Damage to the frontal lobes appears to cause a deficit in the temporal organization of memory. M. P. McAndrews and B. Milner (1991) found that subject-performed tasks (SPTs), which involve the performance of actions with common objects, allowed frontal-lobe-damaged patients to circumvent this deficit and perform normally on recency judgments. The present investigation of the critical properties of SPTs compared the performance of frontal-lobe-damaged patients and healthy controls on recency judgments under 5 encoding conditions: SPT, naming, visual imagery, experimenter-performed tasks, and verbal elaboration. Patients' performance varied across encoding conditions, but controls' did not. Post hoc comparisons confirmed that patients performed significantly worse than controls across all encoding tasks except SPT. The findings help elucidate the nature of both SPTs and memory for temporal order.
