Which of the following verbs would refer to a psychomotor domain?

The verb that refers to a psychomotor domain is "demonstrate." This term is specifically associated with the psychomotor domain of learning, which involves physical skills, coordination, and the execution of tasks that require motor skills. In the context of education and training, demonstrating indicates that a learner can perform a skill or activity effectively, showcasing their ability to apply what they have learned through practice.

The psychomotor domain emphasizes hands-on experience and the physical execution of learned skills, making "demonstrate" a perfect fit for this domain. Instructors often assess learners on their capacity to demonstrate skills as a measure of competency in areas like emergency medical services, where practical demonstrations are essential.

While "appreciate," "identify," and "know" pertain more to cognitive or affective domains—focusing on understanding, recognition, and emotional response—these verbs do not capture the physical skill aspect associated with psychomotor learning. Therefore, "demonstrate" is the most appropriate verb related to the psychomotor domain.
