Most psychological studies rely on student samples. Students are usually considered as more homogenous than representative samples both within and across countries. However, little is known about the nature of the differences between student and representative samples. This is an important gap, also because knowledge about the degree of difference between student and representative samples may allow to infer from the former to the latter group. Across 59 countries and 12 personality (Big-5) and attitudinal variables we found that differences between students and general public were partly substantial, incoherent, and contradicted previous findings. Two often used cultural variables, embeddedness and intellectual autonomy, failed to explain the differences between both groups across countries. We further found that students vary as much as the general population both between and within countries. In summary, our results indicate that generalizing from students to the general public can be problematic when personal and attitudinal variables are used, as students vary mostly randomly from the general public. Findings are also discussed in terms of the replication crisis within psychology.

Little research has examined mean-level change in values across the life span. Using large cross-sectional data (N = 36,845) from the five geo-social regions in Brazil, this study examines how mean levels of basic values differ as a function of age (from age 12 to 65; M = 28) and whether age effects are moderated by gender. Results show that mean-level value change is substantial throughout the life course. We observed both linear and curvilinear patterns of change as well as differential patterns by gender. The observed value change is consistent with age-related life circumstances and psychosocial development. Age effects are also value dependent, supporting the notion that values have different functions for different developmental stages.

Digitalization of knowledge work is essential for today’s organizations, responding to diversified employee needs. Many organizations are already implementing some form of flexibility to help workers perform work and non-work duties, while maintaining high productivity. While these changes in workplaces, “New Ways of Working (NWW)”, have been discussed in the literature, a systematic appraisal of evidence of NWW has not been conducted. Relating to poor work-related mental health worldwide, this systematic review analyzed the psychological impacts of NWW, and the quality and quantity of NWW research. Following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines, NWW studies targeting psychological outcomes were evaluated. Initial literature search on ProQuest, PsycINFO, Science Direct, and Google Scholar retrieved 308 titles, from which seven articles fulfilled all inclusion criteria. Our appraisal revealed that NWW research evaluated diverse psychological outcomes. While NWW can help workers’ engagement, work-related flow, and connectivity among staff, NWW can also increase blurred work-home boundary, fatigue, and mental demands. The quality of NWW research was overall medium, needing more rigorous studies. Our findings can inform decision-makers in the workplace to effectively implement NWW, and researchers to improve the quality and the usefulness of future NWW studies.

The benefits of nature for our health have been an increasing research focus in recent years. In the context of a global increase in mental health diagnoses, the potential health benefits of nature have attracted attention. One practical nature treatment is to walk in nature. However, evidence for this practice on mental health has not been comprehensively appraised to date. This systematic review synthesized the effects of nature walks for depression and anxiety, and evaluated the methodological rigor of studies. Academic databases including ProQuest, PsycINFO, Science Direct, and Google Scholar were utilized to identify eligible articles, which were examined using the Newcastle–Ottawa Scale. Of 385 articles initially retrieved, 12 studies met all the eligibility criteria (nine pre-post within-subject studies, two quasi-experimental studies, and one experimental between-subjects study). These studies demonstrated that nature walks were effective for state anxiety but not generalized anxiety and the effects for depression were inconsistent. Findings indicate that nature walks may be effective for mental health, especially for reducing state anxiety. However, the quality of the included studies varied, and sample sizes were small, suggesting a need for more rigorous and large-scale research.

Previous research found that the within-country variability of human values (e.g., equality and helpfulness) clearly outweighs between-country variability. Across three countries (Brazil, India, and the United Kingdom), the present research tested in student samples whether between-nation differences reside more in the behaviors used to concretely instantiate (i.e., exemplify or understand) values than in their importance as abstract ideals. In Study 1 (N = 630), we found several meaningful between-country differences in the behaviors that were used to concretely instantiate values, alongside high within-country variability. In Study 2 (N = 677), we found that participants were able to match instantiations back to the values from which they were derived, even if the behavior instantiations were spontaneously produced only by participants from another country or were created by us. Together, these results support the hypothesis that people in different nations can differ in the behaviors that are seen as typical as instantiations of values, while holding similar ideas about the abstract meaning of the values and their importance.
