Abstract：
The CNV is analyzed in tasks related to EEG studies, often with participants presenting psychopathic personality traits. A systematic search of the literature was conducted, to solve some inconsistencies regarding CNV amplitude modulation by psychopathy. Nine studies (N = 317) were retrieved for analysis. Three meta-analyses were run - CNV, iCNV, tCNV. A qualitative analysis - reporting CNV amplitudes modulated by psychopathy dimensional features - was also featured. Overall effects for CNV and iCNV were not significant. Larger tCNV amplitudes were found in participants reporting higher psychopathy traits, g = -0.58, 95% CI [- 0.94, - 0.22]. These findings were surprising when confronted with previous assumptions in the literature, especially considering that no significant heterogeneity between studies was found. Neither of the studies\' characteristics was a significant moderator. Findings require the need to discuss key differences between adaptive/(mal)adjustment patterns in participants presenting psychopathic traits. Future studies dissociating iCNV and tCNV modulation by psychopathy, especially in community samples and through a dimensional lens, could help to better understand the construct of psychopathy.
摘要：
在与脑电图研究相关的任务中分析CNV，经常有参与者表现出精神病性格特征。对文献进行了系统的搜索，解决精神病引起的CNV调幅不一致的问题。检索到9项研究(N=317)用于分析。进行了三项荟萃分析-CNV，iCNV,tCNV。还进行了定性分析-报告由精神病尺寸特征调节的CNV幅度-。CNV和iCNV的总体效果不显著。在报告较高精神病特征的参与者中发现了较大的tCNV振幅，g=-0.58，95%CI[-0.94，-0.22]。当面对文献中先前的假设时，这些发现令人惊讶，特别是考虑到研究之间没有发现显著的异质性。这两个研究的特征都不是一个重要的调节因素。研究结果需要讨论呈现精神病特征的参与者的适应性/（正常）调整模式之间的关键差异。未来研究通过精神病分离iCNV和tCNV调节，特别是在社区样本中，通过维度镜头，可以帮助更好地理解精神病的结构。
