Abstract:
Crossmodal correspondences refer to the systematic associations often found across seemingly unrelated sensory features from different sensory modalities. Such phenomena constitute a universal trait of multisensory perception even in non-human species, and seem to result, at least in part, from the adaptation of sensory systems to natural scene statistics. Despite recent developments in the study of crossmodal correspondences, there are still a number of standing questions about their definition, their origins, their plasticity, and their underlying computational mechanisms. In this paper, I will review such questions in the light of current research on sensory cue integration, where crossmodal correspondences can be conceptualized in terms of natural mappings across different sensory cues that are present in the environment and learnt by the sensory systems. Finally, I will provide some practical guidelines for the design of experiments that might shed new light on crossmodal correspondences.
摘要:
交叉模态对应关系是指通常在来自不同感觉方式的看似无关的感觉特征中发现的系统关联。即使在非人类物种中,这种现象也构成了多感官感知的普遍特征,似乎结果,至少在某种程度上,从感官系统到自然场景统计的适应。尽管交叉模态对应的研究最近取得了进展,关于它们的定义仍然存在许多问题,他们的起源,它们的可塑性,以及它们潜在的计算机制。在本文中,我将根据当前对感觉线索整合的研究来回顾这些问题,其中,跨模态对应关系可以根据环境中存在并由感官系统学习的不同感官线索的自然映射来概念化。最后,我将为实验设计提供一些实用指南,这些指南可能会为跨模态对应关系提供新的思路。
