Four experiments confirmed the hypothesis that people discriminate the out-group on the basis of the expression of uniquely human emotions. In Study 1, using a lost e-mail paradigm, the expression of a uniquely human emotion resulted in "nicer" replies when the sender was an in-group compared with an out-group member. The same pattern of results was obtained in Studies 2 and 3 using a conformity paradigm. In addition, perceived similarity was measured and proposed as a potential underlying mechanism (Study 3). Finally, using an approach-avoidance procedure, Study 4 showed that people not only deprive the out-group of positive consequences as in the former studies but that people also act against the out-group. The role of infrahumanization underlying prejudice and discrimination is discussed.

).Humans tend to shift attention in response to the averted gaze of a face they are fixating, a phenomenon known as gaze cuing. In the present paper, we aimed to address whether the social status of the cuing face modulates this phenomenon. Participants were asked to look at the faces of 16 individuals and read fictive curriculum vitae associated with each of them that could describe the person as having a high or low social status. The association between each specific face and either high or low social status was counterbalanced between participants. The same faces were then used as stimuli in a gaze-cuing task. The results showed a greater gaze-cuing effect for high-status faces than for low-status faces, independently of the specific identity of the face. These findings confirm previous evidence regarding the important role of social factors in shaping social attention and show that a modulation of gaze cuing can be observed even when knowledge about social status is acquired through episodic learning.Keywords: attention; gaze cuing; social cognition INTRODUCTIONResearch has shown that individuals belonging to several species, including humans, tend to shift their attention in the direction gazed by conspecifics, a phenomenon reflecting orienting of social attention known as gaze cuing [1 -3]. Social attention is an essential ability for obtaining an empathic contact with others and to discover potentially relevant information in the environment [3].Although gaze cuing is a robust phenomenon that can be considered automatic in several regards [4,5], evidence is accumulating showing that it is sensitive to several social modulators. A pioneer animal study reported that submissive macaque monkeys (Macaca mulatta) showed a generalized gaze-cuing effect independently of whether the face stimulus depicted a high-or a low-status individual, whereas dominant macaque monkeys selectively followed the gaze of high-status individuals ([6], cf. [7] for a non-significant effect of social ranking on gaze following). Dominant-like exemplars, who are likely to have elevated testosterone levels, are more closely attended to and trigger stronger gaze-cuing effects. A related modulation has recently been demonstrated also in humans, who show greater gaze-cuing effects for

Humans tend to shift attention according to others' eye-gaze direction. This is a core ability as it permits to create pervasive relationships among individuals and with the environment around them. In the beginning, this form of social orienting was considered a reflexive phenomenon, but in recent years evidence has shown that it is also permeable to several social factors related to the observer, the individual depicted in the cueing face, and the relationship between them. The major goal of this work is to provide a comprehensive overview concerning the role that social variables can play in shaping covert gaze cueing in healthy adults, critically examining both the modulatory social factors for which evidence is more robust and those for which evidence is mixed. When available, overt attention studies will also be discussed. Finally, a novel theoretical framework linking these social and attention domains will be also introduced.

Two studies assessed the predictive validity of implicit political attitudes in relation to voting behavior. In Study 1, we demonstrated the validity of the adopted measure (i.e., the IAT;Greenwald, McGhee, & Schwartz, 1998)
