摘要 Stroop interference experiment is often used to investigate implementation and controlling ability. Combining the application of EEG in the cognitive field, EEG signals were induced by Stroop interference experiment. According to the complexity analysis of EEG with sample entropy as test parameter, the complexity changing rules of EEG were observed to establish the method of implementation and controlling ability identification by brain electrical. 35 college students were randomly selected to conduct the digitally Stroop interference test, and the EEG signals were acquired.The EEG complexity analysis results show that the sample entropy reduces firstly， and then rises with final normal level during the test process.For the Stroop interference test, the higher test score is, the smaller sample entropy reduction is. The statistics analysis shows that sample entropy change value and implementation and controlling ability are negatively correlated with significant correlation coefficient of -0.699.The brain electric signal complexity in the Stroop interference test can be used to response implementation and controlling ability.
