| Using an experiment with 77 academic professional participants, this dissertation examined the effects of positive mood and positive affectivity on creativity, together with the contexts of task hedonic tone and time. The results revealed that high positive mood and a pleasant task tone were related to higher creative performance. Moreover, a pleasant task tone had a stronger effect on creativity at the beginning period of the task than it did at the later periods. However, positive affectivity and the interactions of positive mood and positive affectivity with task hedonic tone showed insignificant effects on creativity over task periods. Theoretical and practical implications of the results are discussed. |
