Difficult Turned Easy: Suggestion Renders a Challenging Visual Task Simple
研究发现，对催眠暗示高度敏感的成年人能够通过暗示成功幻觉出移动物体上的视觉遮挡物，从而将原本困难的视觉任务变得简单，表明暗示可以为感官输入添加感知信息。
Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at least in some people, suggestions can add perceptual information to sensory input. This observation adds meaningful weight to theoretical, clinical, and applied aspects of the brain and psychological sciences.
