研究了24名男性大学生对简单的非信号听觉音调和标志着RT前期开始的相似音调的皮层慢波和心率反应。在高强度和高信号条件下，皮质负性和双相心率反应幅度最大。初始加速和次级减速成分与皮层负性呈正相关。那些报告自己在任务中更警觉的人产生了更多的消极情绪。慢波活动也随眼球运动而变化，尽管眼球运动不能预测大脑皮层的反应。大脑的慢波反应系统地随心率事件而变化，这在理论上与注意力过程和激活有关。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Studied the cortical slow wave and cardiac rate of 24 male undergraduates in response to simple nonsignal auditory tones and to similar tones marking the onset of an RT foreperiod. Cortical negativity and the amplitude of the biphasic heart rate response were greatest under high-intensity and signal conditions. The initial acceleratory and secondary deceleratory components showed a positive correlation with cortical negativity. Ss who reported themselves to be more alert during the task yielded higher negativity. Slow-wave activity also covaried with eyeball movement, although eyeball movement did not predict the cortical response. The slow-wave response of the brain varies systematically with cardiac rate events which have been theoretically associated with attentional processes and activation.'19 ref.)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
