Happy to see me, aren't you, Sally?: Signal detection analysis of emotion detection in briefly presented male and female faces

Using signal detection methods, possible effects of emotion type (happy, angry), gender of the stimulus face, and gender of the participant on the detectionand response bias of emotion in briefly presented faces were investigated. Fifty-seven participants (28 men, 29 women) viewed 90 briefly presented faces(30 happy, 30 angry, and 30 neutral, each with 15 male and 15 female faces) answering yes if the face was perceived as emotional and no if it was not perceivedas emotional. Sensitivity [d’, z(hit rate) minus z(false alarm rate)] and response bias (b, likelihood ratio of ‘‘signal plus noise’’ vs. ‘‘noise’’) weremeasured for each face combination for each presentation time (6.25, 12.50, 18.75, 25.00, 31.25 ms). The d’ values were higher for happy than for angryfaces and higher for angry-male than for angry-female faces, and there were no effects of gender-of-participant. Results also suggest a greater tendency forparticipants to judge happy-female faces as emotional, as shown by lower b values for these faces as compared to the other emotion-gender combinations.This happy-female response bias suggests, at least, a partial explanation to happy-superiority effects in studies where performance is only measured as percentcorrect responses, and, in general, that women are expected to be happy.
