Interaction with other sensory information is important for prediction of tactile events. Recent studies have reported that the approach of visual information toward the body facilitates prediction of subsequent tactile events. However, the processing of tactile events is influenced by multiple spatial coordinates, and it remains unclear how this approach effect influences tactile events in different spatial coordinates, i.e., spatial reference frames. We investigated the relationship between the prediction of a tactile stimulus via this approach effect and spatial coordinates by comparing ERPs. Participants were asked to place their arms on a desk and required to respond tactile stimuli which were presented to the left (or right) index finger with a high probability (80%) or to the opposite index finger with a low probability (20%). Before the presentation of each tactile stimulus, visual stimuli approached sequentially toward the hand to which the high-probability tactile stimulus was presented. In the uncrossed condition, each hand was placed on the corresponding side. In the crossed condition, each hand was crossed and placed on the opposite side, i.e., left (right) hand placed on the right (left) side. Thus, the spatial location of the tactile stimulus and hand was consistent in the uncrossed condition and inconsistent in the crossed condition. The results showed that N1 amplitudes elicited by high-probability tactile stimuli only decreased in the uncrossed condition. These results suggest that the prediction of a tactile stimulus facilitated by approaching visual information is influenced by multiple spatial coordinates.

多个空间坐标会影响通过视觉刺激促进触觉事件的预测。

与其他感觉信息的相互作用对于预测触觉事件很重要。最近的研究报告说,向身体发出视觉信息的方法有助于预测随后的触觉事件。然而,触觉事件的处理受到多个空间坐标的影响,并且尚不清楚该方法的效果如何影响不同空间坐标即空间参考系中的触觉事件。通过比较ERP,我们调查了通过这种方法效果的触觉刺激预测与空间坐标之间的关系。要求参与者将手臂放在桌子上,并要求对触觉刺激做出响应,以极高的概率(80%)出现在左(或右)食指或以低概率(20%)出现在相对的食指上。在呈现每个触觉刺激之前,视觉刺激顺序地向呈现高概率触觉刺激的手靠近。在未交叉的条件下,每只手放在相应的一侧。在交叉状态下,将每只手交叉并放在相反的一侧,即,左(右)只手放在右侧(左)。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。视觉刺激依次向呈现高概率触觉刺激的手靠近。在未交叉的条件下,每只手放在相应的一侧。在交叉状态下,将每只手交叉并放在相反的一侧,即,左(右)只手放在右侧(左)。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。视觉刺激依次向呈现高概率触觉刺激的手靠近。在未交叉的条件下,每只手放在相应的一侧。在交叉状态下,将每只手交叉并放在相反的一侧,即,左(右)只手放在右侧(左)。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。在未交叉的条件下,每只手放在相应的一侧。在交叉状态下,将每只手交叉并放在另一侧,即,左(右)手放在右(左)侧。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。在未交叉的条件下,每只手放在相应的一侧。在交叉状态下,将每只手交叉并放在相反的一侧,即,左(右)只手放在右侧(左)。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。因此,触觉刺激和手的空间位置在非交叉状态下是一致的,在交叉状态下是不一致的。结果表明,高概率触觉刺激引起的N1振幅仅在非交叉条件下降低。这些结果表明,通过接近视觉信息促进的触觉刺激的预测受多个空间坐标的影响。
