ABA Stimulus Control & Discrimination Training 3

Question 1

A stimulus class is defined as a group of stimuli that:

Accepted Answer

All produce the same reinforced response or participate in the same derived relations

Answer

All share the same physical topography

Answer

Are always presented together during discrimination training

Answer

Have all been used as SDs in the learner's history

Question 2

Stimulus equivalence involves three behavioral tests: reflexivity, symmetry, and transitivity. Which of the following correctly describes symmetry?

Accepted Answer

If A is trained to relate to B, then B will also relate to A without direct training

Answer

If A=A, the stimulus is a member of its own equivalence class

Answer

If A relates to B and B relates to C, then A will relate to C

Answer

If A relates to B, the learner can sort A and B into the same physical category

Question 3

Multiple exemplar training (MET) is used in ABA primarily to:

Accepted Answer

Promote generalization by training across varied examples of the stimulus class

Answer

Reduce the number of SD-SΔ discriminations required

Answer

Prevent overselective stimulus control by removing prompts early

Answer

Establish derived relational responding in the absence of direct reinforcement

Question 4

A behavior analyst uses a time-delay procedure to promote transfer of stimulus control. What distinguishes a progressive time delay from a constant time delay?

Accepted Answer

Progressive time delay starts at zero seconds and the delay increases gradually; constant time delay uses one fixed delay interval throughout

Answer

Constant time delay starts at zero and increases; progressive time delay uses the same delay from the first trial

Answer

Progressive time delay never uses prompts; constant time delay uses the same prompt level

Answer

They are equivalent procedures distinguished only by reinforcement schedule

Question 5

Behavioral contrast occurs in a multiple schedule when reinforcement in one component is reduced or eliminated, resulting in:

Accepted Answer

Increased responding in the unchanged component

Answer

Decreased responding in both components simultaneously

Answer

Transfer of extinction to the remaining component

Answer

Generalization of extinction across all stimuli

Question 6

When designing programs to establish stimulus control, practitioners should ensure that the SD is salient and that irrelevant stimulus features are minimized. This principle is most directly aligned with which concept?

Accepted Answer

Saliency and attention to relevant dimensions

Answer

Behavioral momentum

Answer

Setting event manipulation

Answer

Response deprivation hypothesis

Question 7

A practitioner establishes a visual schedule for a client using picture symbols. Over time, the practitioner fades the pictures to text-only cards so that the written words guide behavior. This is an example of:

Accepted Answer

Stimulus shaping (stimulus fading)

Answer

Response cost

Answer

Chaining

Answer

Behavioral momentum
