RESUMEN

Are members of marginalized communities silenced on social media when they share personal experiences of racism? Here, we investigate the role of algorithms, humans, and platform guidelines in suppressing disclosures of racial discrimination. In a field study of actual posts from a neighborhood-based social media platform, we find that when users talk about their experiences as targets of racism, their posts are disproportionately flagged for removal as toxic by five widely used moderation algorithms from major online platforms, including the most recent large language models. We show that human users disproportionately flag these disclosures for removal as well. Next, in a follow-up experiment, we demonstrate that merely witnessing such suppression negatively influences how Black Americans view the community and their place in it. Finally, to address these challenges to equity and inclusion in online spaces, we introduce a mitigation strategy: a guideline-reframing intervention that is effective at reducing silencing behavior across the political spectrum.

RESUMEN

Can training police officers on how to best interact with the public actually improve their interactions with community members? This has been a challenging question to answer. Interpersonal aspects of policing are consequential but largely invisible in administrative records commonly used for evaluation. In this study, we offer a solution: body-worn camera footage captures police-community interactions and how they might change as a function of training. Using this footage-as-data approach, we consider changes in officers' communication following procedural justice training in Oakland, CA, USA, one module of which sought to increase officer-communicated respect during traffic stops. We applied natural language processing tools and expert annotations of traffic stop recordings to detect whether officers enacted the five behaviors recommended in this module. Compared with recordings of stops that occurred prior to the training, we find that officers employed more of these techniques in posttraining stops; officers were more likely to express concern for drivers' safety, offer reassurance, and provide explicit reasons for the stop. These methods demonstrate the promise of a footage-as-data approach to capture and affect change in police-community interactions.

RESUMEN

Sharing experiences with racism (racial discrimination disclosure) has the power to raise awareness of discrimination and spur meaningful conversations about race. Sharing these experiences with racism on social media may prompt a range of responses among users. While previous work investigates how disclosure impacts disclosers and listeners, we extend this research to explore the impact of observing discussions about racial discrimination online-what we call vicarious race talk. In a series of experiments using real social media posts, we show that the initial response to racial discrimination disclosure-whether the response denies or validates the poster's perspective-influences observers' own perceptions and attitudes. Despite observers identifying denial as less supportive than validation, those who observed a denial response showed less responsive attitudes toward the poster/target (Studies 1-3) and less support for discussions about discrimination on social media in general (Studies 2-3). Exploratory findings revealed that those who viewed denial comments also judged the transgressor as less racist, and expressed less support and more denial in their own comments. This suggests that even as observers negatively judge denial, their perceptions of the poster are nonetheless negatively influenced, and this impact extends to devaluing the topic of discrimination broadly. We highlight the context of social media, where racial discrimination disclosure-and how people respond to it-may be particularly consequential.

RESUMEN

Calls for culture change abound. Headlines regularly feature calls to change the "broken" or "toxic" cultures of institutions and organizations, and people debate which norms and practices across society are now defunct. As people blame current societal problems on culture, the proposed fix is "culture change." But what is culture change? How does it work? Can it be effective? This article presents a novel social psychological framework for intentional culture change-actively and deliberately modifying the mutually reinforcing features of a culture. Synthesizing insights from research and application, it proposes an integrated, evidence-based perspective centered around seven core principles for intentional culture change: Principle 1: People are culturally shaped shapers, so they can be culture changers; Principle 2: Identifying, mapping, and evaluating the key levels of culture helps locate where to target change; Principle 3: Culture change happens in both top-down and bottom-up ways and is more effective when the levels are in alignment; Principle 4: Culture change can be easier when it leverages existing core values and harder when it challenges deep-seated defaults and biases; Principle 5: Culture change typically involves power struggles and identity threats; Principle 6: Cultures interact with one another and change can cause backlash, resistance, and clashes; and Principle 7: Timing and readiness matter. While these principles may be broadly used, here they are applied to the issue of social inequality in the United States. Even though culture change feels particularly daunting in this problem area, it can also be empowering-especially when people leverage evidence-based insights and tools to reimagine and rebuild their cultures.

