivalence class results in the same function holding for all members of the class

• Stimulus Control Topographic

• Contextual Control

• Transfer of Function

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

• Contextual Control

• Transfer of Function

• Class Merger

Refers to two different forms of stimulus control that can result from a match-to-sample procedure involving one sample stimulus and two comparison stimuli

• Transfer of Function

• Contextual Control

• Stimulus control topographic

A procedure for building new arbitrary conditional discriminations based on the robust finding that learners will select a novel comparison stimulus over a known one in the presence of a novel sample.

• Exclusion

• Class Merger

• Nodal Stimulus

a type of stimulus control requiring 3 levels of antecedent stimuli, such that the functions of the stimuli in conditional discrimination vary depending on the context

• Contextual control

• Stimulus Control

• Transitivity
