Accuracy of face emotion identification. Across both adults and adolescents (N = 44), accuracy differs by emotion, depending on intensity level (Emotion × Intensity, F6,252 = 24.02, P < 0.001). Fifty percent intensity faces are less likely to be identified correctly than 75% or 100% intensity faces, and angry and fearful faces at 50% intensity are less likely to be identified correctly than 50% happy faces. Adults and adolescents do not differ in identifying emotions of different intensities (Age Group × Emotion × Intensity, F < 1, not shown). Brackets indicate significant pairwise comparisons (P < 0.05). Error bars indicate standard error.
