【 摘 要 】

The current program of research tests the following main hypotheses: 1) Synesthetic correspondence is an amodal property that serves to bind intersensory signals and manipulating this correspondence between pairs of audiovisual signals will affect performance on a temporal order judgment (TOJ) task; 2) Manipulating emphasis during a TOJ task from spatial to temporal aspects will strengthen the influence of task-irrelevant auditory signals; 3) The degree of dimensional overlap between audiovisual pairs will moderate the effect of synesthetic correspondence on the TOJ task; and 4) There are gaps in current perceptual theory due to the fact that synesthetic correspondence is a potential confound that has not been sufficiently considered in the design of perception research. The results support these main hypotheses. Finally, potential applications for the findings presented here are discussed.
