The Vanderbilt Holistic Face Processing Test (VHPT-F) is a new measure of holistic face processing with better psychometric properties relative to prior measures developed for group studies (Richler et al., 2014). In fields where psychologists study individual differences, validation studies are commonplace and the concurrent validity of a new measure is established by comparing it to an older measure with established validity. We follow this approach and test whether the VHPT-F measures the same construct as the composite task, which is group-based measure at the center of the large literature on holistic face processing. In Experiment 1, we found a significant correlation between holistic processing measured in the VHPT-F and the composite task. Although this correlation was small, it was comparable to the correlation between holistic processing measured in the composite task with the same faces, but different target parts (top or bottom), which represents a reasonable upper limit for correlations between the composite task and another measure of holistic processing. These results confirm the validity of the VHPT-F by demonstrating shared variance with another measure of holistic processing based on the same operational definition. These results were replicated in Experiment 2, but only when the demographic profile of our sample matched that of Experiment 1.
范德比尔特整体面部加工测试（VHPT-F）是一种新的整体面部加工测量方法，相对于之前为群体研究开发的测量方法，它具有更好的心理测量特性（Richler等人，2014年）。在心理学家研究个体差异的领域，验证研究很常见，新测量方法的同时效度是通过将其与具有既定效度的旧测量方法进行比较来确定的。我们采用这种方法，测试VHPT-F是否与复合任务测量相同的结构，复合任务是关于整体面部加工的大量文献核心的基于群体的测量方法。在实验1中，我们发现VHPT-F中测量的整体加工与复合任务之间存在显著相关性。虽然这种相关性较小，但它与在复合任务中对相同面孔但不同目标部分（顶部或底部）测量的整体加工之间的相关性相当，这代表了复合任务与另一种整体加工测量方法之间相关性的合理上限。这些结果通过证明与基于相同操作定义的另一种整体加工测量方法存在共同方差，证实了VHPT-F的效度。这些结果在实验2中得到了重复，但只有当我们样本的人口统计学特征与实验1相匹配时才成立。
