We found that a hand posture with the palms together located just below the stream/bounce display could increase the proportion of bouncing perception. This effect, called the hands-induced bounce (HIB) effect, did not occur in the hands-cross condition or in the one-hand condition. By using rubber hands or covering the participants' hands with a cloth, we demonstrated that the visual information of the hand shapes was not a critical factor in producing the HIB effect, whereas proprioceptive information seemed to be important. We also found that the HIB effect did not occur when the participants' hands were far from the coincidence point, suggesting that the HIB effect might be produced within a limited spatial area around the hands.
我们发现，手掌并拢且位于水流/弹跳显示下方的手部姿势能够增加弹跳感知的比例。这种效应被称为手部诱发弹跳（HIB）效应，在双手交叉条件或单手条件下并未出现。通过使用橡胶手或用布覆盖参与者的手，我们证明了手部形状的视觉信息并非产生HIB效应的关键因素，而本体感觉信息似乎很重要。我们还发现，当参与者的手远离重合点时，HIB效应不会出现，这表明HIB效应可能在手部周围有限的空间区域内产生。
