Acute Effects of Improvisational Dance and Choreography Learning on Cognitive Function and Creativity of Experienced Hip-hop Dancers

This study explored whether the different forms of hip-hop dance--improvisational dance (ID) and choreography learning (CL)--have distinct effects on individuals' inhibition, working memory, and creativity. A one-way repeated measures study design was adopted due to the limited num-ber of experienced dancers. Thirty participants were recruited to participate in the experiment. After the pre-test, participants were randomized to carry out either ID or CL for 45 minutes, fol-lowed immediately by a post-test. One week later, after accomplishing the other uncompleted dance session, participants completed the post-test again. The results showed both ID and CL had significant improvements on interference control and working memory, but only ID could im-prove participants’ creativity in convergent thinking，and only after CL session, the accuracy of behavioral inhibition decreased. The findings confirmed that different forms of dance training have distinctive impacts on a dancer's cognitive function and creativity.本研究探究了街舞的不同形式——即兴舞蹈（improvisational dance, ID）与编舞学习（choreography learning, CL）——是否会对个体的抑制能力、工作记忆与创造力产生差异化影响。由于资深舞者样本量有限，本研究采用单因素重复测量实验设计。本次实验共招募30名参与者参与。预测试结束后，参与者被随机分配开展45分钟的即兴舞蹈或编舞学习训练，随后即刻完成后测。一周后，参与者在完成另一项未参与过的舞蹈训练后，再次完成后测。研究结果显示，即兴舞蹈与编舞学习均能显著提升参与者的干扰控制能力与工作记忆水平，但仅即兴舞蹈能够提升参与者的聚合思维创造力；且仅在完成编舞学习训练后，行为抑制任务的准确率出现下降。本研究证实，不同形式的舞蹈训练对舞者的认知功能与创造力具有差异化影响。
