Perseverative interference in monkeys following selective lesions of the inferior prefrontal convexity
- 468 Downloads
Monkeys with lesions of the inferior frontal convexity were impaired relative to controls in retaining an auditory frequency differentiation (although subsequent thresholds were normal) and in learning object and spatial reversals. Performance was characterized by perseverative interference, a frontal symptom which now seems attributable to damage to the inferior convexity.
