Performance in rapid serial visual presentation tasks has been shown to depend on the temporal integration of target stimuli when they are presented in direct succession. Temporal target integration produces a single, combined representation of visually compatible stimuli, which is comparatively easy to identify. It is currently unknown to what extent target compatibility affects this perceptual behavior, because it has not been studied systematically to date. In the present study, the effects of compatibility on temporal integration and attention were investigated by manipulating the Gestalt properties of target features. Of particular interest were configurations in which a global illusory shape was formed when all stimulus features were present; a Kanizsa stimulus, which was expected to have a unifying effect on the perception of the successive targets. The results showed that although the presence of a Kanizsa shape can indeed enhance temporal integration, this also was observed for other good Gestalts, such as due to common fate and closure. Identification accuracy seemed to vary, possibly as a result of masking strength, but this did not seem associated with attentional processing per se. Implications for theories of Gestalt processing and temporal integration are discussed.
研究表明，当目标刺激相继直接呈现时，快速序列视觉呈现任务的表现取决于目标刺激的时间整合。时间目标整合会产生一个视觉上兼容刺激的单一、组合表征，相对容易识别。目前尚不清楚目标兼容性在多大程度上影响这种感知行为，因为迄今为止尚未对此进行系统研究。在本研究中，通过操纵目标特征的格式塔属性，研究了兼容性对时间整合和注意力的影响。特别令人感兴趣的是当所有刺激特征都存在时形成全局错觉形状的构型；一种卡尼萨刺激，预计它会对连续目标的感知产生统一作用。结果表明，虽然卡尼萨形状的存在确实可以增强时间整合，但其他良好的格式塔，如由于共同命运和封闭性，也观察到了这种情况。识别准确性似乎有所不同，可能是由于掩蔽强度，但这似乎与注意力加工本身无关。讨论了对格式塔加工和时间整合理论的启示。
