Effects of background music on numerical and spatial location working memory: differences between extraverts and introverts
实验研究了背景音乐对外向者和内向者在数字和空间位置工作记忆任务上的影响，发现音乐对空间位置工作记忆有负面效应，且对内向者影响更大，但对数字工作记忆无显著影响。
This experimental research explored background music's influence on the performance of numerical and spatial location working memory of extraverts and introverts. Sixty participants (30 extraverts and 30 introverts) were asked to complete numerical and spatial location working memory tests, under the conditions of background music and silence. Results showed a main negative effect of background music on the participants' performance of spatial location working memory. A significant interaction effect between music and personality (extroversion and introversion) on this performance was also observed. It revealed that a more negative effect of music in introverts as compared with extroverts. In contrast, no main or interaction effect was observed for the performance of numerical working memory. According to the influence of music on working memory, introversion-extraversion personality factors of workers such as cashiers or drivers require consideration.
