Publication Social categories shape the neural representation of emotion: evidence from a visual face adaptation task
(Frontiers Media S.A., 2012) Otten, Marte; Banaji, MahzarinA number of recent behavioral studies have shown that emotional expressions are differently perceived depending on the race of a face, and that perception of race cues is influenced by emotional expressions. However, neural processes related to the perception of invariant cues that indicate the identity of a face (such as race) are often described to proceed independently of processes related to the perception of cues that can vary over time (such as emotion). Using a visual face adaptation paradigm, we tested whether these behavioral interactions between emotion and race also reflect interdependent neural representation of emotion and race. We compared visual emotion aftereffects when the adapting face and ambiguous test face differed in race or not. Emotion aftereffects were much smaller in different race (DR) trials than same race (SR) trials, indicating that the neural representation of a facial expression is significantly different depending on whether the emotional face is black or white. It thus seems that invariable cues such as race interact with variable face cues such as emotion not just at a response level, but also at the level of perception and neural representation.
Publication Children's Responses to Group-Based Inequalities: Perpetuation and Rectification
(Guilford Press, 2011) Olson, Kristina R.; Dweck, Carol S.; Spelke, Elizabeth; Banaji, MahzarinThe current studies investigate whether, and under what conditions, children engage in system-perpetuating and system-attenuating behaviors when allocating resources to different social groups. In three studies, we presented young children with evidence of social group inequalities and assessed whether they chose to perpetuate or rectify these inequalities. Children (aged 3.5–11.5 years) heard about two social groups (i.e., racial or novel groups) whose members received resources unequally (two cookies versus one). Participants were then given the opportunity to distribute additional resources to new members of the same groups. In Experiment 1, when children were presented with inequalities involving groups of Blacks and Whites, older children (aged 7.5–11.5 years) rejected the status quo, providing more resources to members of groups with fewer resources (White or Black), whereas younger children (aged 3.5–7.5 years) perpetuated the status quo. In Experiments 2 and 3, the inequalities involved Asians and Whites and novel groups. Children of all ages perpetuated inequality, with rectification strategies applied only by older children and only when Black targets were involved in the inequality. Equal sharing occasionally occurred in older children but was never a common response. These findings provide evidence that system-perpetuating tendencies may be predominant in children and suggest that socialization may be necessary to counter them.
Publication First Is Best
(Public Library of Science, 2012) Carney, Dana R.; Banaji, MahzarinWe experience the world serially rather than simultaneously. A century of research on human and nonhuman animals has suggested that the first experience in a series of two or more is cognitively privileged. We report three experiments designed to test the effect of first position on implicit preference and choice using targets that range from individual humans and social groups to consumer goods. Experiment 1 demonstrated an implicit preference to buy goods from the first salesperson encountered and to join teams encountered first, even when the difference in encounter is mere seconds. In Experiment 2 the first of two consumer items presented in quick succession was more likely to be chosen. In Experiment 3 an alternative hypothesis that first position merely accentuates the valence of options was ruled out by demonstrating that first position enhances preference for the first even when it is evaluatively negative in meaning (a criminal). Together, these experiments demonstrate a “first is best” effect and we offer possible interpretations based on evolutionary mechanisms of this “bound” on rational behavior and suggest that automaticity of judgment may be a helpful principle in clarifying previous inconsistencies in the empirical record on the effects of order on preference and choice.
Publication Judgements of the Lucky Across Development and Culture
(American Psychological Association, 2008) Olson, Kristina R.; Dunham, Yarrow; Dweck, Carol S.; Spelke, Elizabeth; Banaji, MahzarinFor millennia human beings have believed that it is morally wrong to judge others by the fortuitous or unfortunate events that befall them or by the actions of another person. Rather, an individual’s own intended, deliberate actions should be the basis of his/her evaluation, reward and punishment. In a series of studies we investigate whether such rules guide the judgments of children. The first three studies demonstrate that children view lucky others as more likely than unlucky others to perform intentional good actions. Children similarly assess the siblings of lucky others as more likely to perform intentional good actions than the siblings of unlucky others. The next three studies demonstrate that children as young as 3 years believe that lucky people are nicer than unlucky people. The final two studies find that Japanese children also demonstrate a robust preference for the lucky and their associates. These findings are discussed in relation to Lerner’s just world theory and Piaget’s immanent justice research and in relation to the development of intergroup attitudes.
Publication Evidence for hypodescent and racial hierarchy in the categorization and perception of biracial individuals.
(American Psychological Association (APA), 2011) Ho, Arnold K.; Sidanius, James; Levin, Daniel T.; Banaji, MahzarinIndividuals who qualify equally for membership in two racial groups provide a rare window into social categorization and perception. In 5 experiments, we tested the extent to which a rule of hypodescent, whereby biracial individuals are assigned the status of their socially subordinate parent group, would govern perceptions of Asian–White and Black–White targets. In Experiment 1, in spite of posing explicit questions concerning Asian–White and Black–White targets, hypodescent was observed in both cases and more strongly in Black–White social categorization. Experiments 2A and 2B used a speeded response task and again revealed evidence of hypodescent in both cases, as well as a stronger effect in the Black–White target condition. In Experiments 3A and 3B, social perception was studied with a face-morphing task. Participants required a face to be lower in proportion minority to be perceived as minority than in proportion White to be perceived as White. Again, the threshold for being perceived as White was higher for Black–White than for Asian–White targets. An independent categorization task in Experiment 3B further confirmed the rule of hypodescent and variation in it that reflected the current racial hierarchy in the United States. These results documenting biases in the social categorization and perception of biracials have implications for resistance to change in the American racial hierarchy.
