Abstract

The aim of this study was to examine whether repeated victimization relates to differential processing of social exclusion experiences. It was hypothesized that experiences of repeated victimization would modulate neural processing of social exclusion in the insula, anterior cingulate cortex, and lateral prefrontal cortex. Furthermore, we hypothesized that repeated victimization relates positively to intentions to punish excluders. Exploratively, associations between neural processing and intentions to punish others were examined. The sample consisted of children with known victimization in the past two years (n = 82 (behavioral) / n = 73 (fMRI), 49.4

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance

【要点】：本研究探讨了遭受重复欺凌的儿童在经历社交排斥时的神经和行为反应，发现这些经历与insula、前扣带皮层和外侧前额叶皮层的神经处理差异相关，且与惩罚排斥者的意图呈正相关。

【方法】：研究采用功能性磁共振成像(fMRI)和行为测试来评估社交排斥经历对神经网络的影响以及与惩罚意图的关联。

【实验】：实验对象为过去两年内遭受欺凌的儿童（行为研究样本n=82，fMRI研究样本n=73），通过社交排斥任务来引发反应，并记录相关神经活动及后续的惩罚意图。
