The perception of time and space are fundamental cognitive abilities, yet how they interact remains a subject of debate. One major theory posits an asymmetric relationship, where space influences time but not vice-versa, while another argues for a symmetric, bidirectional influence.
This project aims to resolve this debate by adopting a developmental and cross-modal perspective. The core objective is to investigate how the mutual interferences between time and space perception evolve from childhood to adulthood (ages 5-8 and adults) and how these interactions differ across sensory modalities (vision and audition). This thesis will (1) chart the developmental trajectories of time-space interference in separate visual and auditory tasks, (2) investigate how spatial uncertainty modulates these interferences, and (3) implement a novel experimental paradigm to systematically compare the influence of modality. By comparing age groups and sensory modalities, this project seeks to provide definitive evidence for the nature of time-space processing, contributing to a more unified model of how humans perceive fundamental magnitudes.
