Intergroup Perception and Cognition

Emotional Contrast and Psychological Function Impact Response Inhibition to Threatening Faces

Poor inhibitory control over negative emotional information has been identified as a possible contributor to affective disorders, but the distinct effects of emotional contrast and fearful versus angry faces on response inhibition remain unknown. In the present study, young adults completed an emotional go/no-go task involving happy, neutral, and either fearful or angry faces. Results did not reveal differences in accuracy or speed between angry and fearful face conditions. However, responses were slower and indicated poorer inhibition in blocks where threatening faces were paired with happy, versus neutral, faces. Results may reflect cognitive load of emotional valence contrast, such that higher contrast blocks (containing threatening with happy faces) produced more conflict and required more processing than lower contrast blocks (threatening with neutral faces). Preliminary findings also revealed higher anxiety and depression symptoms corresponded with slower responses and worse accuracy, consistent with patterns of adverse impacts of anxiety and depression on response inhibition to threatening faces, even at subclinical levels of symptomatology.

One of us? how facial and symbolic cues to own- versus other-race membership influence access to perceptual awareness

Information that conveys racial group membership plays a powerful role in influencing people's information processing including perceptual, memory and evaluative judgments. Yet whether own- and other-race information can differentially impact people's perceptual awareness at a preconscious level remains unclear. Employing a breaking continuous flash suppression (b-CFS) paradigm, we investigated whether compared with other-race stimuli, participants' own-race stimuli would be prioritized to gain privileged access to perceptual awareness. Across five experiments (N = 136), we firstly found that participants' own-race faces enjoyed privileged access to perceptual awareness (Experiment 1). In Experiments 2-5, we employed an associative training task to establish associations between otherwise arbitrary visual stimuli and own- vs. other-racial groups. Although otherwise arbitrary visual stimuli were prioritized to represent one's own race (vs. other-race) during the training, own- and other-race representing stimuli did not differ in their potency in entering perceptual awareness. This dissociation was further corroborated by Bayesian analyses and an internal meta-analysis. Taken together, our findings suggest that people's perceptual expertise with their own-race members' faces plays a determining role in shaping perceptual awareness. In contrast, newly learned race-representing stimuli did not influence early perceptual selection processes as indicated by the time they take to emerge into perceptual awareness.

Category-Based Learning About Deviant Outgroup Members Hinders Performance in Trust Decision Making

The present research examines whether individuation and categorization processes influence trust decisions about strangers at first and across repeated interactions. In a partial replication of the study reported by Cañadas et al. (2015), participants played an adaptation of the multi-round trust game paradigm and had to decide whether or not to cooperate with unknown partners. Gender (Study 1a) and ethnicity (Studies 1b, 2, and 3) served to create distinct social categories among the game partners, whose reciprocation rates were manipulated at group and individual levels. At the group level, two social groups (i.e., ingroup vs. outgroup) were associated with opposite reciprocation rates (i.e., high vs. low reciprocation rate). At the individual level, consistency was manipulated by altering the reciprocation rate of one out of four members of each social group. That is, there was one inconsistent individual in each group showing a pattern of reciprocation opposite to the group reciprocation rate. Our data, contrary to Cañadas et al.'s (2015) findings, suggested that ingroup partners were individuated given that participants made their decisions to cooperate with the trustees according to their individual reciprocation rate and independently of the group reciprocation rate. In contrast, decisions about outgroup partners (i.e., men in Study 1a and Blacks in Studies 1b, 2, and 3) were affected by category-based thinking. At the same time, in comparison with ingroup, greater cooperation was observed with ethnic outgroups but not with gender outgroups. The consistency of our results with the previous literature on social categorization and across the three experiments seems to indicate they are reliable, supporting the hypothesis that categorization and individuation processes guide trust decision-making, promoting individuation mainly for ingroup and categorization among outgroup members.

