Abstract : The report describes the Purdue Manual-Verbal Response Tachistoscope, which is an instrument designed to measure intelligibility under conditions of distracting psychomotor activity. The intelligibility testing involves the use of a standardized intelligibility test and the psychomotor tasks consist of eye-hand coordination manipulations. The Purdue Manual-Verbal Response Tachistoscope was designed primarily for research and training in intelligibility under conditions involving high-level noise. Use of the instrument in combination with Navy Device 8-I, Portable Interphone Trainer makes possible the determination of the effect on voice communication of psychomotor tasks more or less complex in nature, requiring greater or less precision and rapidity of voluntary hand movements.
