Abstract： Existing studies on the relationship between school connectedness and depression have produced inconsistent results. To clarify the extent to which school connectedness is associated with depression, and whether these associations differed according to the study or sample characteristics, a three-level meta-analysis of 87 included studies (206 effect sizes) was conducted. The results showed that there was a significant negative correlation between school connectedness and depression but only to a medium extent(r = –0.39, df = 205, p < 0.001). Additionally, the relationship between school connectedness and depression was found to be moderated by the percentage of female students, mean age of participants, measurement of depression, and data characteristics. No significant moderating effects were found for the measurement of school connectedness, culture, or publication year. School connectedness is a protective factor for depression. Interventions targeting depression should be aware of school connectedness.

Abstract： Implicit emotion regulation has become a hotspot of emotion regulation research recently. However, currently there is no standardized emotion regulation word system for researchers in the field of implicit emotion regulation. The purpose of this study is to establish a Chinese Emotion Regulation Word System (CERWS) by multi-dimensional ratings and analysis of emotional regulation words, and then to verify the effectiveness of the system by experiments.In Study 1, two hundred and twenty-six emotion regulation words (N = 226) were selected as preliminary materials by group discussion. Among them, 176 were judged as emotion regulation words that corresponded to five commonly used strategies (acceptance, distraction, venting, suppression and reappraisal) and 50 as neutral words. One hundred and twenty-eight participants (N = 128) rated the representativeness of words on five emotion regulation strategies. To ensure that the selected words are not mixed in strategic meanings, the words that exclusively represent one regulatory strategy or neutral meanings were selected into CERWS as emotion regulation words or neutral words, respectively. The words of CERWS were further rated by participants on the dimensions of valence, arousal, dominance, motivational tendency, familiarity and spelling complexity (N = 128). Thirty participants were randomly selected and retested one month later (N = 30). In Study 2, the emotion regulation effect of words in CERWS was further investigated. The regulatory effect of 5 strategies of CERWS on negative emotion was tested using a typical implicit emotion regulation paradigm (sentence unscrambling task). One hundred and ninety-six participants (N = 196) were involved in Study 2, who were divided into six groups (five implicit emotion regulation groups and one control group). Before viewing neutral and disgust pictures, the participants in implicit emotion regulation groups were required to complete the sentence unscrambling tasks to prime the emotion regulation strategy, while the participants in the control group were required to complete the sentence unscrambling task that was unrelated to emotion regulation. The CERWS was established in Study 1. One hundred and forty-nine emotion regulation words (N = 149) were selected into 6 groups (acceptance, distraction, venting, suppression, reappraisal and neutral) of CERWS. Comparing the attributes of emotion regulation words with those of neutral words, we found that five emotion regulation strategies had different affective connotation. For example, acceptance strategy was characterized by high pleasure, high dominance, high approach tendency and low arousal. In terms of gender differences, males were more pleasant with the words of distraction strategy, while females were more familiar with the words of acceptance strategy. The test-retest reliability was more than 0.7 after one month. The Cronbach’s α coefficients and Kendall’s coefficients of concordance of CERWS fit with relevant criteria. Moreover, results of Study 2 showed that implicit reappraisal and implicit suppression strategies decreased the emotional valence and arousal ratings significantly, and implicit distraction strategy decreased the emotional arousal ratings significantly.In conclusion, this study has established a standardized emotion regulation words system with good reliability. Moreover, this study has verified the regulatory effect of implicit reappraisal, suppression and distraction strategies on negative emotions, which provides a reference for the future use of the system.

