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

A stimulus class is a group of stimuli that are functionally equivalent — they evoke the same response or are related through common derived relations such as equivalence.

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

Symmetry means that if a directional relation A→B is trained, the reverse relation B→A emerges without additional training.

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

MET exposes learners to many varied examples of a concept, helping generalization occur to untrained stimuli that share the relevant features.

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

In progressive time delay, the interval between SD and prompt is systematically increased over sessions; in constant time delay, one fixed delay interval is used from the start after an initial zero-delay phase.

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

Behavioral contrast is an increase in response rate in one component of a multiple schedule when the reinforcement rate in the other component is decreased.