RESUMEN

Across the United States, police chiefs, city officials, and community leaders alike have highlighted the need to de-escalate police encounters with the public. This concern about escalation extends from encounters involving use of force to routine car stops, where Black drivers are disproportionately pulled over. Yet, despite the calls for action, we know little about the trajectory of police stops or how escalation unfolds. In study 1, we use methods from computational linguistics to analyze police body-worn camera footage from 577 stops of Black drivers. We find that stops with escalated outcomes (those ending in arrest, handcuffing, or a search) diverge from stops without these outcomes in their earliest moments-even in the first 45 words spoken by the officer. In stops that result in escalation, officers are more likely to issue commands as their opening words to the driver and less likely to tell drivers the reason why they are being stopped. In study 2, we expose Black males to audio clips of the same stops and find differences in how escalated stops are perceived: Participants report more negative emotion, appraise officers more negatively, worry about force being used, and predict worse outcomes after hearing only the officer's initial words in escalated versus non-escalated stops. Our findings show that car stops that end in escalated outcomes sometimes begin in an escalated fashion, with adverse effects for Black male drivers and, in turn, police-community relations.

RESUMEN

Researchers have long used end-of-year discipline rates to identify punitive schools, explore sources of inequitable treatment, and evaluate interventions designed to stem both discipline and racial disparities in discipline. Yet, this approach leaves us with a "static view"-with no sense of how disciplinary responses fluctuate throughout the year. What if daily discipline rates, and daily discipline disparities, shift over the school year in ways that could inform when and where to intervene? This research takes a "dynamic view" of discipline. It leverages 4 years of atypically detailed data regarding the daily disciplinary experiences of 46,964 students from 61 middle schools in one of the nation's largest school districts. Reviewing these data, we find that discipline rates are indeed dynamic. For all student groups, the daily discipline rate grows from the beginning of the school year to the weeks leading up to the Thanksgiving break, falls before major breaks, and grows following major breaks. During periods of escalation, the daily discipline rate for Black students grows significantly faster than the rate for White students-widening racial disparities. Given this, districts hoping to stem discipline and disparities may benefit from timing interventions to precede these disciplinary spikes. In addition, early-year Black-White disparities can be used to identify the schools in which Black-White disparities are most likely to emerge by the end of the school year. Thus, the results reported here provide insights regarding not only when to intervene, but where to intervene to reduce discipline rates and disparities.

RESUMEN

Race is a social construct that contributes to group membership and heightens emotional arousal in intergroup contexts. Little is known about how emotional arousal, specifically uncertain threat, influences behavior and brain processes in response to race information. We investigated the effects of experimentally manipulated uncertain threat on impulsive actions to Black versus White faces in a community sample (n = 106) of Black and White adults. While undergoing fMRI, participants performed an emotional go/no-go task under three conditions of uncertainty: 1) anticipation of an uncertain threat (i.e., unpredictable loud aversive sound); 2) anticipation of an uncertain reward (i.e., unpredictable receipt of money); and 3) no anticipation of an uncertain event. Representational similarity analysis was used to examine the neural representations of race information across functional brain networks between conditions of uncertainty. Participants-regardless of their own race-showed greater impulsivity and neural dissimilarity in response to Black versus White faces across all functional brain networks in conditions of uncertain threat relative to other conditions. This pattern of greater neural dissimilarity under threat was enhanced in individuals with high implicit racial bias. Our results illustrate the distinct and important influence of uncertain threat on global differentiation in how race information is represented in the brain, which may contribute to racially biased behavior.

RESUMEN

The healthcare workforce in the United States is becoming increasingly diverse, gradually shifting society away from the historical overrepresentation of White men among physicians. However, given the long-standing underrepresentation of people of color and women in the medical field, patients may still associate the concept of doctors with White men and may be physiologically less responsive to treatment administered by providers from other backgrounds. To investigate this, we varied the race and gender of the provider from which White patients received identical treatment for allergic reactions and measured patients' improvement in response to this treatment, thus isolating how a provider's demographic characteristics shape physical responses to healthcare. A total of 187 White patients experiencing a laboratory-induced allergic reaction interacted with a healthcare provider who applied a treatment cream and told them it would relieve their allergic reaction. Unbeknownst to the patients, the cream was inert (an unscented lotion) and interactions were completely standardized except for the provider's race and gender. Patients were randomly assigned to interact with a provider who was a man or a woman and Asian, Black, or White. A fully blinded research assistant measured the change in the size of patients' allergic reaction after cream administration. Results indicated that White patients showed a weaker response to the standardized treatment over time when it was administered by women or Black providers. We explore several potential explanations for these varied physiological treatment responses and discuss the implications of problematic race and gender dynamics that can endure "under the skin," even for those who aim to be bias free.

