摘要
工业技术的发展,特务是复杂的武器系统(如战斗机)的发展,曾经对人提出信号过多、过速,反应过于复杂,要求传递的信息率过高,超出人的一般辨别和操作能力的所谓“超负荷”问题。近年来,由于自动化工程的发展,在人的负荷方面提出了另一方面的问题,即当人在信息传递和操作活动减至极少的条件下出现的所谓“低负荷”问题。“
Underloading is a situation in which the frequency of significant signals are very low.Signal detection was studied with intersignal intervals (ISI) varying from 1 to 90 minutesand with choice reactions (CR) varying from 2 to 8 signals. The main results were asfollows: 1. The phenomenon of "very long signal detection time" (over 20 sec. to 15 mi-nutes) under underloading conditions was observed. The probability of this phenomenonwas of a linear inclined function of ISI. As CR declined, the probability of the abovephenomenon also declined, but it could never be eliminated. 2. Under underloading conditions the logarithms of information transmissing werea linear declined function of ISI.
