A neuropsychological technique used to detect simulated memory impairment, often in forensic psychiatric or clinical practice. The subject is shown a simple visual set of 15 elements arranged in an easy-to-remember order. After a short time of presentation, he is asked to reproduce or name the elements. Since the task is designed for normal memory capabilities, a very low result may indicate a deliberate underestimation of indicators (simulation), and not real disorders. It is usually used in conjunction with other confidence tests and cognitive techniques.
