This exploratory study investigates how hostile attribution biases for relationally provocative situations may be related to neurocognitive processing using the P300 event-related potential. Participants were 112 (45 women) emerging adults enrolled in a large, public university in upstate New York. Participants completed self-report measures on relational aggression and hostile attribution biases and performed an auditory perseveration task to elicit the P300. It was found that hostile attribution biases for relational provocation situations was associated with a larger P300 amplitude above and beyond the role of hostile attribution biases for instrumental situations, relational aggression, and gender. Larger P300 amplitude is interpreted to reflect greater allocation of cognitive resources or enhanced "attending" to salient stimuli. Implications for methodological approaches to studying aggression and hostile attribution biases and for theory are discussed, as well as implications for the fields of developmental psychology and psychopathology.
本探索性研究使用 P300 事件相关电位技术，调查了对关系挑衅情境的敌意归因偏差与神经认知加工之间的关系。参与者为 112 名（45 名女性）来自纽约州北部一所大型公立大学的新兴成年人。参与者完成了关于关系攻击和敌意归因偏差的自我报告测量，并进行了听觉持续任务以引出 P300。研究发现，对关系挑衅情境的敌意归因偏差与工具性情境、关系攻击和性别之外的更大的 P300 振幅有关。更大的 P300 振幅被解释为反映了对显著刺激的认知资源的更大分配或增强的“注意力”。讨论了对攻击性和敌意归因偏差研究的方法学方法以及对理论的影响，以及对发展心理学和精神病理学领域的影响。
