ABA Stimulus Control & Discrimination Training 2

Question 1

A stimulus generalization gradient shows the relationship between stimuli along a dimension and response rate.
What typically happens to response rate as stimuli become more dissimilar to the original SD?

Accepted Answer

Response rate decreases as stimuli become less similar to the SD

Answer

Response rate increases monotonically

Answer

Response rate remains constant regardless of similarity

Answer

Response rate increases only for stimuli on one side of the SD

Question 2

The peak shift effect refers to a phenomenon in which, after discrimination training, the peak of the generalization gradient:

Accepted Answer

Shifts away from the SΔ beyond the original SD

Answer

Remains at the SD used during training

Answer

Shifts toward the SΔ

Answer

Flattens so all stimuli produce equal response rates

Question 3

A conditional discrimination requires that the learner:

Accepted Answer

Choose among comparison stimuli based on the relationship to a sample stimulus

Answer

Respond to the SD regardless of contextual stimuli

Answer

Generalize responses to all members of a stimulus class

Answer

Emit the response in the presence of any novel stimulus

Question 4

Which concept describes the phenomenon where a stimulus that was not present during conditioning can block the development of stimulus control by a second stimulus?

Accepted Answer

Blocking

Answer

Stimulus overshadowing

Answer

Behavioral contrast

Answer

Stimulus equivalence

Question 5

A student with autism responds correctly to the teacher's question only when the teacher is wearing a red shirt, not any other shirt. This is an example of:

Accepted Answer

Overselective stimulus control

Answer

Behavioral contrast

Answer

Multiple schedule performance

Answer

Derived relational responding

Question 6

Transfer of stimulus control refers to a process in which:

Accepted Answer

Control over behavior is shifted from a prompt to the natural discriminative stimulus

Answer

A response trained under one schedule generalizes to a new schedule

Answer

Reinforcement is transferred from an artificial to a natural reinforcer

Answer

A behavior is transferred from one topography to another

Question 7

In a match-to-sample (MTS) procedure, identity matching differs from arbitrary matching in that:

Accepted Answer

Identity matching requires selecting a comparison that is physically identical to the sample

Answer

Identity matching uses three comparison stimuli while arbitrary matching uses two

Answer

Arbitrary matching is only used with vocal behavior

Answer

Identity matching relies solely on reinforcement history without antecedent control
