许多研究表明，知觉分组会影响对一系列音调中声音省略的前注意处理。然而，知觉分组和音乐经验是否影响声音省略的注意加工，目前尚不清楚。为此，我们创建了一系列大声（L）和柔和（S）的音调，分组为“LLSLLS......”，以及L和S音调的随机序列。L个音调的省略被伪随机地插入到随机序列中，并且存在其被插入的两个位置。对于组内遗漏，遗漏发生在"LLS"模式中的第一个L音之后。对于组间遗漏，将遗漏插入模式之间。音乐家和非音乐家的大脑对遗漏的反应是使用脑磁图测量的。在脑磁图测量中，被试在随机序列中检测遗漏的速度比在组序列中快。源分析表明，在随机序列中的遗漏比在组序列中引起更大的活动。音乐家的右下顶叶中发现了这种增加，而非音乐家的左上级颞回中发现了这种增加。这些结果表明，知觉分组的注意加工可能涉及左侧上级颞回或右侧顶叶下部，这取决于音乐经验。
Numerous studies have reported that perceptual grouping affects the pre‐attentive processing of sound omission in a sequence of tones. However, it remains unclear whether or not the perceptual grouping and musical experience affect the attentive processing of sound omission. To this end, we created a sequence of loud (L) and soft (S) tones grouped as ‘LLSLLS…’ and a random sequence of the L and S tones. The omission of the L tones was inserted pseudo‐randomly in the random sequence, and there were two positions at which it was inserted. For within‐group omission, the omission was after the first L tone within the ‘LLS’ pattern. For between‐group omission, the omission was inserted between the patterns. The brain response to the omission in musicians and non‐musicians was measured using magnetoencephalography. During the magnetoencephalography measurement, the subjects' performance in a task to detect the omission was faster in the random sequence than in the group sequence. Source analysis showed that the omission in the random sequence caused greater activity than that in the group sequence. The increase was found in the right inferior parietal lobe in musicians, whereas it was found in the left superior temporal gyrus in non‐musicians. These results suggest that the attentive processing of perceptual grouping might implicate the left superior temporal gyrus or right inferior parietal lobe, depending on musical experience.
