Social status gates social attention in humans

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.

The loyal member effect : On the preference for ingroup members who engage in exclusive relations with the ingroup

The goal of this article was to investigate an indirect form of intergroup differentiation in children in the context of racial attitudes: the preference for ingroup members who interact positively with other ingroup members rather than with outgroup members. Study 1 confirmed this general hypothesis with preschool and 1st-grade children, demonstrating that respondents preferred the ingroup member who played only with other ingroup members, evaluated this child more positively, and felt more similar to him or her. Studies 2 and 3 tested the boundary conditions of the phenomenon. Study 4 analyzed developmental changes demonstrating that the effect is no longer observed among 9- to 11-year-old children. Overall, these studies suggest that engaging in positive interactions with the outgroup might have its costs in terms of a relative devaluation and rejection by ones peers. Results are discussed by stressing the importance of intragroup processes for the regulation of intergroup relations among very young children.

A Group By Any Other Name—The Role of Entitativity in Group Perception

The social world consists of numerous and diverse groupings of people into meaningful and important collectives. As perceivers, we routinely encounter aggregates of people, some of which we endow with the property of groupness, and others we do not. Moreover, the variety of groups is enormous, yet perceivers differentiate among them and understand their properties. This chapter discusses how and why perceivers “see” an aggregate of persons as a group, the distinctions among different types of groups that perceivers detect, the variation among groups in their perceived groupness or entitativity, and the consequences that follow from perceiving a group as an entitative unit. The results of our research program addressing these issues are summarized, and implications for remaining unanswered questions are discussed.

Racial Group Membership Is Associated to Gaze-Mediated Orienting in Italy

Viewing a face with averted gaze results in a spatial shift of attention in the corresponding direction, a phenomenon defined as gaze-mediated orienting. In the present paper, we investigated whether this effect is influenced by social factors. Across three experiments, White and Black participants were presented with faces of White and Black individuals. A modified spatial cueing paradigm was used in which a peripheral target stimulus requiring a discrimination response was preceded by a noninformative gaze cue. Results showed that Black participants shifted attention to the averted gaze of both ingroup and outgroup faces, whereas White participants selectively shifted attention only in response to individuals of their same group. Interestingly, the modulatory effect of social factors was context-dependent and emerged only when group membership was situationally salient to participants. It was hypothesized that differences in the relative social status of the two groups might account for the observed asymmetry between White and Black participants. A final experiment ruled out an alternative explanation based on differences in perceptual familiarity with the face stimuli. Overall, these findings strengthen the idea that gaze-mediated orienting is a socially-connoted phenomenon.

On the Immediate Consequences of Intergroup Categorization: Activation of Approach and Avoidance Motor Behavior Toward Ingroup and Outgroup Members

The present research argues that intergroup categorization has immediate behavioral consequences. Specifically, intergroup categorization is hypothesized to prepare the organism to respond differently to ingroup and outgroup members so that approach-like motor movements should be faster toward ingroup- versus outgroup-related stimuli. In contrast, avoidance-like behavior should be facilitated when reacting to outgroup versus ingroup members. Studies 1 and 2 test the basic hypothesis in relation to ethnic, national, age, and political categorization. Study 3 uses a minimal group paradigm to test the hypothesis in relation to newly formed groups. Across these experiments, participants were generally faster in performing approach-like motor movements toward ingroup members or avoidance behaviors toward outgroup members. The evolutionary function and the cognitive underpinnings of this state of “physical readiness” to approach ingroup and avoid outgroup members are discussed.

On the automatic evaluation of social exemplars

The present article focuses on the automatic evaluation of exemplars whose category membership has been learned in the past. Studies 1 and 2 confirmed the hypothesis that once an exemplar has been encoded as a member of a given group, at a later encounter the evaluation associated with the group will be unintentionally retrieved from memory, even when no perceptual cue indicates the exemplars category membership. Study 3 extended the results to the domain of in-group/out-group differentiation. In addition. Studies 4 and 5 confirmed the hypothesis that stored evaluations can be retrieved and affect responses even when the semantic information on which the evaluations were originally based is no longer available for retrieval. Finally, Study 6 investigated spontaneous approach-avoidance behavior tendencies. Overall, results demonstrate the pervasive effects of person-based representations, and they are discussed in terms of recent models of person perception and out-group discrimination.

The Automatic Conservative: Ideology-Based Attentional Asymmetries in the Processing of Valenced Information

Research has widely explored the differences between conservatives and liberals, and it has been also recently demonstrated that conservatives display different reactions toward valenced stimuli. However, previous studies have not yet fully illuminated the cognitive underpinnings of these differences. In the current work, we argued that political ideology is related to selective attention processes, so that negative stimuli are more likely to automatically grab the attention of conservatives as compared to liberals. In Experiment 1, we demonstrated that negative (vs. positive) information impaired the performance of conservatives, more than liberals, in an Emotional Stroop Task. This finding was confirmed in Experiment 2 and in Experiment 3 employing a Dot-Probe Task, demonstrating that threatening stimuli were more likely to attract the attention of conservatives. Overall, results support the conclusion that people embracing conservative views of the world display an automatic selective attention for negative stimuli.

Eye gaze cannot be ignored (but neither can arrows)

Recent studies have tried to shed light on the automaticity of attentional shifts triggered by gaze and arrows with mixed results. In the present research, we aimed at testing a strong definition of resistance to suppression for orienting of attention elicited by these two cues. In five experiments, participants were informed with 100% certainty about the future location of a target they had to react to by presentation of either a direction word at the beginning of each trial or instructions at the beginning of each block. Gaze and arrows were presented before the target as uninformative distractors irrelevant for the task. The results showed similar patterns for gaze and arrows—namely, an interference effect when the distractors were incongruent with the upcoming target location. This suggests that the orienting of attention mediated by gaze and arrows can be considered as strongly automatic.

The spontaneous use of a group typology as an organizing principle in memory

Five studies investigated the spontaneous use of group typology in encoding information about various social groups. Participants saw faces or behaviors along with a label indicating the group membership of the face or the behavior. Labels corresponded to 2 groups each of 3 group types (i.e., 2 intimacy groups, 2 task-oriented groups, and 2 social categories). Recognition results showed more within-group-type errors than between-group-types errors. A free-recall task replicated these results, as the sequence of remembering items showed that memory organization reflected the group typology. A final study investigated the effects of group typology on the speed and accuracy of category membership verification. Results demonstrate the spontaneous use of an implicit group typology and its influence on the cognitive organization of information about groups.

Losing on all fronts: the effects of negative versus positive person-based campaigns on implicit and explicit evaluations of political candidates.

The current research investigated the effects of negative as compared to positive person-based political campaigns on explicit and implicit evaluations of the involved candidates. Participants were presented with two political candidates and statements that one of them ostensibly said during the last political campaign. For half of the participants, the campaign included positive remarks about the source of the statement (positive campaign); for the remaining half, the campaign included negative remarks about the opponent (negative campaign). Afterwards, participants completed measures of explicit and implicit evaluations of both candidates. Results indicate that explicit evaluations of the source, but not the opponent, were less favourable after negative as compared to positive campaigns. In contrast, implicit evaluations were less favourable for both candidates after negative campaigns. The results are discussed in terms of associative and propositional processes, highlighting the importance of associative processes in political decision making.
