研究了注意对振幅调制(AM)产生的适应的影响。在不同的实验条件下,在暴露于与言语干扰物同时呈现的适应性声音后,测量了听者对2kHz测试音的AM检测阈值。后效应的幅度,计算为适应引起的阈值的海拔,是较小的,当听众转移注意力从适配器的干扰声音比当他们出席了适配器。结果表明,无人值守的声音的AM可能没有得到充分的分析相比,出席的声音。
The effect of attention on adaptation produced by amplitude modulation (AM) was examined. In different experimental conditions, listeners' AM detection thresholds for a 2 kHz test tone were measured after exposing them to an adapting sound that was presented simultaneously with speech distractors. Magnitude of an aftereffect, calculated as the elevation of the thresholds caused by adaptation, was smaller when the listeners shift attention away from the adaptor to the distractor voice than when they attended to the adaptor. The results suggest that the AM of unattended sounds may not be fully analyzed compared to that of attended sounds.
