【摘要】 以往的研究发现:大脑伏隔核参与了期望收益的判断过程,继而影响了风险决策。但目前还没有研究表明,伏隔核结构是否与个体的其风险偏好有关。本研究通过使用"特定领域风险量表"以及"FIRST"软件包来研究:个体伏隔核体积差异是否可以导致不同的风险偏好。试验结果表明,伏隔核体积对个体金融风险偏好有一定贡献。更多还原

【Abstract】 Both mammal neurochemical and human imaging studies suggested that the nucleus accumbens(NAcc) could affect risk preference by expecting risk benefits.However,few studies addressed the relationship between individual financial risk preference and the NAcc structure in the brain.In this study,the contribution of the NAcc volume and individual financial risk preference was examined by the domain specific risk taking scale and FIRST imaging tool(FMRIB’s integrated registration and segmentation tool).The result suggested that the volume of NAcc may underlie human financial risk preference traits.更多还原
