... Psychological determinism: These determinants impact the speed and accuracy of the player's information processing and emotional state during the game. This state can range from the intense excitement and focused attention of being "in flow" (Csikszentmihalyi, 1975(Csikszentmihalyi, , 2002Vrooman et al., 2022) to increased anxiety or apathy. Additionally, the mental desire of participation in competitive playing can be caused by unconscious escape determined by too high or very low levels of brain innervation as explained by the arousal motivation theory (Berlyne, 1960; see also Ellis, 1973). ...

... The usefulness of flow in rehabilitation has been explored in 514 multiple studies (Ottiger et al., 2021;Riva et al., 2016;Yoshida et al., 2018). However, 515 Tse et al. (2022) emphasized that flow experiences may not occur during deliberate 516 practice because the constant monitoring of one's own performance is incompatible 517 with the complete immersion and loss of self-consciousness required for flow. Recent 518 studies have underlined the situatedness and experience of natural materials that are part of the enjoyable experience, thus, focusing on being rather than becoming (Bentz et al., 520 2021;Fahy et al., 2021;von Kürthy et al., 2022). ...

... On the other hand, we have sometimes simplified the student interface based on feedback from classroom trials. We argue this simplification is appropriate, as it provides an accessible level of challenge to students who are apprenticing to new scientific practices (Nakamura & Csikszentmihalyi, 2014). ...

... Our findings are notable for two reasons. First, although the benefits of chosen (or self-determined) solitude are well-established (e.g., Lay et al., 2020;Tse et al., 2022), our research suggests that even unchosen solitude can deactivate intense emotions and promote affective regulation. Second, we show that even people struggling with high levels of loneliness-who generally view solitude as an aversive experience-can experience solitude more positively by altering the way they think about being alone. ...

... Csikszentmihalyi's suggested 547 connection between flow and well-being is now supported by neuroscience. For 548 example, Sadlo (2016) psychology (Kukita et al., 2022;Tse et al., 2021) and the studies included in this meta-554 study, highlight broader contextual issues of accessibility and participation. 555 ...

... According to Lynch and Troy (2021), both a short-term reduction in negative emotions and an increase in positive emotions are experienced following optimal psychological states. Furthermore, Tse, Nakamura, and Csikszentmihalyi (2021) found that people who experienced optimal psychological states on a regular basis were more likely to report higher overall well-being. In addition, flow states have been found to be a motivational factor for continuing to take part in tourism (Ewert et al., 2020;Zhou et al., 2019). ...

... learner's perceived skill level is important. Adding complexity to the task makes it more challenging, and at the same time causes a lower experienced skill level, which can subsequently lead to worry or anxiety (Nakamura et al., 2019). Therefore, we had to simplify our exercise: some of the information and discussion topics were removed so that the word count decreased by 30 percent; we restructured the remaining information more clearly; we made a new map for the Invicta base that was easier to use; and we provided extra tools that could help them, such as a budget calculation template. ...

... In the third hypothesis (H3), we observed that obsessive passion negatively relates to individual performance, which means that compulsively obsessing over something may affect individual performance. Obsession leads to distraction or time demands, impairing the ability to concentrate and accomplish tasks at work (Lucas et al., 2019;Choi et al., 2020;Pollack et al., 2020;Ho et al., 2021). The anxiety and stress resulting from obsession negatively affect the individual's mental and physical health, ergo impairing work performance (Damirchi et al., 2020;Manning et al., 2021;Serrano-Fernandez et al., 2021;Vismara et al., 2021). ...

... The study of the optimal psychological states is relevant for the relation of their characteristics and the best experiences in human beings. While clutch is still under study, flow state has been understood as the intersection between the greatest experiences and peak performance (Jackson and Roberts, 1992;Kimiecik and Stein, 1992;Jackson and Marsh, 1996;Engeser and Rheinberg, 2008;García Calvo et al., 2008;Bakker et al., 2011;Swann et al., 2012;Verner-Filion and Vallerand, 2018;Tse et al., 2019). In any case, flow experience has been considered rare and elusive (Csikszentmihalyi, 1975b(Csikszentmihalyi, , 1986Kimiecik and Stein, 1992;Swann et al., 2017a). ...

... Since the effects of physical activity engagement on positive affect might decay after 3 h (Wichers et al., 2012) and affect levels might change even faster (Santangelo et al., 2016), a 24-h recall might overlook or underestimate the shortterm stress-buffering dynamics. For an adequate capturing of these dynamics, the experience sampling methodology (ESM) is ideally suitable and allows to investigate stress buffering in closer proximity to the actual experiences (i.e. on several occasions within individuals' days; McLean et al., 2020). By increasing the resolution from a daily to a momentary level, ESM might thus help to capture the within-person stress-buffering dynamics more appropriately (Puterman et al., 2017). ...
