In the Deese-Roediger-McDermott (DRM) procedure, participants are asked to remember a list of words like "bed, snooze, awake, tired, dream, rest," which are all words concerning the topic of sleep, although the word "sleep" is not on the list. After this procedure, participants .A) recall that they heard the word "sleep" on the original list, unless they are explicitly warned to be careful.
B) recall the word "sleep" being on the list even if they were explicitly warned to be careful.
C) are less confident in their recognition of "sleep" than in their recognition of words actually on the list.
D) are likely to say "sleep" was on the list in a recognition test but not during a recall test.

B). Recall the word "sleep" being on the list even if they were explicitly warned to be careful.

Explanation:

As per the given description, the participants would be able to 'recall the word 'sleep' even if they were explicitly warned to be careful' which is indicative of the false or untrue memory of humans due to which humans remember the events that never occurred actually.

Deese-Roediger-McDermott (DRM) procedure is demonstrated as the paradigm in cognitive psychology that studies the flawed memory of humans where the subjects are exposed to memorize a list of semantically associated words 'bed, awake, snooze, rest, dream, etc.' which are all associated to 'sleep', although not on the list but still remembered by the subjects that hints  the forged memory of humans. Thus, option B is the correct answer.

B.

Explanation:

Deese-Roediger McDermott (DRM) is a procedure that helps the psychologists study the phenomenon of false memory in cognitive psychology. This procedure was developed by James Deese in 1959 and extended by Henry Roediger and Kathleen McDermott in 1995.

According to this procedure, a subject is asked to remember a list of words as stated in the question and explicitly warned to be careful in remembering them. After being asked to name the list, they are subject to name the word 'sleep' as well even the word not being mentioned in the list. It is an example of false memory in which the person tends to falsely remember the word even after being explicitly warned to be careful.

So, the correct answer is option B.
