Abstract
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. and/or vis.) within an observation interval. The facility includes an observer's 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.Keywords
