Pagination or Media Count:
The facility described allows presentation of visual, auditory, or bisensory signals for the study of forced-choice signal detection. Means are provided for informing the observer, prior to each trial, of the signal mode he should expect on that trial. Considerable flexibility is provided for the scheduling of intermittent noise aud. andor vis. within an observation interval. The facility includes an observers station within an anechoic chamber and a control unit in a separate room. Data collection sessions are fully automated. The control system reads a paper tape input and produces a paper tape output. Input stimulus scheduling tapes are generated, and output data tapes are processed, by a PDP-1 computer.
