The DCIEM 'On Line' Serial Choice Reaction Timer (SCRT)

Abstract

An apparatus was developed to measure the psychomotor performance, namely, serial choice reaction time and movement time, of human subjects during exposure to various environmental stresses, such as, hypoxia and inert gas narcosis. It consists of a stimulus-response module (SRM) which is comprised of geometrically arranged sets of light emitting diodes (LEDs) and corresponding response buttons for extinguishing the LEDs as they are randomly lit. The apparatus is constructed in such a way that it permits visual stimulus intensity, the number of response alternatives and the average movement distance to be varied. A PDP 11/04 computer is used to control the apparatus and to record and analyze subjects' responses.
