新しい研究によると、私たちの頭から離れない曲は、単純な繰り返しが音楽の構造の一部である場合に起こります。また、最近聞いた音楽で、熟知している場合、または注意散漫な状態にある場合によく発生します。
この研究によって、意識や記憶についての洞察を提供することができます。また、不快な曲を取り除く方法に関する多くの理論がありますが、効果的な方法は、曲を完全に終了させる、他の曲を考える、または音楽または歌詞に関連する言葉や記憶から自分自身を取り除くことです。

耳に残る曲:なぜ、頭から離れない曲があるのか?(Ear-resistible: why there are some songs we simply can’t get out of our head)

Abstract

“Earworms” have been proposed as a particular type of involuntary musical imagery (INMI) where musical material is repeated in the mind. The structure of the repetition is investigated by proposing a spreading activation model (SAM), where mental experience consists of priming and activation of nodes that represent objects, events, and relationships, including music. Music consists of chaining together nodes representing small music segments within hierarchical structures. Listening to music at a point in time activates the music’s represented segment, which then primes the node representing the segment that follows. Repeating musical segments are coded recursively, with an additional layer of “context” nodes tracking global, structural location. From this basis, two hypotheses were proposed: H1 “Contiguous repetition at encoding” and H2 “Low environmental focus.” H1 predicts that when an INMI episode is a contiguously repeating segment, it must be based on music that contains contiguous repetition: it will be perceived as a subset of INMI – involuntary, limited, and contiguously repeating musical imagery (InLaCReMI). H1 challenges current views about preferred segments for looping, such as the “hook” of a tune. H2 predicts that InLaCReMI occurs when an individual is not focused on the immediate environment. In such a state there is less social imperative to activate high attentional-demand contextual information and so adherence to contextual integrity in thought is relaxed, leading to looping of recurrently activated nodes that were encoded with contiguous repetition. Additional predictions were made using SAM, demonstrating the potential for SAM to provide a unifying understanding of INMI. InLaCReMI is proposed as a frequently occurring species of INMI and confirmation of this phenomenon through more structured empirical investigation will provide novel insights into mental operation, and the nature of INMI.
