The Linear and Non-Linear Indices of EEG Changed in the Stroop Color and Word Test |
|
| چکیده انگلیسی مقاله |
Background: This study evaluated the brain activity based on the linear and nonlinear features of surface electroencephalography (EEG) in the Stroop Color and Word Test (SCWT) and the effect of learning in the test response and related EEG features.
Method: twenty-one women and nineteen men with general physical and mental health participated in this study. Four stages of this SCWT, consistently in the first and second stages and inconsistently in the third and fourth stages, were taken twice by the participants with a 10-min interval. Besides, EEG recording was simultaneously taken for 1 minute at each stage.
Results: The rate of correct responses in the inconsistent stages was lower than the consistent stages, while the delay of correct responses was more in them. EEG features showed that the relative power band of alpha 1 (8-10 Hz) frequency reduced during the test compared to the resting state. In contrast, the gamma 2 (40-50 Hz) frequency band showed a significant increase. There was no significant difference between various stages of the test and between two repetitions in the test indices and EEG features.
Conclusion: the relative power of alpha 1 and gamma 2 frequency bands changed during SCWT without considering the stage of test compared to the resting state. |
