Tommy is frequently asking his parents questions, and they want to decrease his behavior to an acceptable level. Tommy's parents tell him that they will answer a question only if it has been at least 10 minutes since his last question. If Tommy asks a question before the 10-minute interval is up, his parents do not reinforce his behavior with an answer to the question? Which DRL variation are Tommy's parents using?

A) full-session DRL
B) interval DRL
C) spaced-responding DRL
D) secondary DRL

C) spaced-responding DRL          

Explanation:

Spaced-responding DRL: In psychology, the term "spaced-responding DRL" is described as one of the variants of the "standard DRL" procedure and is being utilized whereby reinforcement is given following a specific response and if that specific response has been isolated from the former response through at least a fixed-minimum "time interval".

In the question above, the given statement represents that Tommy's parents are using spaced-responding DRL.
