In the first contrast there was an effect of valence, with faster RTs to emotionally valent stimuli in the emotion task (F(1, 95) = 24.62, p < 0.0001), and slower RTs to emotionally valent stimuli in the gender task (F(1, 95) = 5.93, p = 0.017). In the gender task there were two significant interactions: picture gender × valence (F(1, 95) = 18.21, p < 0.0001) where RTs were faster to emotional male faces compared to neutral male faces, and faster to neutral female faces compared to emotional female faces. The second interaction was picture gender × participant gender (F(1, 95) = 6.695 p = 0.011) with all participants responding faster to male pictures, but with the effect larger in females. In the emotion condition there was a significant interaction of picture gender × valence (F(1, 95) = 46.89, p < 0.0001), with participants being faster to emotional female pictures vs. emotional male pictures.
