Mean number of errors (maximum = 48) for patients and controls subjects high selection items (filled bars) and low selection items (unfilled bars). Patients with left IFG lesions made more errors (omissions and non-verb responses) generating verbs for high selection items (e.g., cat), but performed comparably to control subjects for low selection items (e.g., scissors), interaction F = 27.37, P < 0.01.
