Table 1.
Behavioral measures of performance: Means of all behavioral measures and standard errors of the means in parentheses. Results of the ANOVA analysis for task effect (congruent versus incongruent trials) group effect (patients versus controls) and task by group interaction. All RT measures are for correct trials only. RTM: Mean Reaction Time in ms, RTSD: Standard Deviation of RT in ms, RTCV: Coefficient of Variation of RT (ratio no units), mu: Mean of the Gaussian component of the ex-Gaussian distribution of RT in ms, sigma: Standard deviation of the Gaussian component of the ex-Gaussian distribution of RT distribution in ms, tau: mean of the exponential component of ex-Gaussian distribution of RT in ms. Significant values with p < .05 are marked in bold.
