Mr. Jones demonstrates how to wash his access. This is an example of which adult learning principle?

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

Answer: (D)

This item tests the psychomotor domain—the ability to perform a physical skill. Demonstrating how to wash his access involves executing precise hand movements, following a sequence, and applying sterile technique. The learner then practices the steps to develop muscle memory, accuracy, and safety, which are the hallmark of psychomotor learning. Cognitive learning would be about understanding why each step is performed, affective about attitudes toward the task, and social about interaction with others; those aspects aren’t the primary focus when the goal is to perform a hands-on skill like washing an access.
