【摘要】 为探究背景音乐对周边感知和警戒力的影响及人格差异的作用，基于周边感知和警戒力在安全相关场景中的重要性，本文以背景音乐和内外倾人格为自变量，周边感知和警戒力为因变量，选取内外倾被试各28名，采用维也纳心理实验系统(VTS),在安静和背景音乐环境下进行实验，并通过多元方差分析和独立样本T检验分析数据。结果表明：背景音乐对周边视野和跟踪偏差无显著主效应，但在背景音乐环境中，内外倾被试的周边感知呈现相反变化趋势，且跟踪偏差的交互作用显著(外倾被试跟踪偏差显著低于内倾被试);背景音乐对警戒力有显著正向影响。背景音乐对简单认知任务(如警戒力测试)的积极影响具有普遍性，而对周边感知的影响因人格特质存在差异。该结果为作业场景中背景音乐的合理应用提供了实证依据，对驾驶、雷达观察等职业领域具有一定的参考价值。更多还原

【Abstract】 To investigate the effects of background music on peripheral perception and alertness, as well as the role of personality differences, this study examines the importance of these psychological factors in safety-related scenarios. Using the Vienna Psychological Experiment System(VTS), we selected 28 participants with extraverted and introverted personalities as independent variables, with peripheral perception and alertness as dependent variables. The experiment was conducted in both quiet environments and music-accompanied settings, with data analysis performed through multivariate analysis of variance and independent samples T-tests.The results show that background music has no significant main effect on peripheral vision and tracking deviation, but in the background music environment, the peripheral perception of extraverted and introverted subjects showed opposite trends, and the interaction of tracking deviation was significant(extraverted subjects’ tracking deviation was significantly lower than introverted subjects). Background music has a significant positive effect on alertness. The positive effect of background music on simple cognitive tasks(such as alertness tests) is universal, while the effect on peripheral perception varies according to personality traits.The results provide an empirical basis for the reasonable application of background music in operational scenarios, and have certain reference value for professional fields such as driving and radar observation.更多还原
