Mind wandering in creative problem-solving: Relationships with divergent thinking and mental health.

Previous research has shown that mind wandering has both positive and negative effects. Mind wandering may improve creative problem solving; however, it could also lead to negative moods and poor mental health. It has also been shown that some forms of mental illness are positively related to creativity. However, the three factors of mind wandering, divergent thinking, and mental health have not been examined simultaneously, so it is possible that these relationships are manifested by spurious correlations. Therefore, we examined the relations among the three factors while controlling for each of their confounding effects. We asked 865 participants (458 men, 390 women, 17 unknown; Mage = 18.99 years, SD = 1.16) to complete a questionnaire measuring mind wandering traits, divergent thinking, and mental health measures including depressive symptoms and schizotypal personality. Multiple regression analysis showed that people who reported more depressive symptoms, schizotypal personality, and divergent thinking, were more likely to engage in mind-wandering. Our results indicated that frequency of mind wandering was linked to a risk of poorer mental health as well as to higher divergent thinking ability. In future research, we will examine the features of mind wandering related to divergent thinking and mental health by considering the contents of wandering thoughts and whether they are ruminative or not. We also need to examine whether the same results will be found when studying professionals in creative occupations, and when using different scoring methods in divergent thinking tests.

Does Mind Wandering During the Thought Incubation Period Improve Creativity and Worsen Mood?

Enhancing creative problem-solving is increasingly important in a modern globalized society. Previous research has shown that creative problem-solving can be improved if the mind is allowed to wander during time set aside from solving a problem, known as the incubation period. However, some research also suggests that mind wandering leads to negative affect. Our study aims to clarify the effect of mind wandering during the incubation stage on both creative problem-solving and mood while controlling for the effect of working memory capacity. Fifty-two students (both undergraduate and graduates) completed a working memory task and repeated a creative problem-solving task at intervals before and after an incubation period. At the end of the incubation period, we measured participants' frequency of mind wandering and their moods. Results showed that the group with the higher frequency of mind wandering showed the most improvement in one indicator of creativity, flexibility, although this finding was not significant after adjusting for the other four facets. Moreover, our findings indicate that as creativity improved, more negative affect was generated. Our results suggest that mind wandering during the incubation stage could be used to generate more diverse ideas but also suggest that there is a risk attached. Further research should explore how specific features of mind wandering might improve creativity without generating negative affect.

[Mind-wandering enhances creative problem solving].

An "incubation period" refers to an individual's temporary shift away from an unsolved problem, which ultimately facilitates better problem solving. In this study, we experimentally examined whether creative problem solving was facilitated in accordance with the frequency of mind-wandering during an incubation period. Fifty-nine Japanese undergraduate participants (23 men and 36 women) were asked to complete the Unusual Uses Test (UUT) twice; the UUT is a traditional measurement of the various aspects of divergent thinking (including fluency, flexibility, and originality). They were also asked to rate the frequency in which they engaged in mind-wandering during the interval between UUTs, which was considered as the incubation period. The results indicated that participants who reported a higher frequency of mind-wandering during incubation exhibited more creative solutions on the UUT, especially in terms of flexibility and originality, than did those reporting a lower frequency of mind-wandering.
