Investigating interactions between types of order in categorization

Abstract : This study investigates how different types of presentation orders influence category learning and generalization. We used a full factorial design (within-category, between-category, and across-blocks manipulations), each factor having two levels (rule-based vs. similarity-based, blocked vs. interleaved, and constant vs. variable orders, respectively). This research offers a unique and novel approach through both an individual and concurrent analysis of the studied factors. Moreover, the investigation of across-blocks manipulations is unprecedented. Using survival analysis techniques as well as non-parametric tests, we found that learning was impacted by both within-category and across-blocks manipulations (with across-blocks manipulation being the main predictor). More specifically, the rule-based and constant orders were found more beneficial than the similarity-based and variable orders, respectively. Also, within-category and between-category orders were found to affect generalization patterns. More precisely, participants in the rule-based order more often showed generalization patterns consistent with a rule-based strategy than participants in the similarity-based order. Likewise, participants in the interleaved order more often showed generalization patterns consistent with a rule-based strategy than participants in the blocked order. We conclude that combining a similarity-based order with a variable across-blocks manipulation delays learning, whereas combining a rule-based order with a constant across-blocks manipulation benefits learning. Furthermore, combining a rule-based order with an interleaved order favors the use of a rule-based strategy during category generalization.
