Recent studies have demonstrated that positive and negative affective reactivity can be predicted by resting electroencephalographic (EEG) asymmetry in frontal brain regions. These studies used different methods to assess asymmetry and affectivity. The goal of the present study was a conceptual replication of these results and to investigate their independence of employed procedures. Resting EEG of 37 subjects was recorded and affective slides were presented to obtain ratings of subjects' emotional reactions. Different procedures were applied to the data to assess the relation between asymmetries and affective reactivity. Depending on the particular analysis procedure, there were associations between anterior asymmetry and affectivity in line with the published findings, opponent to those findings, or no relation between anterior asymmetry and affective reactivity.
最近的研究表明，额叶脑区静息脑电图（EEG）不对称性能够预测积极和消极情感反应性。这些研究采用了不同方法来评估不对称性和情感性。本研究的目的是对这些结果进行概念性重复，并探究其与所采用程序的独立性。记录了37名受试者的静息脑电图，并呈现情感幻灯片以获取受试者情绪反应的评分。对数据应用了不同程序来评估不对称性与情感反应性之间的关系。根据具体的分析程序，前额叶不对称性与情感性之间存在符合已发表研究结果的关联、与那些结果相反的关联，或者前额叶不对称性与情感反应性之间无关联。
