现实世界的场景感知通常会涉及不止一种感觉方式。在这里，我们研究了熟悉物体场景的视觉、触觉和跨模态识别。在三个实验中，参与者首先了解了在平台上随机排列物体的场景。学习后，实验者交换场景中两个物体的位置，参与者的任务是识别两个交换的物体。在实验 1 中，我们发现当学习和测试之间感觉模态和场景方向发生变化时，场景识别性能会受到影响。跨模式性能的成本并不是由于参与者对对象进行口头编码（实验 2），也不是由于触觉和视觉学习期间对象的串行和并行编码之间的差异（实验 3）。相反，我们的研究结果表明，空间的视觉和触觉表征之间的差异可能会影响对这些模式中物体场景的识别。
Real-world scene perception can often involve more than one sensory modality. Here we investigated the visual, haptic and crossmodal recognition of scenes of familiar objects. In three experiments participants first learned a scene of objects arranged in random positions on a platform. After learning, the experimenter swapped the position of two objects in the scene and the task for the participant was to identify the two swapped objects. In experiment 1, we found a cost in scene recognition performance when there was a change in sensory modality and scene orientation between learning and test. The cost in crossmodal performance was not due to the participants verbally encoding the objects (experiment 2) or by differences between serial and parallel encoding of the objects during haptic and visual learning, respectively (experiment 3). Instead, our findings suggest that differences between visual and haptic representations of space may affect the recognition of scenes of objects across these modalities.
