完成任务的动机不仅受到任务预期结果的影响，还受到成功执行任务的信念的影响。随着时间的推移，个人积累的经验有助于形成对自己成功完成任务的整体能力的普遍信念，这被称为一般自我效能（GSE）。我们研究了区域灰质体积与GSE个体差异之间的关系。脑解剖分析使用磁共振图像获得64健康右撇子参与者完成Sherer的GSE量表。在控制了每个参与者的动机、年龄、性别和灰质总量等因素后，结果显示楔前叶后部区域灰质体积与GSE评分呈显著正相关。这些结果表明，一个人积累的成功和失败的经验，有助于GSE，也影响楔前叶的解剖特征。
Motivation in doing a task is influenced not only by the expected outcome of the task but also by the belief that one has in successfully executing the task. Over time, individuals accumulate experiences that contribute toward a general belief in one’s overall ability to successfully perform tasks, which is called general self-efficacy (GSE). We investigated the relationship between regional gray matter volume and individual differences in GSE. Brain anatomy was analyzed using magnetic resonance images obtained from 64 healthy right-handed participants who had completed Sherer’s GSE scale. After controlling for other factors related to motivation, age, sex, and total gray matter volume of each participant, results showed that regional gray matter volume in the posterior part of the precuneus significantly and positively correlated with the GSE score. These results suggest that one’s accumulated experiences of success and failure, which contribute toward GSE, also influence the anatomical characteristics of the precuneus.
