BCBA Stimulus Control and Verbal Behavior 2

Question 1

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

Accepted Answer

Stimulus fading

Answer

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

Question 2

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

Accepted Answer

Intraverbal

Answer

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

Question 3

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

Accepted Answer

Transitivity, reflexivity, and symmetry

Answer

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).

Question 4

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

Accepted Answer

Before or simultaneously with

Answer

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.

Question 5

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

Accepted Answer

Variable ratio

Answer

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