CommentA meta-analysis with nothing to hide: reply to Hyman (2010).
In our article (Storm, Tressoldi, & Di Risio, 2010), we claimed that the ganzfeld experimental design has proved to be consistent and reliable. However, Hyman (2010) argues that the overall evidence for psi is, in fact, contradictory and elusive. We present a case for psi research that undermines Hyman's argument. ⋯ Third, we argue that our meta-analysis has followed standard procedures, that we have not broken any rules but have found a communications anomaly, often referred to as psi. Though we may be in agreement that the evidence is largely statistical, the evidence suggests that concealed targets are actually identified rather than guessed. We argue that further research is necessary.

Meta AnalysisA meta-analytic review of achievement goal measures: different labels for the same constructs or different constructs with similar labels?
This meta-analysis addresses whether achievement goal researchers are using different labels for the same constructs or putting the same labels on different constructs. We systematically examined whether conceptual and methodological differences in the measurement of achievement goals moderated achievement goal intercorrelations and relationships with outcomes. We reviewed 243 correlational studies of self-reported achievement goals comprising a total of 91,087 participants. ⋯ Mastery-approach goal scales that contained goal-relevant language were not significantly related to performance outcomes (r = .05), whereas those that did not contain goal-relevant language had a positive relationship with performance outcomes (r = .14). We concluded that achievement goal researchers are using the same label for conceptually different constructs. This discrepancy between conceptual and operational definitions and the absence of goal-relevant language in achievement goal measures may be preventing productive theory testing, research synthesis, and practical application.

Meta AnalysisA meta-analysis of the five-factor model of personality and academic performance.
This article reports a meta-analysis of personality-academic performance relationships, based on the 5-factor model, in which cumulative sample sizes ranged to over 70,000. Most analyzed studies came from the tertiary level of education, but there were similar aggregate samples from secondary and tertiary education. There was a comparatively smaller sample derived from studies at the primary level. ⋯ Strong evidence was found for moderators of correlations. Academic level (primary, secondary, or tertiary), average age of participant, and the interaction between academic level and age significantly moderated correlations with academic performance. Possible explanations for these moderator effects are discussed, and recommendations for future research are provided.

ReviewReligion, self-regulation, and self-control: Associations, explanations, and implications.
Many of the links of religiousness with health, well-being, and social behavior may be due to religion's influences on self-control or self-regulation. Using Carver and Scheier's (1998) theory of self-regulation as a framework for organizing the empirical research, the authors review evidence relevant to 6 propositions: (a) that religion can promote self-control; (b) that religion influences how goals are selected, pursued, and organized; (c) that religion facilitates self-monitoring; (d) that religion fosters the development of self-regulatory strength; (e) that religion prescribes and fosters proficiency in a suite of self-regulatory behaviors; and (f) that some of religion's influences on health, well-being, and social behavior may result from religion's influences on self-control and self-regulation. The authors conclude with suggestions for future research.
