- VARIABLE CRITERION ANALYSIS OF SIMPLE REACTION TIME DISTRIBUTIONS IN NORMAL, CHIASM-SECTIONED AND CHIASM-CALLOSUMSECTIONED MONKEYS (Macaca mulatta)
Description
Normal, chiasm-sectioned, split-brain monkeys (M. mulatta) were binocularly trained to press a lever after onset of a visual warning signal and to release it after various forperiods terminated by a second visual signal. The use of hand was restricted to one side. After training, they were monocularly tested in each of the eye-hand combinations. When ipsilateral eye-hand combination was used, significantly prolonged reaction times (RTs) were found in two of three chiasmsectioned and three of four split-brain monkeys, but in different hands. The distribution of RTs in these conditions was characterized by a group of extremly long RTs. Data were represented in the cumulative probability distributions, which were used to estimate the means and σ of the response criterion by an application of variable criterion model. Mean criterions of the split-brain monkeys were significantly higher than those of the chiasm-sectioned monkeys, which were not different from that of the normal monkey. Finally, an exponential growth function of sensory recruitment to these different criterions was demonstrated on a common units across the eight subjects. The results of these analysis imply that two components were involved in the delayed RTs appearing in these split-brain monkeys. One is related to the process of signal detection and the other to the process of response evocation.
