The scrambled sentences test (SST), an experimental procedure that involves participants writing down their cognitions, has been used to elicit individual differences in depressiveness and vulnerability to depression. We describe here a modification of the SST to adapt it to computerized administration, with a particular view of its use in large samples and functional neuroimaging applications. In a first study with the computerized version, we reproduce the preponderance of positive cognitions in the healthy and the inverse association of these cognitions with individual measures of depressiveness. We also report a tendency of self-referential cognitions to elicit higher positive cognition rates. In a second study, we describe the patterns of neural activations elicited by emotional and neutral sentences in a functional neuroimaging study, showing that it replicates and extends previous findings obtained with the original version of the SST. During the formation of emotional cognitions, ventral areas such as the ventral anterior cingulus and the supramarginal gyrus were relatively activated. This activation pattern speaks for the recruitment of mechanisms coordinating motivational and associative processes in the formation of value-based decisions.
乱序句子测试（SST）是一种让参与者写下其认知的实验程序，已被用于揭示抑郁倾向和抑郁易感性方面的个体差异。我们在此描述了对SST的一种改进，使其适用于计算机化管理，尤其着眼于其在大样本和功能神经影像学应用中的使用。在第一项关于计算机化版本的研究中，我们重现了健康人群中积极认知的优势以及这些认知与抑郁个体测量指标之间的反向关联。我们还报告了自我参照认知引发更高积极认知率的一种趋势。在第二项研究中，我们描述了在一项功能神经影像学研究中，情感性句子和中性句子所引发的神经激活模式，表明它复制并扩展了使用SST原始版本所获得的先前研究结果。在情感认知形成过程中，腹侧区域如腹侧前扣带回和缘上回相对被激活。这种激活模式表明在基于价值的决策形成过程中，协调动机和联想过程的机制被调动起来。
