The Colavita effect refers to the phenomenon wherein people tend to not respond to an auditory stimulus when a visual stimulus is simultaneously presented. Although previous studies have shown that endogenous modality attention influences the Colavita effect, whether the Colavita effect is influenced by endogenous spatial attention remains unknown. In the present study, we established endogenous spatial cues to investigate whether the size of the Colavita effect changes under visual or auditory cues. We measured three indexes to investigate the effect of endogenous spatial attention on the size of the Colavita effect. These three indexes were developed based on the following observations in bimodal trials: (a) The proportion of the “only vision” response was significantly higher than that of the “only audition” response; (b) the proportion of the “vision precedes audition” response was significantly higher than that of the “audition precedes vision” response; and (c) the reaction time difference of the “vision precedes audition” response was significantly higher than that of the “audition precedes vision” response. Our results showed that the Colavita effect was always influenced by endogenous spatial attention and that its size was larger at the cued location than at the uncued location; the cue modality (visual vs. auditory) had no effect on the size of the Colavita effect. Taken together, the present results shed light on how endogenous spatial attention affects the Colavita effect.

科拉维塔效应是指当视觉刺激同时出现时，人们往往对听觉刺激没有反应的现象。尽管之前的研究表明内源模态注意力会影响Colavita效应，但Colavita效应是否受到内源空间注意力的影响仍然未知。在本研究中，我们建立了内源性空间线索来研究 Colavita 效应的大小是否在视觉或听觉线索下发生变化。我们测量了三个指标来研究内生空间注意力对科拉维塔效应大小的影响。这三个指数是根据双模试验中的以下观察结果制定的： (a) “仅视觉”反应的比例显着高于“仅试听”反应的比例； (b) “视觉先于试听”的回答比例显着高于“试听先于视觉”的回答比例； (c)“视觉先于试听”反应的反应时间差异显着高于“试听先于视觉”反应。我们的结果表明，Colavita 效应总是受到内生空间注意力的影响，并且其大小在有提示的位置比在无提示的位置更大；提示方式（视觉与听觉）对 Colavita 效应的大小没有影响。综上所述，目前的结果揭示了内生空间注意力如何影响科拉维塔效应。
