先前的证据表明，学龄前儿童和小学生在概率环境中做出决策时，在很大程度上没有系统的计划。然而，这一发现可能是由于标准分类方法的不敏感性，该方法假设同类任务的决策策略缺乏方差。使用一种新的方法，我们探索了现有数据中的策略变异性，这些数据记录了儿童的非系统性搜索（Betsch，Lehmann，Lindow，Lang和Schoemann，2016）。通过发音和可视化，我们确定了儿童系统使用的搜索模式的组合。与成人对照组相比，儿童没有支配策略。相反，他们使用了有限数量的策略（工具箱），并在属于同一类型决策任务的一系列试验中在它们之间切换。
Prior evidence has suggested that preschoolers and elementary schoolers search information largely with no systematic plan when making decisions in probabilistic environments. However, this finding might be due to the insensitivity of standard classification methods that assume a lack of variance in decision strategies for tasks of the same kind. Using a novel approach, we explore strategy variability in existing data that documented unsystematic searches in children (Betsch, Lehmann, Lindow, Lang, & Schoemann, 2016). By means of sonification and visualizations, we identified combinations of search patterns that children employed systematically. In contrast to adult controls, there was no dominating strategy in children. Rather, they used a limited number of strategies (toolboxes) and switched between them over a series of trials belonging to the same type of decision task.
