People can report summary statistics for various features about a group of objects. One theory is that different abilities support ensemble judgments about low-level features like color versus high-level features like identity. Existing research mostly evaluates such claims based on evidence of correlations within and between feature domains. However, correlations between two identical tasks that only differ in the type of feature that is used can be inflated by method variance. Another concern is that conclusions about high-level features are mostly based on faces. We used latent variable methods on data from 237 participants to investigate the abilities supporting low-level and high-level feature ensemble judgments. Ensemble judgment was measured with six distinct tests, each requiring judgments for a distinct low-level or high-level feature, using different task requirements. We also controlled for other general visual abilities when examining how low-level and high-level ensemble abilities relate to each other. Confirmatory factor analyses showed a perfect correlation between the two factors, suggesting a single ability. There was a unique relationship between these two factors beyond the influence of object recognition and perceptual speed. Additional results from 117 of the same participants also ruled out the role of working memory. This study provides strong evidence of a general ensemble judgment ability across a wide range of features at the latent level and characterizes its relationship to other visual abilities.

判断简单和复杂整体的一般能力。


人们可以报告一组对象的各种特征的汇总统计数据。一种理论认为，不同的能力支持对颜色等低级特征与身份等高级特征的整体判断。现有的研究主要根据特征域内部和特征域之间的相关性证据来评估此类主张。然而，仅使用的特征类型不同的两个相同任务之间的相关性可能会因方法方差而夸大。另一个担忧是，关于高级特征的结论大多基于人脸。我们对 237 名参与者的数据使用潜变量方法来研究支持低级和高级特征集成判断的能力。整体判断通过六个不同的测试来衡量，每个测试都需要使用不同的任务要求对不同的低级或高级特征进行判断。在检查低级和高级整体能力如何相互关联时，我们还控制了其他一般视觉能力。验证性因素分析显示这两个因素之间存在完美的相关性，表明具有单一能力。除了物体识别和感知速度的影响之外，这两个因素之间存在着独特的关系。 117 名相同参与者的额外结果也排除了工作记忆的作用。这项研究提供了强有力的证据，证明了潜在水平上广泛特征的一般整体判断能力，并描述了其与其他视觉能力的关系。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
