Callous-Unemotional (CU) traits are often associated with impairments in perspective taking and cognitive control (regulating goal directed behavior); and adolescents with CU traits demonstrate aberrant brain activation/connectivity in areas underlying these processes. Together cognitive control and perspective taking are thought to link mechanistically to explain CU traits. Because increased cognitive control demands modulate perspective taking ability among both typically developing samples and individuals with elevated CU traits, understanding the neurophysiological substrates of these constructs could inform efforts to alleviate societal costs of antisocial behavior. The present study uses GIMME to examine the heterogenous functional brain properties (i.e., connection density, node centrality) underlying cognitive control's influence on perspective taking among adolescents on a CU trait continuum. Results reveal that cognitive control had a negative indirect association with CU traits via perspective taking; and brain connectivity indirectly associated with lower CU traits - specifically the social network via perspective taking and conflict network via cognitive control. Additionally, less negative connection density between the social and conflict networks was directly associated with higher CU traits. Our results support the growing literature on cognitive control's influence on socio-cognitive functioning in CU traits and extends that work by identifying underlying functional brain properties.
冷酷无情(CU)特质通常与换位思考和认知控制(调节目标导向行为)的障碍有关;具有 CU 特质的青少年在这些过程所涉及的大脑区域表现出异常的大脑激活/连接。总的来说,认知控制和换位思考被认为在机制上是相关的,可以解释 CU 特质。由于认知控制需求的增加会调节典型发展样本和 CU 特质升高个体的换位思考能力,因此了解这些结构的神经生理基础可以为减轻反社会行为的社会成本提供信息。本研究使用 GIMME 来检查认知控制对 CU 特质连续体中的青少年换位思考的影响所基于的异质功能大脑特性(即连接密度、节点中心性)。结果表明,认知控制通过换位思考对 CU 特质有负向间接影响;而大脑连接性与较低的 CU 特质间接相关——特别是通过换位思考的社交网络和通过认知控制的冲突网络。此外,社会网络和冲突网络之间较少的负连接密度与较高的 CU 特质直接相关。我们的研究结果支持了关于认知控制对 CU 特质中社会认知功能影响的日益增多的文献,并通过确定潜在的功能大脑特性扩展了这项工作。
