Which adult learning principle is demonstrated when a patient verbalizes procedural steps for operating a dialysis-related task?

• A. Psychomotor
• B. Affective
• C. Social
• D. Cognitive

Answer: (D)

Verbalizing procedural steps shows the brain actively processing and organizing information about how to perform a task. When a patient puts the steps into words, they’re demonstrating understanding, sequencing, and the ability to recall and articulate how to operate a dialysis-related task. That mental processing and expression of knowledge is the cognitive domain in adult learning.

If the same scenario involved actually performing the movements, that would illustrate psychomotor skills. If it involved expressing feelings, attitudes, or motivation toward the task, that would be affective. If it involved interactions with others or teamwork, that would be social. Here, the act of describing the steps focuses on understanding and verbalizing knowledge, which is why the correct choice is the cognitive domain.
