Some studies have indicated that a specific ‘social semantic network’ represents the social meanings of words. However, studies of the comprehension of complex materials, such as sentences and narratives, have indicated that the same network supports the online accumulation of connected semantic information. In this study, we examined the hypothesis that this network does not simply represent the social meanings of words but also accumulates connected social meanings from texts. We defined the social semantic network by conducting a meta-analysis of previous studies on social semantic processing and then examined the effects of social semantic accumulation using a functional Magnetic Resonance Imaging (fMRI) experiment. Two important findings were obtained. First, the social semantic network showed a stronger social semantic effect in sentence and narrative reading than in word list reading, indicating the amplitude of social semantic activation can be accumulated in the network. Second, the activation of the social semantic network in sentence and narrative reading can be better explained by the holistic social-semantic-richness rating scores of the stimuli than by those of the constitutive words, indicating the social semantic contents can be integrated in the network. These two findings convergently indicate that the social semantic network supports the accumulation of connected social meanings.

支持社会语义积累的大脑网络

一些研究表明，特定的“社会语义网络”代表了词语的社会意义。然而，对句子和叙述等复杂材料的理解研究表明，同一个网络支持连接语义信息的在线积累。在这项研究中，我们检验了这样一个假设，即这个网络不仅代表了单词的社会意义，而且还从文本中积累了相关的社会意义。我们通过对先前关于社会语义处理的研究进行荟萃分析来定义社会语义网络，然后使用功能性磁共振成像 (fMRI) 实验检查社会语义积累的影响。获得了两个重要发现。第一的，社会语义网络在句子和叙事阅读中表现出比单词列表阅读更强的社会语义效应，表明社会语义激活的幅度可以在网络中积累。其次，社会语义网络在句子和叙事阅读中的激活可以通过刺激的整体社会语义丰富度评分来更好地解释，而不是用构成词的得分来解释，表明社会语义内容可以整合到网络中。 . 这两个发现共同表明社会语义网络支持相关社会意义的积累。句子和叙事阅读中社会语义网络的激活可以通过刺激的整体社会语义丰富度评分来更好地解释，而不是用构成词的得分来解释，表明社会语义内容可以整合到网络中。这两个发现共同表明社会语义网络支持相关社会意义的积累。句子和叙事阅读中社会语义网络的激活可以通过刺激的整体社会语义丰富度评分来更好地解释，而不是用构成词的得分来解释，表明社会语义内容可以整合到网络中。这两个发现共同表明社会语义网络支持相关社会意义的积累。
