Abstract

Vision is the most accurate sense for spatial representation, whereas audition is for temporal representation. However, how different sensory modalities shape the development of spatial and temporal representations is still unclear. Here, 45 children aged 11–13 years were tested to investigate the abilities to evaluate spatial features of auditory stimuli during bisection tasks, while conflicting or non-conflicting spatial and temporal information was delivered. Since audition is fundamental for temporal representation, the hypothesis was that temporal information could influence auditory spatial representation development. Results show a strong interaction between the temporal and the spatial domain. Younger children are not able to build complex spatial representations when the temporal domain is uninformative about space. However, when the spatial information is coherent with the temporal information children of all age are able to decode complex spatial relationships. When spatial and temporal cues are conflicting, younger children are strongly attracted by the temporal instead of spatial information, while older participants result unaffected by the cross-domain conflict. These findings suggest that during development temporal representation of events is used to infer spatial coordinates of the environment, offering important opportunities for new teaching and rehabilitation strategies.
