根据视觉注意力的基于对象的理论，注意力可以在单个对象内比在单独的对象之间更有效地划分（J.邓肯，1984）。最近，GC Baylis和J.Driver（1993）在空间组织领域内提供了一个解释这种单目标优势的理论框架。使用他们对位置假设的分层编码，他们发现，对于被视为单个（凸）对象的一部分的顶点，比较2个顶点位置的延迟明显快于被视为单独（凹）对象的一部分的顶点。这篇文章报道了这一发现的重复，以及新的证据表明，延迟是由轮廓的凸性，而不是由对象的数量。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
According to object-based theories of visual attention, attention can be divided within a single object more efficiently than between separate objects (J. Duncan, 1984). Recently, GC Baylis and J. Driver (1993) provided a theoretical framework for interpreting this single-object advantage within the domain of spatial organization. Using their hierarchical coding of location hypothesis, they showed that the latency to compare the location of 2 vertices was significantly faster for vertices that were seen as parts of a single (convex) object than for vertices that were seen as parts of separate (concave) objects. This article reports the replication of this finding, as well as new evidence that shows that latency is affected by the convexity of the contour, and not by the number of objects.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
