Although there is accumulating evidence for physiological and behavioral changes in response to emotion with age, little is known about developmental changes in response to emotion anticipation. Here, we investigated brain activations related to emotion anticipation and exposure, in participants aged between 19 and 54 years. During the anticipation of negative stimuli, a linear decrease of activation with age was detected in the rostral anterior cingulate cortex and brainstem; whereas exposure to negative stimuli revealed decreasing activation in a network of regions implicated in emotion processing and salience detection. The observed results might reflect reduced focusing on negative future events with age, and are in line with an age-related shift of motivational priorities for the pursuit of emotional satisfaction and well being.
尽管有越来越多的证据表明，随着年龄增长，机体对情绪的生理和行为反应会发生变化，但对于情绪预期的发育变化却知之甚少。在此，我们研究了19至54岁参与者中与情绪预期和暴露相关的大脑激活情况。在预期负面刺激期间，在前扣带回喙部和脑干中检测到激活随年龄呈线性下降；而暴露于负面刺激时，在涉及情绪处理和显著性检测的区域网络中发现激活减少。观察到的结果可能反映了随着年龄增长对负面未来事件的关注减少，这与追求情绪满足和幸福的动机优先级随年龄的转变是一致的。
