在人类脑电图α波段的皮质活动进行了测量（通过事件相关的方法）在前和后测试（中间培训），而参与者（n = 30）面临着发散思维的任务。一半的参与者接受了发散性思维训练（超过2周的时间），其中包括结构上类似于前测试和后测试中使用的练习。分析显示，训练组显示出比对照组更高的任务相关的额叶α活动同步（即从刺激前参考到激活间隔的α功率增加）。这些发现与额叶α同步化的观点一致，认为这是一种选择性的自上而下的抑制过程，可以防止内部或自上而下的信息处理受到外部输入的干扰。
Cortical activity in the human electroencephalogram alpha band was measured (by means of an event-related approach) in a pre- and a post-test (with intermediate training) while participants (n = 30) were confronted with divergent thinking tasks. Half of the participants received a divergent thinking training (over a time period of 2 weeks) which was composed of exercises structurally similar to those used in the pre- and post-test. Analyses revealed that the training group displayed higher task-related synchronization of frontal alpha activity (i.e. increases in alpha power from the pre-stimulus reference to the activation interval) than the control group. These findings are in line with the view of frontal alpha synchronization as a selective top-down inhibition process that prevents internal or top-down information processing being disturbed by incoming external input.
