ABSTRACT

This study examined effects of cognitive load on involuntary musical imagery (INMI), and particularly investigated whether INMI was accompanied by lyrics when a linguistic task was simultaneously performed. In the experiment, participants listened to a familiar lyrical song, and repeatedly engaged in a linguistic task or non-linguistic task for 30 s and had a break for 30 s between each trial. After completing all trials, they estimated the percentage of INMI time during the experiment. The results showed that INMI occurred more frequently during the rest periods than during the task periods, and the temporal percentage of INMI with lyrics was lower in the linguistic task than in the non-linguistic task. These results suggest that INMI tends to occur in low-attention states, and that the linguistic task interfered with the verbal information in INMI. However, due to the small sample size, these suggestions should be considered preliminary to further studies.

摘要

这项研究检查了认知负荷对非自愿音乐意象（INMI）的影响，并特别调查了当同时执行语言任务时INMI是否伴有歌词。在实验中，参与者聆听一首熟悉的抒情歌曲，并反复进行语言任务或非语言任务30 s，每次试验之间休息30 s。完成所有试验后，他们估计了试验期间INMI时间的百分比。结果表明，在休息期间，INMI的发生频率要比任务期间的发生频率高，在语言任务中，带有歌词的INMI的时间百分比要比在非语言任务中要低。这些结果表明，INMI倾向于在注意力低下的状态下发生，语言任务干扰了INMI中的口头信息。但是，由于样本量较小，因此应将这些建议视为进一步研究的初步建议。
