Recent research suggests that emotional music clips can serve as a highly successful tool for eliciting rich autobiographical memories, and that the utility of these cues may be related to their subjective familiarity. The current study was designed to examine the effects of familiarity on phenomenological characteristics and neural recruitment during retrieval of autobiographical memories elicited by musical cues. Further, we were interested in understanding how these effects differ as a function of age. In an event-related functional neuroimaging study, participants retrieved autobiographical memories associated with age-specific popular musical clips. Participants rated song familiarity, as well as the temporal specificity and emotional valence of each memory. Song familiarity was associated with increased dmPFC activity and ratings of temporal specificity and positivity across participants. In addition, behavioral and neuroimaging findings suggest age differences in familiarity-related effects in which familiarity was more associated with enhancement of memory detail in young adults and affective positivity in older adults. These findings highlight important age-related shifts in how individuals retrieve autobiographical events and how personally-relevant musical cues may be used to facilitate memory retrieval.
近期研究表明，情感音乐片段可作为唤起丰富自传体记忆的极为成功的工具，且这些线索的效用可能与其主观熟悉度有关。本研究旨在考察熟悉度对由音乐线索引发的自传体记忆检索过程中的现象学特征和神经激活的影响。此外，我们还想了解这些影响如何随年龄变化而不同。在一项事件相关功能神经成像研究中，参与者检索与特定年龄流行音乐片段相关的自传体记忆。参与者对歌曲熟悉度以及每个记忆的时间特异性和情感效价进行评分。歌曲熟悉度与全组参与者背内侧前额叶皮质（dmPFC）活动增加以及时间特异性和积极性评分相关。此外，行为学和神经成像结果表明，在与熟悉度相关的效应方面存在年龄差异，即熟悉度在年轻人中更与记忆细节增强相关，而在老年人中更与情感积极性相关。这些发现凸显了个体检索自传体事件方式以及个人相关音乐线索如何用于促进记忆检索方面与年龄相关的重要变化。
