Modulation of Conflict Processing by Theta-Range tACS over the Dorsolateral Prefrontal Cortex
Table 2
Statistical analysis of the first experiment. The results of the GLMMs are shown for both accuracy and response time data of the first experiment. Additionally, the response times were divided according to the congruency of the previous trial in additional model runs. For every factor, the mean values and standard errors of each factor level are reported. The results of the statistical testing of the difference between these mean values are also reported as and values.
