In order to examine the neuropsychological effects of hostility on emotional and pain processing, auditory emotion perception before and after cold pressor pain in high and low hostile men was examined. Additionally, quantitative electroencephalography (QEEG) was recorded between each experimental manipulation. Results indicated that identification of emotion post cold pressor differed as a function of hostility level and ear. Primary QEEG findings indicated increased left temporal activation after cold pressor exposure and increased reactivity to cold pressor pain in the high hostile group. Low hostile men had a bilateral increase in high beta magnitude at the temporal lobes and a bilateral increase in delta magnitude at the frontal lobes after the cold pressor. Taken together, results from the dichotic listening task and the QEEG suggest decreased cerebral laterality and left hemisphere activation for emotional and pain processing in high hostile men.
为了研究敌意对情绪和疼痛处理的神经心理学影响，本研究在高、低敌意男性接受冷加压疼痛前后，考察了他们的听觉情绪感知能力。此外，在每次实验操作之间记录了定量脑电图（QEEG）。结果表明，情绪识别在冷加压后因敌意水平和耳的不同而有所差异。主要的 QEEG 结果表明，在冷加压暴露后，左颞叶的激活增加，而在高敌意组中，对冷加压疼痛的反应性增加。在冷加压后，低敌意男性的颞叶双侧高频β波幅增加，额叶双侧 δ 波幅增加。总的来说，来自双耳分听任务和 QEEG 的结果表明，高敌意男性的情绪和疼痛处理的大脑侧化和左半球激活减少。
