Full Definition
Psychomotor refers to the relationship between psychological processes and voluntary motor behavior. In psychiatric contexts, this term is commonly used to describe observable changes in motor activity that reflect underlying mental states. Psychomotor agitation involves increased motor activity, restlessness, or inability to sit still, often associated with anxiety or mania. Psychomotor retardation involves slowed motor activity, reduced speech, and delayed responses, commonly seen in depression. Assessment of psychomotor activity is an essential component of mental status examination and can inform both diagnosis and treatment decisions.
