The interaction between vision and touch, known as the crossmodal congruency effect, has been extensively investigated in several research studies. Recent studies have revealed that the crossmodal congruency effect involves body representations. However, it is unclear how bodily information (e.g., location, posture, motion) is linked to visual and tactile inputs. Three experiments were conducted to investigate this issue. In Experiment 1, participants performed a crossmodal congruency task in which both their hand appearance and the motor trajectories were left-right reversed. The results showed that the crossmodal congruency effect was not observed in the reversal condition, whereas participants showed significant crossmodal congruency in the control condition, in which there was no visual manipulation of the hand. In Experiments 2 and 3, where either the hand appearance or motor trajectory was left-right reversed individually, a significant crossmodal congruency effect was observed. This study demonstrated that visual manipulation of hand appearance and motor trajectories both affected the crossmodal congruency effect, although neither showed a dominant effect that solely altered the crossmodal congruency effect. The present results provide insights into the relationship between visual-tactile interactions and bodily information.
视觉和触觉之间的相互作用，即跨模态一致性效应，在许多研究中都得到了广泛的研究。最近的研究表明，跨模态一致性效应涉及身体的表现。然而，目前尚不清楚身体信息（例如位置、姿势、运动）是如何与视觉和触觉输入联系起来的。进行了三项实验来研究这个问题。在实验 1 中，参与者在一个跨模态一致性任务中完成了实验，在这个任务中，他们的手的外观和运动轨迹都左右反转。结果表明，在反转条件下没有观察到跨模态一致性效应，而在控制条件下，参与者表现出显著的跨模态一致性，在手的外观没有视觉操作的情况下。在实验 2 和 3 中，单独地对手的外观或运动轨迹进行左右反转，观察到了显著的跨模态一致性效应。本研究表明，视觉对手的外观和运动轨迹的操作都会影响跨模态一致性效应，尽管两者都没有表现出单独改变跨模态一致性效应的主导效应。本研究结果为视觉-触觉相互作用与身体信息之间的关系提供了新的认识。
