In the context of schizophrenia, people with the condition termed _________ show striking impairment in motor activity.

A) catatonia
B) kinesthesis
C) hypogeusia
D) hyperphagia

Catatonia is a condition in which individuals show significant changes in motor behavior, including slowed movements or complete immobility (stupor), repetitive, purposeless movements (stereotypy), and rigid or contorted postures. These symptoms can significantly impact a person's ability to function in daily life and are often seen in individuals with schizophrenia. Kinesthesis refers to the perception of the position and movement of the body, which is typically not impaired in schizophrenia. Hypogeusia refers to a decreased sense of taste, and hyperphagia refers to excessive eating, neither of which are directly related to motor impairment in schizophrenia.
