Statistical summary representations (SSRs) are thought to be computed by the visual system to provide a rapid summary of the properties of sets of similar objects. Recently, it has been suggested that a change in the statistical properties of a set can be identified even when changes to the individual items comprising the set cannot. Haberman and Whitney (2011) showed that subjects were correctly able to report which of 2 consecutively presented sets of faces was, on average, happier, even when participants were unable to localize any of the items contributing to this change. In this article, we revisit this conclusion and suggest that the results supporting it may be an artifact of the paradigm used. In 4 experiments, we find little evidence to suggest that subjects can reliably detect a change in the average size or emotion of an array of faces when they are unable to localize changes to individual items. The results are well accounted for by assuming that observers are selectively attending to individual items and then inferring the direction of the overall change based on the behavior of the attended items. We suggest that this occurs because change localization requires focused attention to individual items, impeding calculation of SSRs, which requires global attention to the entire set. We conclude that there is currently little evidence that SSRs can facilitate change detection when individual change localization fails. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

变更本地化失败时变更检测能否成功?

统计摘要表示 (SSR) 被认为是由视觉系统计算的,以提供一组相似对象的属性的快速摘要。最近,有人建议即使当组成集合的单个项目的更改无法识别时,也可以识别集合的统计属性的更改。Haberman 和 Whitney (2011) 表明,即使参与者无法定位导致这种变化的任何项目,受试者也能够正确地报告连续呈现的 2 组面孔中的哪一组平均而言更快乐。在本文中,我们重新审视了这个结论,并建议支持它的结果可能是所使用范式的产物。在 4 个实验中,我们发现几乎没有证据表明,当受试者无法定位单个项目的变化时,他们可以可靠地检测到一组面孔的平均大小或情绪的变化。通过假设观察者有选择地关注单个项目,然后根据参与项目的行为推断整体变化的方向,可以很好地解释结果。我们建议发生这种情况是因为更改本地化需要将注意力集中在单个项目上,阻碍了 SSR 的计算,这需要对整个集合进行全局关注。我们得出的结论是,目前几乎没有证据表明当单个变更本地化失败时,SSR 可以促进变更检测。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。通过假设观察者有选择地关注单个项目,然后根据参与项目的行为推断整体变化的方向,可以很好地解释结果。我们建议发生这种情况是因为更改本地化需要将注意力集中在单个项目上,阻碍了 SSR 的计算,这需要对整个集合进行全局关注。我们得出的结论是,目前几乎没有证据表明当单个变更本地化失败时,SSR 可以促进变更检测。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。通过假设观察者有选择地关注单个项目,然后根据参与项目的行为推断整体变化的方向,可以很好地解释结果。我们建议发生这种情况是因为更改本地化需要将注意力集中在单个项目上,阻碍了 SSR 的计算,这需要对整个集合进行全局关注。我们得出的结论是,目前几乎没有证据表明当单个变更本地化失败时,SSR 可以促进变更检测。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。我们建议发生这种情况是因为更改本地化需要将注意力集中在单个项目上,阻碍了 SSR 的计算,这需要对整个集合进行全局关注。我们得出的结论是,目前几乎没有证据表明当单个变更本地化失败时,SSR 可以促进变更检测。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。我们建议发生这种情况是因为更改本地化需要将注意力集中在单个项目上,阻碍了 SSR 的计算,这需要对整个集合进行全局关注。我们得出的结论是,目前几乎没有证据表明 SSR 可以在单个变更本地化失败时促进变更检测。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。
