Stimulus Control and Verbal Behavior Flashcards

Which procedure involves gradually removing prompts across trials to transfer stimulus control to natural cues?

Answer: Stimulus fading

Stimulus fading systematically removes or dims artificial prompts so that the natural discriminative stimulus gains full control over the response.

A child fills in 'twinkle twinkle little ___' when prompted by the phrase. Which verbal operant best describes this response?

Answer: Intraverbal

An intraverbal is a verbal response to a verbal antecedent where the response does not match the antecedent (non-echoing, non-transcriptive).

Equivalence-based instruction capitalizes on which property of stimulus classes?

Answer: Transitivity, reflexivity, and symmetry

Derived stimulus relations (equivalence) require demonstrations of reflexivity (A=A), symmetry (if A→B then B→A), and transitivity (if A→B and B→C then A→C).

In errorless learning, a prompt is delivered _____ the natural SD to ensure the learner responds correctly from the start.

Answer: Before or simultaneously with

Errorless procedures present the prompt immediately before or at the same time as the SD so the learner makes the correct response before errors can occur.

Which schedule of reinforcement produces a high, steady response rate and is most resistant to extinction?

Answer: Variable ratio

Variable ratio schedules produce the highest and most persistent rates of responding because reinforcement is unpredictable in number.

Blocking, in stimulus control research, refers to:

Answer: Preventing a new stimulus from gaining discriminative control due to a pre-trained stimulus

Blocking occurs when prior training with one stimulus prevents a second stimulus, presented in compound, from acquiring control over the response.
