Which of the following is a characteristic of apraxia?

Apraxia is primarily characterized by difficulty in movement execution. This neurological condition affects an individual’s ability to perform purposeful movements despite having the physical ability and desire to do so. People with apraxia may understand the command to perform a task, but they struggle to coordinate the movements required to carry it out.

The other characteristics listed pertain to different conditions: the inability to recognize faces is associated with prosopagnosia, while poverty of speech relates to conditions affecting language production and can be seen in aphasia. Excessive verbosity, or logorrhea, typically occurs in certain psychiatric symptoms or conditions such as mania. Thus, the defining feature of apraxia directly relates to the challenges in executing movements, making the choice regarding difficulty in movement execution the correct answer.
