Trace Reflex Formation in Senescence and Senility

Conditionability of the brain-damaged patient, measured on skeleto-muscular and autonomic conditioned responses, was shown to be greatly reduced in comparison with the conditionability of patients suffering from psychogenic disturbances [11, 12, 21]. A decrease in conditionability with age was also demonstrated utilizing the galvanic skin response (GSR) [3] and the conditioned-eyelid method [4], In order to assess the relative contributions of age. and brain damage on the decrease in conditionability of senile, brain-damaged individuals, we compared their results with those of senescent individuals [22].
