- Cognition plays a key role in sports performance. This meta-analytic review synthesizes research that examined the relationship between cognitive functions, skills, and sports performance. We identified literature by searching Cochrane Library, APA PsycINFO, PubMed, and Web of Science. We included studies conducted on competitive athletes, assessed cognitive prerequisites, and included performance measures related to the sport. Of the 9,433 screened records, 136 reports were included, containing 142 studies, 1,227 effect sizes, and 8,860 participants. Only 11 studies used a prospective study design. The risk of bias was assessed using the Risk of Bias Assessment Tool for Nonrandomized Studies. The multilevel meta-analysis showed a medium effect size for the overall difference in cognitive functions and skills, with higher skilled athletes scoring better than lower skilled athletes (Hedges' g = 0.59, 95% CI [0.49, 0.69]). The moderator analysis showed larger effect size for tests of cognitive decision-making skills (g = 0.77, 95% CI [0.6, 0.94]) compared to basic (g = 0.39, 95% CI [0.21, 0.56]) and higher cognitive functions (g = 0.44, 95% CI [0.26, 0.62]), as well as larger effect for sport-specific task stimuli compared to general ones. We report that higher skilled athletes perform better on cognitive function tests than lower skilled athletes. There was insufficient evidence to determine whether cognitive functions and skills can predict future sport performance. We found no evidence to support claims that tests of general cognitive functions, such as executive functioning, should be used by practitioners for talent identification or player selection. Public Significance Statement This meta-analysis indicates that testing cognitive functions or skills using sport-specific stimuli has the potential to differentiate between elite and nonelite athletes. There is, however, no evidence for the usefulness of using general, non-sport-specific cognitive function tests to predict future sport performance.

Journal article (peer-reviewed)abstract
- Knowledge sharing involves the provision or receipt of information, know-how, best practices, lessons learned, and/or feedback about a task, product, and/or procedure in order to develop new skills and competencies at work which can improve individual, group, and/or organizational performances. Based on self-determination theory, the study partners hypothesized that people with more self-determined latent profiles will report more knowledge sharing at work over 18 months than people with less self-determined latent profiles. Participants were 299 dental hygienists who completed a national online survey at baseline and at 18 months. Results of a Latent Profile Analysis revealed that dental hygienists with the most self-determined profile (Profile 2) reported a higher level of knowledge sharing at work at 18 months than dental hygienists in: Profile 1, "the controlled profile, " characterized by perceptions of managerial control and relatively high levels of the control orientation - moderate effect size; Profile 3, "the helpless profile, " characterized by the impersonal orientation and an absence of the autonomy orientation - large effect size; and Profile 4, "the mixed profile, " characterized by both the highest levels of fear of failure and control orientation but also by high levels of autonomy orientation and perceived managerial autonomy support - moderate effect size. Applied implications, particularly around ways to maximize managerial autonomy support and minimize managerial control to promote well-being and performance and reduce ill-being and non-effective functioning, are discussed. © 2021 By Author(s).
