A sequential design characterized by a mixture of a cross-sectional and a nine-month follow-up longitudinal design was used to allow both between and within groups comparisons. Two schools using the "through-train mode" for school promotion were invited to participate in order to ensure that follow-up measures could be made. A total of 405 schoolchildren (213 boys, 192 girls) completed the study, with 144 in the G5-6 group (i.e., grade promotion from Grade 5 to Grade 6), 142 in the G6-7 group (i.e., school transition from Grade 6 to Grade 7), and 119 in the G7-8 group (i.e., grade promotion from Grade 7 to Grade 8). The creative thinking, stress levels, and conventionality in thinking of the participants were measured using three parallel forms of the Test for Creative Thinking-Drawing Production (TCT-DP), Stress Appraisal Measures (SAM), and the Conventionality Test at 3 time-points (i.e., before, during, and after promotion to a new school or higher grade)., In the fast-changing modern world, creativity has become increasingly important for dealing with complex problems and opportunities. Improving creativity is therefore important for both individuals and societies. Studying creativity development can help us to infer the contributing factors that may hinder or enhance creativity. Studies on creativity development during childhood and adolescence have suggested that a creativity slump is a special, but common, phenomenon. Yet it remains unclear why a creativity slump occurs at a specific age or at a specific time of development. The present dissertation provides a direct empirical comparison of two competing hypotheses on the creativity slump. The school transition stress hypothesis, drawn from the continuity or experience perspective of human development, suggests that a creativity slump is related to the stress associated with school transition, whereas the cognitive-developmental hypothesis, which takes the stage perspective of human development, suggests that the conventional thinking stage inhibits the expression of creativity and is hence conducive to a slump. The explanatory power of these two theoretical perspectives in relation to a creativity slump was tested by addressing the research question as to whether a creativity slump would still occur if school transition occurred at the cognitive stage that is beyond the conventional thinking stage (i.e., the postconventional thinking stage). The study explicitly compared the relative contribution of stress appraisal and conventionality in thinking to creativity development., In the present study, it was found that a creativity slump still occurred when school transition took place during the postconventional thinking stage, lending support to the school transition stress hypothesis, but not to the cognitive-developmental hypothesis, regarding a creativity slump at school transition. We further clarified the specific roles of cognitive appraisals of stress in relation to creativity. Negative stress appraisals (i.e., appraising school life as threatening) were negatively predictive of creativity, whereas positive stress appraisals (i.e., appraising school life as challenging and controllable) were positively predictive of creativity. Regarding the role of level of conventionality in thinking in creativity, the results suggest that although postconventional thinking has a positive effect on creative thinking, its effect on creative thinking is significantly mediated by stress appraisals. The results also showed individual differences in experiencing a creativity slump. The statistic that only 44.4% of the students in the school transition group experienced a slump lends support to the idea that a creativity slump is neither overwhelming nor unavoidable. In accounting for these individual differences, stress appraisal variables were found to be the significant predictors when both the stress appraisal and conventionality in thinking variables were included in the logistic regression equation to predict the occurrence of a slump., The present dissertation contributes to the current literature by offering empirical evidence to address the explanatory power of the cognitive-relational theory of stress and the cognitive-developmental perspective in relation to the existence of a creativity slump. The findings suggest that the major factors that are detrimental to creative thinking at school transition are negative appraisals and lack of positive appraisals on school life (i.e., viewing school life as more threatening, less challenging, and less controllable). These findings are helpful for understanding the critical factors that either facilitate or hinder the development of creativity in schoolchildren, which, in turn, could shed further light on effective creativity education., He Wu, Jing., Adviser: Wan Chi Wong., Source: Dissertation Abstracts International, Volume: 73-03, Section: B, page: ., Thesis (Ph.D.)--Chinese University of Hong Kong, 2010., Includes bibliographical references (leaves 125-138)., Electronic reproduction.
