An experiment was conducted to determine the pre- and posttest performance of subjects on a signal-detection task for the following three experimental conditions: sensory isolation, sensory alertness, and sensory relaxation. All subjects were assessed on 36 pretest and 36 posttest trials. Each block of 36 trials consisted of 12 "strong signals," 12 "weak signals," and 12 "no signals." Exposure durations for each experimental condition lasted for one hour. Analyses showed significant improvements in hits from the pretest trials to the posttest trials on the "strong" and "weak signals" for the sensory isolation condition. Moreover, on the posttest "weak signal" trials, subjects in the sensory isolation condition scored a significantly greater number of hits than did those in the sensory alertness or sensory relaxation conditions. It was concluded that sensory isolation produces perceptual enhancement, as measured by a signal-detection task.
进行了一项实验，以确定在以下三种实验条件下，受试者在信号检测任务中的测试前和测试后表现：感觉隔离、感觉警觉和感觉放松。所有受试者都在36次测试前和36次测试后试验中接受评估。每36次试验的一组包括12次“强信号”、12次“弱信号”和12次“无信号”。每种实验条件的暴露持续时间为一小时。分析表明，在感觉隔离条件下，从测试前试验到测试后试验，“强”和“弱信号”的击中率有显著提高。此外，在测试后“弱信号”试验中，感觉隔离条件下的受试者的击中次数显著多于感觉警觉或感觉放松条件下的受试者。得出的结论是，通过信号检测任务测量，感觉隔离会产生感知增强。
