The purpose of the present study was to examine the changes of the tickle sensation reflected in effects of the direction of attention to one's own body (Exp. 1) and the expectation of the experimenter's gestures (Exp. 2). In Exp. 1, for 15 subjects, when tickled on their own foot soles, the tickle sensation was not significantly changed by attending to the stimulus and to one's own sole. These results suggested the importance of instructions. In Exp. 2, 6 subjects were tickled and were required to report their experience while they looked at the experimenter's gestures and were tickled. Although the subjects' stimulations were unaffected by looking at the gestures, the tactual stimulus elicited a tickle sensation. From these results, quantitative and qualitative differences in subjects' tickle sensation may be identified.
本研究的目的是考察在关注自身身体方向的影响（实验1）和对实验者手势的预期（实验2）中所反映出的瘙痒感的变化。在实验1中，对15名受试者自己的脚底进行挠痒时，通过关注刺激和自身脚底，瘙痒感没有显著变化。这些结果表明了指导语的重要性。在实验2中，对6名受试者进行挠痒，并要求他们在看着实验者的手势并被挠痒时报告自己的感受。尽管受试者的刺激不受观看手势的影响，但触觉刺激引发了瘙痒感。从这些结果中，可以识别出受试者瘙痒感在数量和质量上的差异。