RESUMEN

Children begin interacting less across racial lines around middle childhood, but it remains unclear why. We examine the novel possibility that, at that time, children's prejudice theories-their understanding of prejudice as a fixed or malleable attribute-begin to influence their desire for interracial affiliation. We devise immersive behavioral experiences to evaluate when and how prejudice theories affect interracial affiliation. Study 1 measured prejudice theories among 8-13-year-olds (N = 152; 76 White, 76 racial minority) and observed children in a newly-developed social interaction task. In line with our hypothesis, children older than 10 years with stronger malleable-prejudice theories exhibited more interest and affiliation in a simulated cross- (vs. same-race) interaction, regardless of their preexisting prejudice level. Study 2 randomly assigned children to listen to a fixed- or malleable-prejudice theory story before engaging in a real, first-time interaction with a same- or cross-race partner at a different school via live video-stream (N = 150; 96 White, 54 racial minority). The malleable theory increased children's interest in further interaction with their cross-race partner. These findings highlight the promise of malleable-prejudice theories for sustaining positive interracial relationships during a critical developmental window-when the frequency of cross-race friendships typically declines.

RESUMEN

When children return to school from juvenile detention, they face a severe stigma. We developed a procedure to orient educators and students toward each other as positive relationship partners during this period. In Study 1, through a structured exercise, students reentering school powerfully articulated to an educator of their choosing their prosocial hopes for school as well as challenges they faced. In a preliminary field trial (N = 47), presenting this self-introduction to this educator in a one-page letter via a third-party requesting the educator's help reduced recidivism to juvenile detention through the next semester from 69% to 29%. In Study 2 (preregistered), the letter led experienced teachers (N = 349) to express greater commitment to, anticipate more success for, and feel more love and respect for a student beginning their reentry into school, potentially initiating a better trajectory. The results suggest how relationship-orienting procedures may sideline bias and make school more supportive for students facing stigma.

RESUMEN

Research has shown that Black parents are more likely than White parents to have conversations about race with their children, but few studies have directly compared the frequency and content of these conversations and how they change in response to national events. Here we examine such conversations in the United States before and after the killing of George Floyd. Black parents had conversations more often than White parents, and they had more frequent conversations post-Floyd. White parents remained mostly unchanged and, if anything, were less likely to talk about being White and more likely to send colorblind messages. Black parents were also more worried than White parents-both that their children would experience racial bias and that their children would perpetrate racial bias, a finding that held both pre- and post-Floyd. Thus, even in the midst of a national moment on race, White parents remained relatively silent and unconcerned about the topic.

RESUMEN

How do routine police encounters build or undermine community trust, and how might they contribute to racial gaps in citizen perceptions of the police? Procedural justice theory posits that officers' interpersonal communication toward the public plays a formative role, but experimental tests of this hypothesis have been constrained by the difficulties of measuring and manipulating this dimension of officer-citizen interactions. Officer-worn body camera recordings provide a novel means to overcome both of these challenges. Across five studies with laboratory and community samples, we use footage from traffic stops to examine how officers communicate to drivers and whether racial disparities in officers' communication erode institutional trust in the police. Specifically, we consider the cumulative effects of one subtle interpersonal cue: an officer's tone of voice. In Studies 1A, 1B, and 1C, participants rated thin slices of officer speech. Participants were blind to the content of the officer's words and the race of their interlocutor, yet they evaluated officers' tone toward White (vs. Black) men more positively. By manipulating participants' exposure to repeated interactions, we demonstrate that even these paraverbal aspects of police interactions shape how citizens construe the police generally (Study 2), and that racial disparities in prosodic cues undermine trust in institutions such as police departments (Study 3). Participants' trust in the police, and personal experiences of fairness, in turn, correlated with their perceptions of officer prosody across studies. Taken together, these data illustrate a cycle through which interpersonal aspects of police encounters erode institutional trust across race.

