RESUMO
We conducted a preregistered multilaboratory project (k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result (d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect (d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.

This article suggests that undergraduate research can help advance the science of psychology. We introduce a hypothetical "question-list paradigm" as a mechanism to do this. Each year, thousands of undergraduate projects are completed as part of the educational experience. Although many of these studies may not contain sufficient contributions for publication, they provide a good test of the replicability of established findings across populations at different institutions and geographic locations. Thus, these projects could meet the needs of recent calls for increased replications of psychological studies while simultaneously benefiting the student researchers, their instructors, and the field in general.
RESUMO
The assumption that implicit measures assess associations that are not accessible to consciousness abounds in current social cognition research. In the present report, we question this assumption, focusing on the construct of implicit self-esteem as a case in point. Although researchers often argue that implicitly measured self-esteem is unconscious, we provide evidence that it is not, and that discrepancies between implicit and explicit measures of self-esteem are the result of reporting tendencies. Study 1 demonstrated that individuals for whom explicitly measured self-esteem is relatively high and implicitly measured self-esteem is relatively low admit to overpresenting themselves. In Study 2, implicit and explicit measures of self-esteem were related when subjects were urged to avoid over- or underpresenting themselves when responding to the explicit measures. We discuss the critical distinction between awareness of one's attitudes and awareness of their influence.

A. E. Kelly's (2000) thesis that psychotherapy clients benefit from withholding negative information is considered in light of current social-psychological theory and research. Positive illusions about oneself are associated with indexes of mental health; this is consistent with treating therapy as positive identity development. Self-presentation can shape self-concept, even apart from the feedback that an audience might provide; the social construction of identity is a powerful process, suggesting that withholding negative and presenting only positive information is adaptive. However, evidence concerning the level of identification of one's actions suggests complexities in understanding ways clients might deal with disclosing negative information; the authors argue that the impact on self-concept is probably more complex than A. E. Kelly's characterization and that the implications are of a broader scope than indicated so far.
