Skin conductance responses in the SST.

<p>Skin conductance responses (SCR) to go (G), stop success (SS) and stop error (SE) trials in the SST. Data bars show SCR (mean ± S.E.) for men (n = 14) and women (n = 12) separately. Across all 26 subjects, G, SS and SE trials showed significant differences in SCR (p = 0.002, trial main effect, two-way ANOVA), as did planned comparisons: G vs. SS (p = 0.02), G vs. SE (p = 0.0002), and SS vs. SE (p = 0.0002), with two-sample t tests. There was also a gender main effect with men showing greater SCR than women (p = 0.009) but no interaction effect between trial and gender (p = 0.54).
