An experiment examined the potency of nostalgia-a sentimental longing for one's past-to facilitate detection of death-related stimuli, using functional magnetic resonance imaging (fMRI) and behavioral techniques (i.e., judgmental accuracy, reaction times). We hypothesized and found that, at the neural level, nostalgic (relative to control) participants evinced more intense activation in right amygdala in response to death-related (vs. neutral) words. We also hypothesized and found that, at the behavioral level, nostalgic (relative to control) participants manifested greater accuracy in judging whether two death-related (vs. neutral) words belonged in the same category. Exploratory analyses indicated that nostalgic (relative to control) participants did not show faster reaction times to death-related (vs. neutral) words. In all, nostalgia appeared to aid in death threat detection. We consider implications for the relevant literatures.
一项实验使用功能磁共振成像（fMRI）和行为技术（即判断准确性、反应时间），考察了怀旧（对过去的感伤渴望）促进对与死亡相关刺激的检测的效力。我们假设并发现，在神经水平上，与控制组相比，怀旧组参与者对与死亡相关（相对于中性）的词语的反应更强烈，右杏仁核的激活程度更高。我们还假设并发现，在行为水平上，与控制组相比，怀旧组参与者在判断两个与死亡相关（相对于中性）的词是否属于同一类别时表现出更高的准确性。探索性分析表明，与控制组相比，怀旧组参与者对与死亡相关（相对于中性）的词语的反应时间没有更快。总之，怀旧似乎有助于发现死亡威胁。我们考虑了这对相关文献的影响。
