This study explored the role of culture in shaping music perception and memory. We tested the hypothesis that listeners demonstrate different patterns of activation associated with music processing-particularly right frontal cortex-when encoding and retrieving culturally familiar and unfamiliar stimuli, with the latter evoking broader activation consistent with more complex memory tasks. Subjects (n = 16) were right-handed adults born and raised in the USA (n = 8) or Turkey (n = 8) with minimal music training. Using fMRI procedures, we scanned subjects during two tasks: (i) listening to novel musical examples from their own culture and an unfamiliar culture and (ii) identifying which among a series of brief excerpts were taken from the longer examples. Both groups were more successful remembering music of their home culture. We found greater activation for culturally unfamiliar music listening in the left cerebellar region, right angular gyrus, posterior precuneus and right middle frontal area extending into the inferior frontal cortex. Subjects demonstrated greater activation in the cingulate gyrus and right lingual gyrus when engaged in recall of culturally unfamiliar music. This study provides evidence for the influence of culture on music perception and memory performance at both a behavioral and neurological level.
本研究探讨了文化在塑造音乐感知和记忆中的作用。我们测试了这样一个假设,即当编码和检索熟悉和不熟悉的文化刺激时,听众表现出与音乐处理相关的不同激活模式,特别是右额叶皮层,后者引起与更复杂的记忆任务相关的更广泛的激活。受试者(n = 16)为右利手成年人,在美国(n = 8)或土耳其(n = 8)出生和长大,接受过最少的音乐训练。使用 fMRI 程序,我们在两个任务中扫描了受试者:(i)听来自他们自己文化和不熟悉文化的新音乐示例,以及(ii)识别一系列简短摘录中哪些来自较长的示例。两组受试者对其本土文化的音乐记忆成功率更高。我们发现,对于不熟悉文化的音乐聆听,左小脑区域、右角回、后楔前回和右中额叶区域延伸至下额叶区域的激活更大。当受试者回忆不熟悉文化的音乐时,他们在扣带回和右舌回表现出更大的激活。这项研究提供了证据,证明文化在音乐感知和记忆表现方面具有行为和神经水平的影响。
