Visual perception involves binding of distinct features into a unified percept. Although traditional theories link feature binding to time-consuming recurrent processes, Holcombe and Cavanagh (2001) demonstrated ultrafast, early binding of features that belong to the same object. The task required binding of orientation and luminance within an exceptionally short presentation time. However, because visual stimuli were presented over multiple presentation cycles, their findings can alternatively be explained by temporal integration over the extended stimulus sequence. Here, we conducted three experiments manipulating the number of presentation cycles. If early binding occurs, one extremely short cycle should be sufficient for feature integration. Conversely, late binding theories predict that successful binding requires substantial time and improves with additional presentation cycles. Our findings indicate that task-relevant binding of features from the same object occurs slowly, supporting late binding theories.
视觉感知涉及将不同的特征绑定到一个统一的感知中。尽管传统理论将特征绑定与耗时的递归过程联系在一起，但霍洛姆和卡瓦纳（2001 年）证明了属于同一物体的特征可以超快、早期绑定。该任务要求在极短的呈现时间内绑定方向和亮度。然而，由于视觉刺激在多个呈现周期中呈现，他们的发现也可以通过在扩展的刺激序列上进行时间整合来解释。在这里，我们通过操纵呈现周期的数量来进行三个实验。如果早期绑定发生，则一个极短的周期应该足以进行特征整合。相反，后期绑定理论预测成功的绑定需要大量的时间，并且随着呈现周期的增加而提高。我们的研究结果表明，来自同一物体的特征的任务相关绑定发生得很慢，支持后期绑定理论。
