Higher face recognition ability in girls: Magnified by own-sex and own-ethnicity bias

Earlier studies on adults have shown sex differences in face recognition. Women tend to recognise more faces of other women than men do, whereas there are no sex differences with regard to male faces. In order to test the generality of earlier findings and to examine potential reasons for the observed pattern of sex differences, two groups of Swedish 9-year-old children (n = 101 and n = 96) viewed faces of either Swedish or Bangladeshi children and adults for later recognition. Results showed that girls outperformed boys in recognition of female faces, irrespective of ethnicity and age of the faces. Boys and girls recognised Swedish male faces to an equal extent, whereas girls recognised more Bangladeshi male faces than boys did. These results indicate that three factors explain the magnitude of sex differences in face recognition: an overall female superior face recognition ability, the correspondence between the sex of viewer and the gender of the face, and prior knowledge of the ethnicity of the face.     

Social influences on the emotion process

Philosophical and psychological theory has traditionally focused on intra-individual processes that are entailed in emotions. Recently sociologists, cultural anthropologists, and also social psychologists have drawn attention to the interpersonal nature of emotions. In this chapter we focus on the influence of others on emotional experiences and expressions. We summarise research on social context effects which shows that both emotional expression and experience are affected by the presence and expressiveness of other people. These effects are most straightforward for positive emotions, which are enhanced in the company of others. In the case of negative emotions, the effects of social context depend on the circumstances in which the emotion is elicited, and on the role of other persons in this situation. We discuss these social context effects in the light of a more general theoretical framework of social appraisal processes.     

Beyond smile dynamics: mimicry and beliefs in judgments of smiles

The judgment that a smile is based on "true," usually positive, feelings affects social interaction. However, the processes underlying the interpretation of a smile as being more or less genuine are not well understood. The aim of the present research was to test predictions of the Simulation of Smiles Model (SIMS) proposed by Niedenthal, Mermillod, Maringer, and Hess (2010). In addition to the perceptual features that can guide the judgment of a smile as genuine, the model identifies the conditions that the judgments rely on: (a) the embodiment of the facial expression and its corresponding state, and (b) beliefs about the situations in which genuine smiles are most often expressed. Results of two studies are consistent with the model in that they confirm the hypotheses that facial mimicry provides feedback that is used to judge the meaning of a smile, and that beliefs about the situations in which a smile occurs guides such judgments when mimicry is inhibited.     

Women's own-gender bias in face recognition memory

Women remember more female than male faces, whereas men do not seem to display an own-gender bias in face recognition memory. Why women remember female faces to a greater extent than male faces is unclear; one proposition is that women attend more to and thereby process female faces more effortfully than male faces during encoding. A manipulation that distracts attention and reduces effortful processing may therefore decrease women's own-gender bias by reducing memory for female faces relative to male faces. In three separate experiments, women and men encoded female and male faces for later recognition in full attention and divided attention conditions. Results consistently showed that women, in contrast to men, displayed a reliable own-gender bias. Importantly, the magnitude of women's own-gender bias was not reduced in divided attention conditions, indicating that it is not a result of effortful processing of female faces. We suggest these results reflect that women have greater perceptual expertise for female faces, facilitating recognition memory.     

Testing the limits of tolerance: how intergroup anxiety amplifies negative and offensive responses to out-group-initiated contact

Three studies examine the amplifying effects of intergroup anxiety on individuals' negative and offensive responses to out-group-initiated contact. Because intergroup anxiety typically results in avoidance of the initiation of intergroup contact, these studies explored how intergroup anxiety affected individuals' interpretation of and responses to out-group-initiated contact. The authors hypothesized that intergroup anxiety amplifies individuals' threat appraisal of out-group-initiated contact as well as their feelings of anger and offensive action tendencies toward the out-group. Results showed consistent support for these hypotheses by demonstrating that intergroup anxiety amplified individuals' threat appraisal (Studies 2 and 3), anger (Studies 1-3), and offensive action tendencies toward the out-group (Study 2). Anger consistently predicted offensive action tendencies (Studies 2-3). Thus, intergroup anxiety decreased individuals' limits of tolerance by increasing their threat appraisal of out-group-initiated contact. The results are discussed in relation to theories of threat, emotion, and tolerance.
