The article reviews the concept of crossmodal correspondences, which are consistent associations between stimulus features in different sensory modalities. These correspondences, such as high-pitched sounds being matched with small, bright objects, help the brain integrate multisensory information more effectively. The review highlights that crossmodal correspondences can be statistical, structural, or semantically mediated, and they play a crucial role in solving the crossmodal binding problem. The article discusses historical evidence for these correspondences, including early research on sound symbolism and crossmodal matching. It also examines how crossmodal correspondences influence human information processing, particularly in speeded classification tasks and unspeeded psychophysical tasks. The findings suggest that crossmodal congruency effects can modulate multisensory integration and temporal perception, indicating that these correspondences are not just cognitive phenomena but also have real-world implications for sensory integration.The article reviews the concept of crossmodal correspondences, which are consistent associations between stimulus features in different sensory modalities.