Abstract： Emotion regulation is crucial to mental health and social life. Traditional view conceived emotion regulation as a deliberative process. However, there is growing evidence that emotion regulation can implement at an implicit level without or with limited involvement of the lateral prefrontal cortex (LPFC) that is responsible for cognitive control. Unlike explicit emotion regulation, we have few knowledge on the neural mechanisms underlying implicit emotion regulation. Here, we investigated the effect of excitatory the ventromedial prefrontal cortex (vmPFC) using transcranial direct current stimulation (tDCS) to provide causal evidence for the key role of the vmPFC in implicit emotion regulation. This study had a mixed design, with group (anodal vs. sham) as the between-subject factor and priming type (reappraisal vs. baseline) as the within-subject factor. A total of 80 participants were recruited and randomly assigned to the anodal group and the sham tDCS group. The task was divided into two blocks, i.e., the implicit reappraisal block and the baseline block. The order of the two blocks was counterbalanced within the participants in each group. At the beginning of each block, participants were required to complete a tDCS session (1.5 mA; 10 min for the active group and 1 min for the sham group). The anodal electrode was placed in the middle of Fz and Fpz and the ground electrode was placed under the chin). Then, participants completed six sessions of sentence unscramble task (10 trials per session) to prime the emotion regulation goal. Each session of the sentence unscramble task was followed by a picture viewing task (5 trials) to evoke negative emotions. The self-reported emotion rating and EEG signals were recorded during the picture viewing task. Half an hour after the end of the picture viewing task, participants were asked to rate the valence (1 = very unpleasant; 9 = very pleasant) of all viewed images in the picture viewing task. The results showed that the experimental group (n = 40) reported lower negative emotional experience and showed lower LPP amplitudes (measured as the average amplitude of Pz P3, P4, CP1, CP2) when the vmPFC was activated in the cognitive reappraisal block compared to the control group (n = 40), indicating that excitatory vmPFC could effectively facilitate the ability of implicit emotion regulation. Furthermore, we also found that excitatory vmPFC can reduce the P1 amplitude (measured as the average amplitude of O1, O2) under both baseline and reappraisal conditions. The above results indicated that activating the vmPFC could not only facilitate implicit emotion regulation but also reduce early attention distribution to negative stimuli. This study is the first attempt to use the tDCS technique to investigate priming-induced implicit emotion regulation. The results directly reveal the causal relationship between the vmPFC and implicit cognitive reappraisal, suggesting this brain region as a potential target of neural modulation to enhance the ability of implicit emotion regulation in clinical populations.

Abstract： The noninvasive functional magnetic resonance imaging (fMRI) technique has been a crucial method for brain imaging research. However, the divergence existing in the plethora of datasets acquired in the labs around the world limited the rate of progress of brain research. To address this issue, international brain scientists jointly proposed a framework named with the Brain Imaging Data Structure (BIDS) for organizing and describing neuroimaging data, and developed BIDS APPs for analyzing neuroimaging data organized in compliance with the BIDS. The present paper briefly introduced BIDS and the fMRI processing pipeline with BIDS APPs. Moreover, we discussed how to reasonably integrate the preprocessing pipeline with BIDS APPs (MRIQC and fmriprep) and the following statistical analysis. Specifically, we suggested that brain researchers should first organize their fMRI data in keeping with BIDS, and then use MRIQC APP to do automated quality control for both anatomical and functional MRI data organized in compliance with the BIDS. After eliminating the “bad data” (e.g., FD>0.2 mm), fmriprep can then be used to preprocess the “good data.” The fmriprep APP introduced two new preprocessing methods (ComCor and ICA-AROMA), which have been suggested to be effective in increasing sensitivity to group-level activation. However, it should be noted that the choice of fmriprep preprocessing methods determine which regressors should be included in the following individual general linear model (GLM). If only ComCor method was used, both the head motion related-noise (6 motion parameters) and cardiac and respiratory related-noise should be used as nuisance regressors in the following GLM analysis. If both ComCor and ICA-AROMA method were used, only regress cardiac and respiratory related-noise but not the head motion related-noise should be included in the following GLM analysis. This is because that ICA-AROMA method has removed the noise related to head motion in the preprocessed data, whereas ComCor did not. Therefore, regressing out motion-related variables in the GLM may reintroduce motion artifacts. We suggest that in the face of the emerging BIDS and BIDS APPs, brain researchers need to concern how to combine it with the traditional statistical software optimistically in order to attain a better statistical power.

Abstract： Cognitive automaticity is an inevitable road for human learning and improving. The traditional dichotomy view classifies cognitive processes intro controlled or automatic processes according to certain features of cognitive processes (e.g., unconsciousness). However, these features are not universal but up to the experimental paradigms used by researchers. New viewpoints based on the attentional resources theory were developed, taking the controlled-automatic process as a continuous dimension and regarding decreases of attentional resources as the central feature of the development of automaticity. Compared with dichotomy, the gradual view accords better with empirical findings. Further, the gradual view can be applied in both cognitive information processing and the stages model of skill acquisition theory, which confirmed the universality of gradual view.
