Introduction
One of my lines of research pertains to the antecedents and consequences of self-bias in visual perception and perspective taking. I am also interested in how perceived social status shapes the way we see others and how the perceiver's social status shapes health outcomes. In both lines of research, I adopt a multi-level approach examining neural activity (e.g., fMRI, TMS) and behavioral responses at both the implicit and explicit levels. This integrative approach allows me to develop a more comprehensive understanding of biases attributable to self and others in various domains (e.g., Mattan, Kubota, & Cloutier, 2017: Perspectives on Psychological Science).

Full-text available
Self-relevant information is associated with facilitation of perceptual and memory processes. In 2 experiments, participants verified the number of dots within a virtual room that were visible to a given perspective, corresponding to participants' own first-person perspectives or the third-person perspectives for self- and other-associated avatars....
Article
Inferring the relative rank (i.e., status) of others is essential to navigating social hierarchies. A survey of the expanding social psychological and neuroscience literatures on status reveals a diversity of focuses (e.g., perceiver vs. agent), operationalizations (e.g., status as dominance vs. wealth), and methodologies (e.g., behavioral, neurosc...
Article
Full-text available
Previous behavioral and neuroimaging work indicates that individuals who are externally motivated to respond without racial prejudice tend not to spontaneously regulate their prejudice and prefer to focus on non-racial attributes when evaluating others. This fMRI multivariate analysis used Partial Least Squares (PLS) to examine the distributed neur...
Article
Generally, White (vs. Black) and high-status (vs. low-status) individuals are rated positively. However, implicit evaluations of simultaneously perceived race and socioeconomic status (SES) remain to be considered. Across four experiments, participants completed an evaluative priming task with face primes orthogonally varying in race (Black vs. Whi...
Article
Full-text available
Humans can rely on diverse sources of information to evaluate others, including knowledge (e.g., occupation, likes and dislikes, education, etc.) and perceptual cues (e.g., attractiveness, race, etc.). Previous research has identified brain regions supporting person evaluations, but are evaluations based on perceptual cues versus person-knowledge p...

Cigarette smoking continues to be a leading cause of preventable deaths in the U.S., in part because the U.S. has not adopted the World Health Organization Framework Convention on Tobacco Control, allowing the tobacco industry to counteract tobacco control policies. One way the tobacco industry in the U.S. counteracts tobacco control policies is by...
Article
Rational Overcoming the COVID-19 pandemic requires large-scale cooperation and behavior change on an unprecedented scale. Individuals can help reduce the burden of the pandemic by participating in behaviors that benefit people whose life circumstances make them especially vulnerable. Objective We tested the effect of reading narrative (i.e., story...

In commentaries about our article, “Perceiving social injustice during arrests of Black and White civilians by White police officers: An fMRI investigation” (Dang et al., 2022), Harris (2022), Niv and Kardosh (2022), and Purdie-Greenway and Spagna (2022) made suggestions to increase the generalizability of future research on this topic and cautione...
Article
Full-text available
From social media to courts of law, recordings of interracial police officer-civilian interactions are now widespread and publicly available. People may be motivated to preferentially understand the dynamics of these interactions when they perceive injustice towards those whose communities experience disproportionate policing relative to others (e....

Background: Lack of empathy is one of the main characteristics of narcissists. However, it is not clear whether there is a similar deficit in other facets of mentalizing, such as perspective-taking. Method: In this study, we measured the taking visual perspectives ascribed to different targets (e.g., first-person self, third-person self-avatar, and...
Article
Linguistic racism shapes the psychological antecedents of code switching and its consequences for Black people and other people of color. We highlight mentalizing as an antecedent of code switching. We posit that stereotype threat arises in contexts where racism is salient, prompting scrutiny of others’ mental states (i.e., mentalizing) when making...

Many challenges faced by humans require large-scale cooperation for communal benefits. We examined what motivates such cooperation in the context of social distancing and mask wearing to reduce the transmission intensity of the novel coronavirus (COVID-19). We hypothesized that collectivism, a cultural variable characterizing the extent that indivi...
Article
Full-text available
Evidence from social psychology suggests that men compared to women more readily display and pursue control over human resources or capital. However, studying how status and gender shape deliberate impression formation is difficult due to social desirability concerns. Using univariate and multivariate fMRI analyses (n = 65), we examined how gender...
Article
Full-text available
Although high status is often considered a desirable quality, this may not always be the case. Different factors may moderate the value of high status along a dimension such as wealth (e.g. gender, perceiver income/education). For example, studies suggest men may value wealth and control over resources more than women. This may be especially true f...
Article
Full-text available
Individuals high in socioeconomic status (SES) are often viewed as valuable members of society. However, the appeal of high-SES people exists in tension with our aversion to inequity. Little experimental work has directly examined how people rectify inequitable distributions between two individuals varying in SES. The objective of the present study...
Article
Conveying an impression of competence is important for jobseekers and politicians alike. New work from Oh, Shafir and Todorov suggests that subtle differences in clothing shape our impressions of how competent people are. In particular, subtly richer-looking clothes elicit greater perceived competence.
Article
Full-text available
The largely independent neuroscience literatures on race and status show increasingly that both constructs shape how we evaluate others. Following an overview and comparison of both literatures, we suggest that apparent differences in the brain regions supporting race-and status-based evaluations may tap into distinct components of a common evaluat...
Article
Full-text available
Those who are high in external motivation to respond without prejudice tend to focus on non-racial attributes when describing others (Norton, Sommers, Apfelbaum, Pura, & Ariely, 2006). This fMRI study examined the neural processing of race and an alternative yet stereotypically relevant attribute (viz., socioeconomic status: SES) as a function of t...
Article
Full-text available
This study investigated whether age-related sensitivity to self-relevance may benefit perspective-taking, despite generally poorer perspective-taking capacity in older adults. In one perceptual matching task and two visual perspective-taking paradigms, we examined age differences in sensitivity to avatars representing self and other. In the matchin...
Article
This study examined the extent to which visual perspective-taking performance is modulated by trait-level empathy. Participants completed a third-person visual perspective-taking task in which they judged the perspectives of two simultaneously presented avatars, designated “Self” and “Other.” Depending on the trial, these avatars either held the sa...

Commentary on the discussion paper, "Attentional control and the self: The Self-Attention Network (SAN)", by G. W. Humphreys and J. Sui. http://dx.doi.org/10.1080/17588928.2015.1044427 Abstract: Consistent with the authors' suggestions for research on extensions beyond the self (e.g., to joint attention and group-related processes), we offer the...

Violent video games are known to significantly increase aggressive thoughts, feelings and behavior (Anderson, Gentile & Buckley, 2007). The effects of a prosocial video game were examined here. here were three video game conditions: violent (killing bandits), helping (saving people from dying by administering medicine), or neutral (collecting bags...

Question
I'm working on an old but rather large fMRI dataset, and I noticed that some level-1 models included nuisance regressors that were not uniquely specified. This sometimes happens when the same design matrix is uniformly applied to all subjects but errors are not present for every subject*session combination, resulting in occasionally blank or empty columns in the design matrices. I don't intend on ever analyzing these nuisance regressors, but it would be useful to include them to account for error variance. My question is whether there are any adverse consequences for the estimation of beta maps that will be analyzed at subsequent stages of analysis if those beta maps are derived from a level-1 design that includes an empty nuisance regressor? If so, I'd want to update the scripts to remove those empty regressors and re-run them for any subjects with this problem.