Publication The Role of Forgetting in Undermining Good Intentions
(Public Library of Science, 2013) Olson, Kristina R.; Heberlein, Andrea S.; Kensinger, Elizabeth; Burrows, Christopher; Dweck, Carol S.; Spelke, Elizabeth; Banaji, MahzarinEvaluating others is a fundamental feature of human social interaction–we like those who help more than those who hinder. In the present research, we examined social evaluation of those who not only intentionally performed good and bad actions but also those to whom good things have happened (the lucky) and those to whom bad things have happened (the unlucky). In Experiment 1a, subjects demonstrated a sympathetic preference for the unlucky. However, under cognitive load (Experiment 1b), no such preference was expressed. Further, in Experiments 2a and 2b, when a time delay between impression formation (learning) and evaluation (memory test) was introduced, results showed that younger (Experiment 2a) and older adults (Experiment 2b) showed a significant preference for the lucky. Together these experiments show that a consciously motivated sympathetic preference for those who are unlucky dissolves when memory is disrupted. The observed dissociation provides evidence for the presence of conscious good intentions (favoring the unlucky) and the cognitive compromising of such intentions when memory fails.
Publication Constraints on the Acquisition of Social Category Concepts
(Informa UK Limited, 2014) Baron, Andrew Scott; Dunham, Yarrow; Banaji, Mahzarin; Carey, SusanDetermining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990; Gil-White, 2001), whereas others point to the role of noun labels as more general promoters of kind-based reasoning (Bigler & Liben, 2007; Gelman, 2003). A novel groups procedure was employed to examine the independent effects of noun labels and visual cues on social categorization. Experiment 1 demonstrated that in the absence of a visual cue, a noun label supported social categorization among 4-year-olds and 7-year-olds. Experiments 2 and 3 demonstrated that children and adults fail to differentiate between intrinsic and nonintrinsic visual cues to category membership, suggesting that this distinction is not central to the acquisition of social category concepts. Experiments 2 and 3 also showed that in the absence of a shared noun label, visual cues were not sufficient for younger children to form social categories. Experiment 4 ruled out a potential demand characteristic in the previous experiments. Together, these results reveal the primacy of verbal labels over visual cues for social categorization in young children and suggest a developmental change between ages 4 and 7 in the ability to construct new representations of social category concepts.
Publication The neuroscience of race
(Nature Publishing Group, 2012) Kubota, Jennifer T; Banaji, Mahzarin; Phelps, Elizabeth AAs the racial composition of the population changes, intergroup interactions are increasingly common. To understand how we perceive and categorize race and the attitudes that flow from it, scientists have used brain imaging techniques to examine how social categories of race and ethnicity are processed, evaluated and incorporated in decision-making. We review these findings, focusing on black and white race categories. A network of interacting brain regions is important in the unintentional, implicit expression of racial attitudes and its control. On the basis of the overlap in the neural circuitry of race, emotion and decisionmaking, we speculate as to how this emerging research might inform how we recognize and respond to variations in race and its influence on unintended race-based attitudes and decisions.
Publication Reply to Krueger: Good point, wrong paper
(Proceedings of the National Academy of Sciences, 2011) Stanley, Damian A.; Sokol-Hessner, Peter; Banaji, Mahzarin; Phelps, Elizabeth A.Publication Culture, Cognition, and Collaborative Networks in Organizations
(SAGE Publications, 2011) Srivastava, Sameer; Banaji, MahzarinThis article examines the interplay of culture, cognition, and social networks in organizations with norms that emphasize cross-boundary collaboration. In such settings, social desirability concerns can induce a disparity between how people view themselves in conscious (i.e., deliberative) versus less conscious (i.e., automatic) cognition. These differences have implications for the resulting pattern of intra-organizational collaborative ties. Based on a laboratory study and field data from a biotechnology firm, we find that (1) people consciously report more positive views of themselves as collaborative actors than they appear to hold in less conscious cognition; (2) less conscious collaborative–independent self-views are associated with the choice to enlist organizationally distant colleagues in collaboration; and (3) these self-views are also associated with a person’s likelihood of being successfully enlisted by organizationally distant colleagues (i.e., of supporting these colleagues in collaboration). By contrast, consciously reported collaborative–independent self-views are not associated with these choices. This study contributes to our understanding of how culture is internalized in individual cognition and how self-related cognition is linked to social structure through collaboration. It also demonstrates the limits of self-reports in settings with strong normative pressures and represents a novel integration of methods from cognitive psychology and network analysis.