RESUMEN

The race of an individual is a salient physical feature that is rapidly processed by the brain and can bias our perceptions of others. How the race of others explicitly impacts our actions toward them during intergroup contexts is not well understood. In the current study, we examined how task-irrelevant race information influences cognitive control in a go/no-go task in a community sample of Black (n = 54) and White (n = 51) participants. We examined the neural correlates of behavioral effects using functional magnetic resonance imaging and explored the influence of implicit racial attitudes on brain-behavior associations. Both Black and White participants showed more cognitive control failures, as indexed by dprime, to Black versus White faces, despite the irrelevance of race to the task demands. This behavioral pattern was paralleled by greater activity to Black faces in the fusiform face area, implicated in processing face and in-group information, and lateral orbitofrontal cortex, associated with resolving stimulus-response conflict. Exploratory brain-behavior associations suggest different patterns in Black and White individuals. Black participants exhibited a negative association between fusiform activity and response time during impulsive errors to Black faces, whereas White participants showed a positive association between lateral OFC activity and cognitive control performance to Black faces when accounting for implicit racial associations. Together our findings propose that attention to race information is associated with diminished cognitive control that may be driven by different mechanisms for Black and White individuals.

RESUMEN

Most adults are better at recognizing recently encountered faces of their own race, relative to faces of other races. In adults, this race effect in face recognition is associated with differential neural representations of own- and other-race faces in the fusiform face area (FFA), a high-level visual region involved in face recognition. Previous research has linked these differential face representations in adults to viewers' implicit racial associations. However, despite the fact that the FFA undergoes a gradual development which continues well into adulthood, little is known about the developmental time-course of the race effect in FFA responses. Also unclear is how this race effect might relate to the development of face recognition or implicit associations with own- or other-races during childhood and adolescence. To examine the developmental trajectory of these race effects, in a cross-sectional study of European American (EA) children (ages 7-11), adolescents (ages 12-16) and adults (ages 18-35), we evaluated responses to adult African American (AA) and EA face stimuli, using functional magnetic resonance imaging and separate behavioral measures outside the scanner. We found that FFA responses to AA and EA faces differentiated during development from childhood into adulthood; meanwhile, the magnitudes of race effects increased in behavioral measures of face-recognition and implicit racial associations. These three race effects were positively correlated, even after controlling for age. These findings suggest that social and perceptual experiences shape a protracted development of the race effect in face processing that continues well into adulthood.

RESUMEN

Of the $69.1 trillion global financial assets under management across mutual funds, hedge funds, real estate, and private equity, fewer than 1.3% are managed by women and people of color. Why is this powerful, elite industry so racially homogenous? We conducted an online experiment with actual asset allocators to determine whether there are biases in their evaluations of funds led by people of color, and, if so, how these biases manifest. We asked asset allocators to rate venture capital funds based on their evaluation of a 1-page summary of the fund's performance history, in which we manipulated the race of the managing partner (White or Black) and the strength of the fund's credentials (stronger or weaker). Asset allocators favored the White-led, racially homogenous team when credentials were stronger, but the Black-led, racially diverse team when credentials were weaker. Moreover, asset allocators' judgments of the team's competence were more strongly correlated with predictions about future performance (e.g., money raised) for racially homogenous teams than for racially diverse teams. Despite the apparent preference for racially diverse teams at weaker performance levels, asset allocators did not express a high likelihood of investing in these teams. These results suggest first that underrepresentation of people of color in the realm of investing is not only a pipeline problem, and second, that funds led by people of color might paradoxically face the most barriers to advancement after they have established themselves as strong performers.

RESUMEN

A hallmark of intergroup biases is the tendency to individuate members of one's own group but process members of other groups categorically. While the consequences of these biases for stereotyping and discrimination are well-documented, their early perceptual underpinnings remain less understood. Here, we investigated the neural mechanisms of this effect by testing whether high-level visual cortex is differentially tuned in its sensitivity to variation in own-race versus other-race faces. Using a functional MRI adaptation paradigm, we measured White participants' habituation to blocks of White and Black faces that parametrically varied in their groupwise similarity. Participants showed a greater tendency to individuate own-race faces in perception, showing both greater release from adaptation to unique identities and increased sensitivity in the adaptation response to physical difference among faces. These group differences emerge in the tuning of early face-selective cortex and mirror behavioral differences in the memory and perception of own- versus other-race faces. Our results suggest that biases for other-race faces emerge at some of the earliest stages of sensory perception.

