Mind-Body Practices and Self-Enhancement: Direct Replications of Gebauer et al.'s (2018) Experiments 1 and 2

Abstract

Mind-body practices such as yoga and meditation are often believed to instill a "quiet ego," entailing less self-enhancement. In two experiments, however, Gebauer et al. (2018) demonstrated that mind-body practices may actually increase self-enhancement, particularly because such practices become self-central bases for self-esteem. We conducted preregistered replications of both of Gebauer et al.'s experiments. Experiment 1 was a field study of Canadian yoga students (N = 97), and Experiment 2 was a multiwave meditation intervention among Canadian university students (N = 300). Our results supported Gebauer et al.'s original conclusions that mind-body practices increase self-enhancement. Although the self-centrality effects were not clearly replicated in either experiment, we found evidence that measurement and sampling differences may explain this discrepancy. Moreover, an integrative data analysis of the original and the replication data strongly supported all of Gebauer et al.'s conclusions. In short, we provide new evidence against the ego-quieting perspective and in support of the self-centrality interpretation of mind-body practices.
