During a clinical session, Mr. Star requires several prompts to initiate conversation. He stares at his food during meals, and she has to tell him to pick up his utensils to start eating. Which lobe is affected?

• A. Frontal lobe
• B. Parietal lobe
• C. Temporal lobe
• D. Occipital lobe

Answer: (A)

Initiation of voluntary social and motor behavior is governed mainly by the frontal lobes, especially the prefrontal regions involved in executive function and motivation. When these areas are affected, people can show abulia—a reduced drive to act or speak—so they need external prompts to begin tasks or conversations. In this scenario, needing prompts to start talking and to pick up utensils to begin eating reflects this loss of spontaneous initiation and goal-directed behavior typical of frontal lobe dysfunction. The behavior of staring at food during meals further supports a lack of initiative rather than a sensory or perceptual problem.

If the issue were in other lobes, the presentation wouldn’t center on initiating actions. Parietal lobe damage tends to disrupt sensory integration or praxis in more goal-directed tasks, temporal lobe changes relate to memory and language, and occipital lobe issues affect vision.
