摘要环境光的变化影响味觉强度感知。在一项旨在阐明这种效应的性质的实验中，48名学生每人品尝了27对柠檬酸样品，判断第二个样品相对于第一个样品的强度。四套不同的酸刺激的可辨别性，和三个条件的环境照明变化。一半的学生接受了系统的强化反应，其他人则没有。实验结果表明，当初级辨别任务相对困难时，被试会利用异质通道线索作为替代反应的基础。
Abstract Changes in ambient light have been reported to affect taste intensity perception. In an experiment designed to clarify the nature of this effect 48 Ss each tasted 27 pairs of citric acid samples, judging the intensity of the second sample relative to the first. Four sets of acid stimuli varying in discriminability were used, and three conditions of ambient illumination change. Half the Ss received systematic reinforcement of their responses, the others did not. Results suggest that Ss use hetero-modal cues as an alternative response basis when the primary discrimination task is relatively difficult.
