5月22日（周日）上午10點，浙江大學管理學院盛峰博士將為大家分享講座題目：Decomposing loss aversion from gazeallocation and pupil dilation（眼中讀腦：識別決策中的損失厭惡）的最新研究。相關(guān)研究成果已經(jīng)發(fā)表在國際頂刊《PNAS》。

摘要：Loss-averse decisions, in which one avoids losses at the expense of gains, are highly prevalent. However, the underlying mechanisms remain controversial. The prevailing account highlights a valuation bias that overweighs losses relative to gains, but an alternative view stresses aresponse bias to avoid choices involving potential losses.

Here we couple acomputational process model with eye-tracking and pupillometry to develop a physiologically grounded framework for the decision process leading to accepting or rejecting gambles with equal odds of winning and losing money.

Overall, loss-averse decisions were accompanied by preferential gaze toward losses and increased pupil dilation for accepting gambles. Using our model, we found gazeallocation selectively indexed valuation bias, and pupil dilation selectively indexed response bias.

Finally, we demonstrate that our computational model and physiological biomarkers canidentify distinct types of loss-averse decision makers who would otherwise be indistinguishable using conventional approaches.

Our study provides an integrative framework for the cognitive processes that drive loss-averse decisions and highlights the biological heterogeneity of loss aversion across individuals.
