本研究的目的是分析任务复杂性对脑电图谱参数的影响，以及年龄在多大程度上调节了这种关系。研究对象被分为初级组和高级组，分别参与简单和复杂的“去/不去”任务。认知、主观和电生理数据相结合。我们的研究结果表明，随着时间的推移，只有低年级组在简单任务中α功率增加，高年级组在复杂任务中α功率增加，这表明，随着年龄的增长，α波段的增加随任务复杂程度的不同而有不同的变化，可以反映出一些不同的现象。认知表现与年龄无关，但在动机的主要维度上，高年级学生得分更高，而且他们比低年级学生更少困倦。最后，本研究显示了认知表现、主观评价和电生理测量之间的相关性，以及它们对理解受试者的价值。
The purpose of the present study is to analyse the effects of task complexity on the EEG spectral parameters and the extent to which age modulates this relationship. Subjects were divided into a junior and a senior group and engaged in a simple and a complex version of “Go/No go” tasks. Cognitive, subjective and electrophysiological data were combined. Our results indicated that there was an increase in alpha power over time only in the junior group in the simple task and the senior group in the complex one, suggesting that, depending on age, the increase in alpha band vary in a different way according with the degree of task complexity and could reflect some different phenomena. Cognitive performance were independent of age but for the main dimensions of motivation, seniors had higher scores, and they were less sleepy than juniors. Finally, this study showed correlations between cognitive performance, subjective evaluations and electrophysiological measures, and their value for understanding the subject’...
