Results remain mixed regarding the effects of incubation tasks on divergent thinking, a type of creativity, generally assessed via the Unusual Uses Task (UUT). Using a within-subjects design, we compared 64 participants’ performance on the UUT, after four different incubation tasks: copy a simple painting, copy a complex painting, 0-back-task, and rest. We hypothesized that an arts-related activity during incubation (here: copy a painting) would boost subsequent creativity. Five different creativity scores were computed from the raw UUT data, and we provide a step-by-step guide for how to compute these: fluency, flexibility, originality, subjective creativity, and usefulness. Creativity was only modulated by sex; women outperformed men on creative fluency. No other variables, nor the incubations, modulated any of participants’ creativity scores. A within-group comparison showed that the unusual uses of our all-Iranian participants were more useful than unique, echoing previous work suggesting differences between Eastern and Western conceptions of creativity.

性别和文化对创造力的一些影响，孵化没有影响

关于孵化任务对发散思维（一种创造力）的影响，结果仍然好坏参半，通常通过不寻常用途任务（UUT）进行评估。使用受试者内设计，我们比较了 64 名参与者在 UUT 上的表现，这些参与者在完成四种不同的孵化任务后：复制简单的绘画、复制复杂的绘画、0-back-task 和休息。我们假设孵化期间与艺术相关的活动（此处：临摹一幅画）将提高随后的创造力。根据原始 UUT 数据计算出五种不同的创造力得分，我们提供了如何计算这些得分的分步指南：流畅性、灵活性、原创性、主观创造力和有用性。创造力只受性别的调节；女性在创意流畅性方面优于男性。没有其他变量，也没有孵化，调节任何参与者的创造力得分。组内比较表明，我们全伊朗参与者的不寻常用途比独特更有用，这与之前的研究相呼应，表明东西方创造力概念之间存在差异。