Recognizing Emily and Latisha: Inconsistent Effects of Name Stereotypicality on the Other-Race Effect

A person's name may activate social category information, which has been shown to lead to stereotyping and discrimination in various contexts. However, no previous research has investigated the influence of names on more basic processes of person perception. We present a set of seven experimental studies examining the influence of names on face recognition, namely, on the other-race effect (i.e., the relative difficulty to recognize outgroup faces). White-American participants completed online recognition tasks with White ingroup faces and Black or Chinese outgroup faces. Outgroup faces were presented with typical outgroup names versus typical White names; White faces were presented with typical White names versus infrequent names. We expected better recognition of outgroup faces with typical White names compared to outgroup faces with typical outgroup names. Employing an internal meta-analysis, we observe overall evidence of a small but significant effect (d_z = 0.11). However, the pattern of results across the seven studies is inconsistent. Given that particularly the high-powered pre-registered studies did not show an effect, we suggest that the effect should be interpreted with caution. We discuss that a small effect may still have important implications for real life as well as for theories of the ORE, emphasizing the importance of future research regarding the influence of name typicality on inter-group face perception.

The influence of skin colour on the experience of ownership in the rubber hand illusion

Racial prejudice is associated with a fundamental distinction between “us” and “them”—a distinction linked to the perceived overlap between representations of the self and others. Implicit prejudice has been shown to reduce the intensity of White individuals’ hand ownership sensation as induced by the Rubber Hand Illusion (RHI) with dark rubber hands. However, evidence for this link to implicit prejudice comes from self-report questionnaire data regarding the RHI. As an alternative, we assessed the onset time of the RHI. We hypothesized that onset time of the RHI would be higher for the black compared to the white RH, acting as the mediator between implicit prejudice and magnitude of the RH illusion and proprioceptive drift. As expected, participants took longer to incorporate the black RH and presented lower RH illusion magnitude and a smaller proprioceptive drift for the black RH. Mediation analysis revealed a significant indirect effect of implicit racial bias on proprioceptive drift and magnitude of illusion through onset time to illusion only for the black RH. These findings further illuminate the connection between implicit prejudice and embodied perception, suggesting new perspectives on how implicit biases operate.

Does Reducing Implicit Prejudice Increase Out-Group Identification? The Downstream Consequences of Evaluative Training on Associations Between the Self and Racial Categories

The present experiments were designed to investigate whether an intervention that targeted racial attitudes influenced not only prejudice but also self–Black associations. Because past research has demonstrated that people strive to build connections with favorable social categories, we predicted that positive evaluative training would increase identification with Blacks. Results from three studies provide evidence that practice in associating positive concepts with Blacks reduced implicit prejudice which in turn increased implicit self–Black associations. Notably, prejudice, in this case, had an intervening variable effect. Study 3 also investigated the impact of an alternative intervention that directly targeted self-associations rather than racial attitudes. Unlike evaluative training, associating the self with Blacks directly reduced both implicit prejudice and increased self–Black associations. These findings extend theorizing on the causal relationship between prejudice and out-group identification and provide important process information on how particular interventions reduce intergroup biases.

Habit in Personality and Social Psychology

Habits are largely absent from modern social and personality psychology. This is due to outdated perspectives that placed habits in conflict with goals. In modern theorizing, habits are represented in memory as implicit context–response associations, and they guide responding in conjunction with goals. Habits thus have important implications for our field. Emerging research shows that habits are an important mechanism by which people self-regulate and achieve long-term goals. Also, habits change through specific interventions, such as changes in context cues. I speculate that understanding of habits also holds promise for reducing intergroup discrimination and for understanding lay theories of the causes for action. In short, by recognizing habit, the field gains understanding of a central mechanism by which actions persist in daily life.

The iterative nature of person construal: Evidence from event-related potentials

Recently, a dynamic-interactive model of person construal (DI model) has been proposed, whereby the social categories a person represents are determined on the basis of an iterative integration of bottom-up and top-down influences. The current study sought to test this model by leveraging the high temporal resolution of event-related brain potentials (ERPs) as 65 participants viewed male faces that varied by race (White vs Black), fixating either between the eyes or on the forehead. Within face presentations, the effect of fixation, meant to vary bottom-up visual input, initially was large but decreased across early latency neural responses identified by a principal components analysis (PCA). In contrast, the effect of race, reflecting a combination of top-down and bottom-up factors, initially was small but increased across early latency principal components. These patterns support the DI model prediction that bottom-up and top-down processes are iteratively integrated to arrive at a stable construal within 230 ms. Additionally, exploratory multilevel modeling of single trial ERP responses representing a component linked to outgroup categorization (the P2) suggests change in effects of the manipulations over the course of the experiment. Implications of the findings for the DI model are considered.