RESUMEN

BACKGROUND: Health mindsets are mental frameworks that help people recognize, organize, interpret, and respond to health-relevant information. Although mindsets shape health behaviors and outcomes, no study has examined the health mindsets of ethnically and socioeconomically diverse Americans. PURPOSE: We explored the content, cultural patterning, and health correlates of diverse Americans' health mindsets. METHODS: Two studies surveyed approximately equal numbers of African American, Asian American, European American, and Latinx American men and women of lower and higher socioeconomic status (SES). Study 1 (N = 334) used open-ended questions to elicit participants' mindsets about the definitions, causes, and benefits of health. Study 2 (N = 320) used Study 1's results to develop a closed-ended instrument. RESULTS: In Study 1, open-ended questioning revealed six overarching mindset themes: behavioral, medical, physical, psychological, social, and spiritual. The most prevalent mindsets were psychological definitions, behavioral causes, and psychological benefits. Participants mentioned more cause themes than definition or benefit themes, and mindset theme mentions correlated with worse health. Older participants mentioned more themes than younger, women mentioned more definition themes than men, and low-SES participants mentioned more cause themes than high-SES participants. In Study 2, closed-ended scales uncovered more complex and positive health mindsets. Psychological and spiritual benefit mindsets correlated with good mental health. African Americans and women endorsed the widest array of mindsets, and the spiritual benefit mindset partially explained the superior mental health of African Americans. CONCLUSIONS: Many Americans hold simplistic, illness-focused health mindsets. Cultivating more complex, benefit-focused, and culturally appropriate health mindsets could support health.

RESUMEN

Using footage from body-worn cameras, we analyze the respectfulness of police officer language toward white and black community members during routine traffic stops. We develop computational linguistic methods that extract levels of respect automatically from transcripts, informed by a thin-slicing study of participant ratings of officer utterances. We find that officers speak with consistently less respect toward black versus white community members, even after controlling for the race of the officer, the severity of the infraction, the location of the stop, and the outcome of the stop. Such disparities in common, everyday interactions between police and the communities they serve have important implications for procedural justice and the building of police-community trust.

RESUMEN

People are better at remembering faces from their own race than other races-a phenomenon with significant societal implications. This Other Race Effect (ORE) in memory could arise from different attentional allocation to, and cognitive control over, same- and other-race faces during encoding. Deeper or more differentiated processing of same-race faces could yield more robust representations of same- vs. other-race faces that could support better recognition memory. Conversely, to the extent that other-race faces may be characterized by lower perceptual expertise, attention and cognitive control may be more important for successful encoding of robust, distinct representations of these stimuli. We tested a mechanistic model in which successful encoding of same- and other-race faces, indexed by subsequent memory performance, is differentially predicted by (a) engagement of frontoparietal networks subserving top-down attention and cognitive control, and (b) interactions between frontoparietal networks and fusiform cortex face processing. European American (EA) and African American (AA) participants underwent fMRI while intentionally encoding EA and AA faces, and ~24 hrs later performed an "old/new" recognition memory task. Univariate analyses revealed greater engagement of frontoparietal top-down attention and cognitive control networks during encoding for same- vs. other-race faces, stemming particularly from a failure to engage the cognitive control network during processing of other-race faces that were subsequently forgotten. Psychophysiological interaction (PPI) analyses further revealed that OREs were characterized by greater functional interaction between medial intraparietal sulcus, a component of the top-down attention network, and fusiform cortex during same- than other-race face encoding. Together, these results suggest that group-based face memory biases at least partially stem from differential allocation of cognitive control and top-down attention during encoding, such that same-race memory benefits from elevated top-down attentional engagement with face processing regions; conversely, reduced recruitment of cognitive control circuitry appears more predictive of memory failure when encoding out-group faces.

RESUMEN

Social psychologists have long demonstrated that people are stereotyped on the basis of race. Researchers have conducted extensive experimental studies on the negative stereotypes associated with Black Americans in particular. Across 4 studies, we demonstrate that the physical spaces associated with Black Americans are also subject to negative racial stereotypes. Such spaces, for example, are perceived as impoverished, crime-ridden, and dirty (Study 1). Moreover, these space-focused stereotypes can powerfully influence how connected people feel to a space (Studies 2a, 2b, and 3), how they evaluate that space (Studies 2a and 2b), and how they protect that space from harm (Study 3). Indeed, processes related to space-focused stereotypes may contribute to social problems across a range of domains-from racial disparities in wealth to the overexposure of Blacks to environmental pollution. Together, the present studies broaden the scope of traditional stereotyping research and highlight promising new directions. (PsycINFO Database Record
