看到自己的身体（直接或间接）可以影响视觉触觉跨模态交互。以前，它已被证明，即使是看一个简单的线条画的手也可以调制这样的跨模态的相互作用，如果查看图片的手不知何故启动表示自己的手。然而，除了看到一张象征性的手的图片之外，其他因素可能已经调制了先前研究中报道的跨模态相互作用。在本研究中，我们研究了跨通道调制效应，观看五种不同的视觉图像（手的照片，手的线条画，汽车的线条画，U形，椭圆形）触觉性能。参与者提出了快速的歧视反应的位置，简短的振动触觉目标的尖端或基地，他们的左手食指，而试图忽略视觉干扰提出的左或右的中央固定。我们比较了五种不同的视觉图像叠加在视觉干扰物上时引起的视觉触觉一致性效应。参与者的触觉识别性能调制到一个显着更大的程度上通过观看手的照片比当观看手的轮廓图。没有这样的跨模态一致性的影响，报告在任何其他条件。因此，这些结果表明，视觉触觉的相互作用是专门调制的图像的手，而不仅仅是任何简单的方向线索，可以提供的图像的手。
Seeing one’s own body (either directly or indirectly) can influence visuotactile crossmodal interactions. Previously, it has been shown that even viewing a simple line drawing of a hand can also modulate such crossmodal interactions, as if viewing the picture of a hand somehow primes the representation of one’s own hand. However, factors other than the sight of a symbolic picture of a hand may have modulated the crossmodal interactions reported in previous research. In the present study, we examined the crossmodal modulatory effects of viewing five different visual images (photograph of a hand, line drawing of a hand, line drawing of a car, an U-shape, and an ellipse) on tactile performance. Participants made speeded discrimination responses regarding the location of brief vibrotactile targets presented to either the tip or base of their left index finger, while trying to ignore visual distractors presented to either the left or right of central fixation. We compared the visuotactile congruency effects elicited when the five different visual images were presented superimposed over the visual distractors. Participants’ tactile discrimination performance was modulated to a significantly greater extent by viewing the photograph of a hand than when viewing the outline drawing of a hand. No such crossmodal congruency effects were reported in any of the other conditions. These results therefore suggest that visuotactile interactions are specifically modulated by the image of the hand rather than just by any simple orientation cues that may be provided by the image of a hand.
