柔和背景音乐对脑力劳动绩效的影响

该文采用17项神经行为能力测试,定量地测量人员的感知、记忆、推理等多方面能力,并结合对情绪、烦躁度以及头疼等病态综合症状的主观问卷调查,通过实验研究了柔和背景音乐对人员脑力劳动绩效的影响。结果表明,柔和、慢节奏的背景音乐对人员脑力劳动绩效和情绪没有积极作用,相反,在背景音乐环境下受试者的不舒适、耳痛和头疼症状有所增加,其复杂脑力劳动任务的绩效显著下降。因此,对从事复杂的、认知资源需求较高的脑力劳动的人,其工作环境中不宜添加背景音乐。

The Effect of Soft Background Music on Performance of Mental Work

In this study,the effect of soft background music on mental work was investigated experimentally with 17 neurobehavioral tests that quantitatively examined subjects’ skills such as perception,memory and reasoning etc.,as well as with subjective assessments that related to subjects’feeling on mood,irritation,headache and other sick building syndrome（SBS） symptoms.No improvement in task performance or emotion was found when the soft,slow-tempo background music was present.Conversely,the symptoms such as discomfort,ear ache and headache etc.,were intensified and the performance of complex tasks decreased in the presence of background music.It is suggested that no background music should be presented when people are engaging in creative or complex tasks that are highly required in cognitive resources.
