SOME FACTORS INFLUENCING THE EFFECTIVE AUDITORY INTENSIVE DIFFERENCE LIMEN

Abstract

Research was undertaken to determine probability of detection of changes in a steady noise stimulus and probability of detection of louder noise pulses in a train of pulses under un alerted conditions over appreciable periods of time at different levels of discrimination difficulty. Changes in a steady stimulus were more readily detected than changes in pulses. At intermediate difficulty levels detections of changes in the steady stimulus declined with time; at intermediate and difficult levels detection of louder pulses declined with time. Progressive increases in latency were noted in some cases, and there was a general tendency for false detections to decline with time on task.
