我们的视觉系统将具有相似特征的空间上不同的区域组织成感知群。为了更好地理解分组的潜在机制,一种途径是研究其容量和时间进程。从直觉上看,这种能力似乎是无限的,而且这种时间进程感觉是即时的。相反,我们在这里表明,在需要相似性分组的视觉搜索任务中,搜索性能与这些组的连续处理是一致的。这在几个实验中都是正确的,对于在分组的对中寻找单个未分组的对,反之亦然,以及对于在分组的项目之间具有微小间隔的显示。在排除了显示复杂性混淆的控制条件下,当移除较小的对象间间隔以便接触对时,消除了按相似性分组的需要,搜索变得并行。为什么相似分组的发展如此缓慢?我们认为相似性分组就是“仅仅”特征选择--看到红色、明亮或正方形的分组是这些特征的全局选择。该帐户预测了一次一个特征组的连续处理,并对基于特征的选择的属性应该如何反映在相似性分组中做出了新的可证伪预测。
Our visual system organizes spatially distinct areas with similar features into perceptual groups. To better understand the underlying mechanism of grouping, one route is to study its capacity and temporal progression. Intuitively, that capacity seems unlimited, and the temporal progression feels immediate. In contrast, here we show that in a visual search task that requires similarity grouping, search performance is consistent with serial processing of those groups. This was true across several experiments, for seeking a single ungrouped pair among grouped pairs, vice versa, and for displays with tiny spacings between the grouped items. In a control condition that ruled out display complexity confounds, when the small inter-object spacing was removed so that that pairs touched, removing the need to group by similarity, search became parallel. Why is similarity grouping so slow to develop? We argue that similarity grouping is 'just' feature selection - seeing a red, bright, or square groupisglobal selection of those features. This account predicts serial processing of one feature group at a time, and makes new falsifiable predictions about how properties of feature-based selection should be reflected in similarity grouping.
