Causal Status and Coherence in Causal-Based Categorization
Rehder, Bob; Kim, ShinWoo
Journal of Experimental Psychology: Learning, Memory, and Cognition, v36 n5 p1171-1206 Sep 2010
Research has documented two effects of interfeature causal knowledge on classification. A "causal status effect" occurs when features that are causes are more important to category membership than their effects. A "coherence effect" occurs when combinations of features that are consistent with causal laws provide additional evidence of category membership. In this study, we found that stronger causal relations led to a weaker causal status effect and a stronger coherence effect (Experiment 1), that weaker alternative causes led to stronger causal status and coherence effects (Experiment 2), and that "essentialized" categories led to a stronger causal status effect (Experiment 3), albeit only for probabilistic causal links (Experiment 4). In addition, the causal status effect was mediated by features' subjective "category validity", the probability they occur in category members. These findings were consistent with a generative model of categorization but inconsistent with an alternative model. (Contains 10 tables, 23 figures and 6 footnotes.)
