title: [Galvanic skin response as a reflection of the decision-making process when time is insufficient].
abstract: Amplitude and latency of skin galvanic response ( SGR ) was studied in 15 healthy subjects in two experimental programs. The first program demanded to perform a motor act as quickly as possible if all the three signals were the same, the second one demanded a motor act if at least one of the signals differed from the other two. Following series of signals were presented: 1--all the three signals being the same, 2--the first one differed from the others, 3,4--correspondingly, the second or the third signal differed from the others. The amplitude of SGR was found to increase, and its latency was found to decrease when the decision was taken under the conditions of time deficit. Thus, SGR reflects the process of decision taking rather than pretuning of the motor act.
