讲座摘要：

Gratitude and pride are both feelings related to accomplishment, whereby pride attributes success to oneself and gratitude to another. Previous investigations of those higher-order social emotions with functional neuroimaging mainly focused on certain single emotions but little is known about their differential neural representations, how these positive emotions change over time based on learning from the environment, and the underlying computational mechanisms. By drawing on a novel social interaction task, fMRI and computational models, we test for differential neural substrates of the emotions gratitude and pride. We found that gratitude was more associated with neural activities in the bilateral temporoparietal junction (TPJ), which has previously been implicated in Theory of Mind. In contrast, pride was more associated with neural activities in the caudate nucleus, which is part of the reward system, and hippocampus. Activity in ventromedial prefrontal cortex (vmPFC) was related to an emotional prediction error signal, suggesting that this region might be involved in the process of updating the levels of gratitude and pride feelings. Our research identified neural substrates specific to gratitude and pride. Furthermore, the updating in values of gratitude and pride was similar to the reward learning that involves the mPFC. Our computational models showed that subjects’ received reward and certainty in their answers both contributed to feelings of gratitude and pride, but the benefactor’s actions were selectively contributing to building gratitude. Our learning model provides a mechanistic explanation of why people take help for granted after being exposed to a certain amount of help.
