Final answer:
Frontal lobe damage can lead to many cognitive and behavioral issues, such as difficulty in task execution, poor judgment, and personality changes, but not typically psychological inertia. Psychological inertia is usually associated with other brain disorders.
Step-by-step explanation:
Someone with frontal lobe damage might exhibit various symptoms, but one symptom they would not typically show is psychological inertia. The frontal lobe is key in functions related to personality, planning, judgment, and working memory. Damage to this area can lead to problems such as balance and posture issues, difficulty with planning and executing tasks, poor judgment, and personality changes. These symptoms can result from the disruption of the pathways between the frontal lobe and other brain structures, like the limbic system, which was the case with Phineas Gage. After his accident, Gage experienced significant changes in personality and emotional impulses control. However, psychological inertia, which is a lack of motivation or inability to initiate activities, is more commonly associated with other brain disorders rather than frontal lobe damage.
