【 摘 要 】

Distribution analyses are becoming increasingly popular in the psychological literature as they promise invaluable information about hidden cognitive processes (e.g., Ratcliff and Rouder, 1998; Ratcliff et al., 1999; Wagenmakers et al., 2005; Miller, 2006; Freeman and Dale, 2013). One particular approach probes distributions for uni- vs. bi-modality, because bimodality often results from the contribution of dual processes underlying the observed data (Larkin, 1979; Freeman and Dale, 2013; see Knapp, 2007, for a historical overview). Although several statistical tools for this purpose exist, it remains unclear which one can be considered as a gold standard for assessing bimodality in practice.
