Music-evoked nostalgia has the potential to assist in recalling autobiographical memories and enhancing well-being. However, nostalgic music preferences vary from person to person, presenting challenges for applying nostalgia-based music interventions in clinical settings, such as a non-pharmacological approach. To address these individual differences, we developed the Nostalgia Brain-Music Interface (N-BMI), a neurofeedback system that recommends nostalgic songs tailored to each individual. This system is based on prediction models of nostalgic feelings, developed by integrating subjective nostalgia ratings, acoustic features and in-ear electroencephalographic (EEG) data during song listening. To test the effects of N-BMI on nostalgic feelings, state-level well-being, and memory recall, seventeen older and sixteen younger participants took part in the study. The N-BMI was personalized for each individual, and songs were recommended under two conditions: the "nostalgic condition", where songs were selected to enhance nostalgic feelings, and the "non-nostalgic condition", to reduce nostalgic feelings. We found nostalgic feelings, state-level well-being, and subjective memory vividness were significantly higher after listening to the recommended songs in the nostalgic condition compared to the non-nostalgic condition in both groups. This indicates that the N-BMI enhanced nostalgic feelings, state-level well-being, and memory recall across both groups. The N-BMI paves the way for innovative therapeutic interventions, including non-pharmacological approaches.
音乐引发的怀旧情绪有潜力帮助唤起自传体记忆并提升幸福感。然而，怀旧音乐偏好因人而异，这给在临床环境中应用基于怀旧情绪的音乐干预措施（如一种非药物方法）带来了挑战。为了应对这些个体差异，我们开发了怀旧脑-音乐接口（N-BMI），这是一种神经反馈系统，能推荐适合每个人的怀旧歌曲。该系统基于怀旧情绪的预测模型，通过整合歌曲聆听过程中的主观怀旧评分、声学特征和耳内脑电图（EEG）数据而开发。为了测试N-BMI对怀旧情绪、状态幸福感和记忆唤起的影响，17名老年人和16名年轻人参与了这项研究。N-BMI针对每个人进行了个性化设置，并在两种条件下推荐歌曲：“怀旧条件”，即选择歌曲以增强怀旧情绪；“非怀旧条件”，即选择歌曲以减少怀旧情绪。我们发现，与非怀旧条件相比，两组在怀旧条件下聆听推荐歌曲后，怀旧情绪、状态幸福感和主观记忆生动性均显著更高。这表明N-BMI在两组中均增强了怀旧情绪、状态幸福感和记忆唤起。N-BMI为创新治疗干预措施（包括非药物方法）铺平了道路。
