Lack of motor responses is described as which term?

• A. Mutism
• B. Stupor
• C. Catatonic excitement
• D. Negative Symptoms

Answer: (B)

Lack of motor responses points to a severe reduction in psychomotor activity known as stupor. In this state, a person may become entirely unresponsive to external stimuli, remaining motionless and mute for extended periods. This is a hallmark feature of catatonia, where motor responsiveness is profoundly diminished. Mutism describes absence of speech and can occur within a stuporous state, but it specifically refers to not speaking rather than the broader lack of movement and responsiveness. Catatonic excitement, by contrast, involves excessive, purposeless motor activity and agitation, opposite to stupor. Negative symptoms denote a chronic reduction in normal functions such as motivation, speech, and affect, which can include slowed movement but do not capture the complete immobility and unresponsiveness seen in stupor.
