This article describes a research program exploring the structure, correlates, and consequences of creative mindsets, defined as beliefs about the fixed-versus-growth nature of creativity. In the first study, I reported on the development of the Creative Mindset Scale. Exploratory factor analysis demonstrated a two-factor structure with growth-and fixed-creative mindsets forming two relatively independent, yet negatively correlated scales, rather than two ends of one continuum. I then verified this structure by confirmatory factor analysis using a larger sample. In the second study, the growth mindset and the creative self-concept (creative self-efficacy and creative personal identity) were strongly positively associated. In the third study, the fixed-creative mindset was negatively related to efficiency in solving insight problems, and an association between the growth mindset and problem solving was moderated by the fixed mindset.

Background To limit the rapid spread of COVID‐19, countries have asked their citizens to stay at home. As a result, demographic and cultural factors related to home life have become especially relevant to predict population well‐being during isolation. This pre‐registered worldwide study analyses the relationship between the number of adults and children in a household, marital status, age, gender, education level, COVID‐19 severity, individualism–collectivism, and perceived stress. Methods We used the COVIDiSTRESS Global Survey data of 53,524 online participants from 26 countries and areas. The data were collected between 30 March and 6 April 2020. Results Higher levels of stress were associated with younger age, being a woman, lower level of education, being single, staying with more children, and living in a country or area with a more severe COVID‐19 situation. Conclusions The COVID‐19 pandemic revealed that certain people may be more susceptible to experience elevated levels of stress. Our findings highlight the need for public health to be attentive to both the physical and the psychological well‐being of these groups.

This article reports on a meta-analysis of 120 studies (total N = 52,578; 782 effects) examining the relationship between creativity and academic achievement in research conducted since the 1960s. Average correlation between creativity and academic achievement was r = .22, 95% CI [.19, .24]. An analysis of moderators revealed that this relationship was constant across time but stronger when creativity was measured using creativity tests compared to self-report measures and when academic achievement was measured using standardized tests rather than grade point average. Moreover, verbal tests of creativity yielded significantly stronger relationships with academic achievement than figural tests. Theoretical and practical consequences are discussed.

Although the view that women's olfactory abilities outperform men's is taken for granted, some studies involving large samples suggested that male and female olfactory abilities are actually similar. To address this discrepancy, we conducted a meta-analysis of existing studies on olfaction, targeting possible sex differences. The analyzed sample comprised n = 8 848 (5 065 women and 3 783 men) for olfactory threshold (as measured with the Sniffin Sticks Test; SST), n = 8 067 (4 496 women and 3 571 men) for discrimination (SST), n = 13 670 (7 501 women and 6 169 men) for identification (SST), and a total sample of n = 7 154 (3 866 women and 3 288 men) for works using University of Pennsylvania Smell Identification Test (UPSIT). We conducted separate meta-analyses for each aspect of olfaction: identification, discrimination and threshold. The results of our meta-analysis indicate that women generally outperform men in olfactory abilities. What is more, they do so in every aspect of olfaction analyzed in the current study. However, the effect sizes were weak and ranged between g = 0.08 and g = 0.30. We discuss our findings in the context of factors that potentially shape sex differences in olfaction. Nevertheless, although our findings seem to confirm the “common knowledge” on female olfactory superiority, it needs to be emphasized that the effect sizes we observed were notably small.

The aim of this study was to examine the relation of the Big Five personality factors to two self‐concept variables of growing importance in creativity literature: creative self‐efficacy (CSE) and creative personal identity (CPI). The analysis, conducted on a large (N = 2674, 49.6% women) and varied‐in‐age (15–59 years old) nationwide sample of Poles, using the structural equation model, demonstrated that personality factors are responsible for 23% of CSE and 21% of CPI variances. CSE and CPI were associated with all five personality dimensions: positively with Openness to Experience, Extraversion and Conscientiousness, negatively with Neuroticism and Agreeableness. The separate analyses conducted on men and women showed the differences among the predictors of CSE and CPI. Although Openness to Experience, Conscientiousness, and Neuroticism predicted CSE among both men and women, Extraversion was positively and Agreeableness negatively related to women's CSE. Conscientiousness was positively related to CPI only among men, and Agreeableness was negatively related to it only among women. Extraversion, Neuroticism, and Openness predicted CPI in the same manner among men and women.

The neural plasticity of the olfactory system offers possibilities of treatment in terms of stimulation of the sense of smell, and different studies have suggested effectiveness of smell training, i.e., daily exposition to certain odors. To obtain reliable and precise estimates of overall treatment benefit on the olfactory function, we meta-analyzed the effects of smell training reported in 13 previous studies. We analyzed the smell training effectiveness across three different olfactory abilities, smell identification, discrimination and threshold for odor detection. We found a significant, positive effect of olfactory training for all olfactory abilities, with large effects of training on identification, discrimination and TDI-score and small-to-moderate effect in the case of threshold for odor detection. Interestingly, the pattern of results differed across Sniffin Sticks subtests depending on the origin of participants smell disorder, and the smell training duration influenced its effectiveness in the case of identification and the TDI score. Although the exact mechanism of olfactory recovery following the smell training still requires further investigation, our meta-analysis showed that such training should be considered an addition or alternative to existing smell treatment methods.
