Two free classification experiments that investigate the persistence of sort strategy are reported. Participants tend to persist with their initial categorization type (family resemblance or unidimensional) for the remaining sorts, overriding the effects of otherwise influential stimulus properties. Sort type was found to persist even after a one-week delay. Stimulus-driven models of free classification (e.g., the SUSTAIN model, [Love, B. C., Medin, D. L., & Gureckis, T. M. (2004). SUSTAIN: A network model of category learning. Psychological Review, 111, 309-332]) cannot predict the sort type persistence effects we observe, but they are naturally accounted for by theories that posit strategic selection of a problem-solving strategy (e.g., Hypothesis theory, [Levine, M. (1971). Hypothesis theory and nonlearning despite ideal S-R-reinforcement contingencies. Psychological Review, 78, 130-140]).
本文报告了两项关于探究分类策略持续性的自由分类实验。参与者倾向于在后续分类中坚持其最初的分类类型（家族相似性或单维性），而忽略其他具有影响力的刺激属性的影响。即使经过一周的延迟，分类类型仍被发现具有持续性。自由分类的刺激驱动模型（例如，SUSTAIN模型，[洛夫，B.C.，梅丁，D.L.，&古雷基斯，T.M.（2004年）。SUSTAIN：一种类别学习的网络模型。《心理评论》，111，309 - 332]）无法预测我们观察到的分类类型持续性效应，但这些效应可以由假设解决问题策略的战略选择的理论（例如，假设理论，[莱文，M.（1971年）。假设理论与尽管有理想的S - R强化条件但仍未学习。《心理评论》，78，130 - 140]）自然地解释。
