The effect of arbitrary stimulus selection is a persistent concern when employing implicit measures. The current study tests a data-driven multi-step procedure to create stimulus items using a combination of free-recall and survey data. Six sets of stimulus items were created, representing healthy food and high sugar items in children, adolescents, and adults. Selected items were highly representative of the target concepts, in frequent use, and of near equal length. Tests of the piloted items in two samples showed slightly higher implicit measure-behavior relations compared to a previously used measure, providing preliminary support for the value in empirically based stimulus selection. Further, the items reported as being the most associated with their target concepts differed notably from what one may expect from the guidelines or population consumption patterns, highlighting the importance of informed stimulus selection.
在采用内隐测量方法时，任意刺激选择的影响一直是个令人担忧的问题。本研究测试了一种数据驱动的多步骤程序，该程序使用自由回忆和调查数据相结合的方式来创建刺激项目。创建了六组刺激项目，分别代表儿童、青少年和成年人的健康食品和高糖食品。所选项目高度代表目标概念，使用频率高，且长度相近。在两个样本中对试点项目进行的测试表明，与之前使用的测量方法相比，内隐测量与行为之间的关系略高，这为基于实证的刺激选择的价值提供了初步支持。此外，报告显示与目标概念最相关的项目与人们根据指导方针或总体消费模式所预期的项目有显著差异，这凸显了明智的刺激选择的重要性。
