视听时、空一致性对Pip-and-Pop效应的影响

多感觉整合遵循空间原则和时间原则, 有研究表明Pip-and-Pop效应产生的原因是多感觉整合, 那么Pip-and-Pop效应是否同样遵循空间原则和时间原则呢?本研究采用动态视觉搜索范式, 通过两个眼动实验考察空间一致性(实验1)和时间一致性(实验2)对Pip-and-Pop效应的影响。结果发现：(1)当视觉目标颜色变化伴随一个同侧的听觉刺激时所产生的Pip-and-Pop效应最大, 对侧条件没有发现Pip-and-Pop效应。(2)视听刺激同时呈现所产生的Pip-and-Pop效应最大, 随视听刺激呈现时间间隔的增加Pip-and-Pop效应逐渐减弱直至消失。结果表明, 视听时、空一致性对Pip-and-Pop效应具有调节作用, 这为多感觉整合在产生Pip-and-Pop效应中的作用提供了证据。

The impact of temporal and spatial consistency of audiovisual stimuli on Pip-and-Pop effect

Previous studies usually used the dynamic visual search paradigm to explore the Pip-and-Pop effect, which suggests that the Pip-and-Pop effect is influenced by multiple factors. But the impact of temporal and spatial consistency of audiovisual stimuli on the Pip-and-Pop effect is still controversial. In the present study, we applied the eye movement technology to the dynamic visual search paradigm to systematically investigate the impact of temporal and spatial consistency of audiovisual stimuli on the Pip-and-Pop effect. Based on the results of previous studies, we expected that the spatial and temporal consistency of audiovisual modulated the Pip-and-Pop effect. The more consistent the spatial location of audiovisual stimuli are, the greater the Pip-and-Pop effect will be. The more consistent the temporal audiovisual stimuli are, the greater the Pip-and-Pop effect will be.
