  • Learning when not to share

    Open Access•Matthew W Johnson, Julissa Muñiz et al.•ARTICLE•Qualitative Research•2026

    This article examines the ethical complexities of research data sharing through Reese's concept of ‘curtains’ and Tuck and Yang's notion of ‘refusal’, with reflexivity serving as the guiding methodology. It explores the tensions between transparency and the protection of intimate, sacred, or culturally sensitive knowledge, particularly within specific communities. Through a series of vignettes grounded in lived experiences, the authors illustrate…

  • Perpetual Projects of Potential

    Open Access•Daniel J Thomas, Matthew W Johnson et al.•ARTICLE•Urban Education•2026

    This literature review interrogates the genealogy of questions posed about Black men and boys in Urban Education from 1965 to 2025, tracing how policy eras have delimited their discursive framing within educational research. Drawing on Goldberg's (1993) racial knowledg e and Wynter's (1995) subjective understanding , we employ a Foucauldian genealogical analysis to examine four policy periods—from the Moynihan Report to George Floyd's racial reck…

  • Individuals recently abstinent from methamphetamine show selective cognitive and behavioral differences when compared to age-matched controls

    Open Access•M Frances Vest, Alexandru Mihai Dumitrescu et al.•ARTICLE•Frontiers in Psychiatry•2025

    These findings suggest that methamphetamine use disorder is associated with specific cognitive and behavioral abnormalities. Targeting these constructs in treatment may improve outcomes for individuals recovering from MUD

  • Shame, Guilt and Psychedelic Experience

    David S Mathai, Daniel E Roberts et al.•ARTICLE•Journal of Psychoactive Drugs•2025

    The classic psychedelic psilocybin has attracted special interest across clinical and non-clinical settings as a potential tool for mental health. Despite increasing attention to challenging psychedelic experiences, few studies have explored the relevance of shame-related processes with psychedelic use. This prospective, longitudinal study involved sequential, automated, web-based surveys that collected data from 679 adults planning to use psiloc…

  • Land Titling, Race, and Political Violence

    Ali T Ahmed, Matthew W Johnson et al.•ARTICLE•World Politics•2025•Cited by: 1

    Under what conditions do reforms prompt violent counterreform? Reform threatens elite interests in structurally unequal societies, prompting elites to use their power to counter reform. Although the existing literature demonstrates the material logic of counterreform, the authors build on critical race theory to argue that elites are more likely to target reforms meant for racially marginalized beneficiaries. The authors test this argument using …

  • Psychedelic and MDMA-Related Adverse Effects—A Call for Action

    Open Access•Otto Simonsson, Matthew W Johnson et al.•ARTICLE•JAMA Health Forum•2024

    This Viewpoint discusses the need to better understand potential risks associated with psychedelic and 3,4-methylenedioxymethamphetamine (MDMA) use to ensure safe and ethical practice and identifies 4 key research goals

  • A doctorate doesn’t make you a “Doc”

    Open Access•Matthew W Johnson, Anthony Johnson et al.•ARTICLE•Journal for Multicultural Education•2024•References: 18

    Purpose This study aims to stimulate scholarly attention and practical application pertaining to individuals recognized as “Docs.” Through conducting a comprehensive analysis and acquiring a profound understanding of its many connotations, the objective is to shift attitudes and approaches concerning those who are seen to possess knowledge and value within society. Design/methodology/approach For this study, culturally relevant pedagogies were us…

  • You’re nobody until somebody kills you

    Daniel J Thomas, Matthew W Johnson et al.•ARTICLE•Race Ethnicity and Education•2024•References: 9

    In this article, we utilized Charles Mills' racial contract and Derrick Bell's interest-convergence as theories to anchor our understanding of the exploitation of Black death to bolster institutional DEI efforts. We argue that mainstream forms of sociopolitical progress have emerged in the wake of Black death. In essence, Black death precedes and is necessary for the enactment – often performatively – of institutional social justice efforts. Acco…

  • Black Male Brilliance as (Ill)Legible

    Open Access•Martin P Smith, Matthew W Johnson et al.•ARTICLE•Urban Education•2024•Cited by: 2•References: 38

    In this study, we examine how race and racism impact the schooling of African American males by analyzing the first-person perspective of hip-hop superstar, Nasir “Nas” Jones. We selected Nas due to his unique yet prevalent educational trajectory and perspectives. Critical race theory is employed as a framework as well as notions of Sankofa methodology and literary analysis to investigate his music, documentaries, and an open letter whereby he cr…

  • Reducing Racial Asymmetries in the Survey Overestimation of Voter Turnout

    Open Access•David C Barker, Ray Block et al.•ARTICLE•Public Opinion Quarterly•2024•Cited by: 1•References: 21

    Research has consistently demonstrated that Black respondents are more likely than their White counterparts to overstate their plans or previous decisions to vote. We propose that by using a single question regarding turnout intention and candidate preference (rather than the typical approach of using two separate questions), survey researchers can reduce these racial asymmetries. The reason, we suggest, is that doing so encourages Black responde…

  • The 'absent Black father' metaphor

    Open Access•Daniel J Thomas, Matthew W Johnson et al.•ARTICLE•Discourse Studies in the Cultural…•2024•Cited by: 1•References: 37

    In this paper, we utilize the concepts of racial knowledge and subjective understanding to demonstrate how the metaphor of surrogacy encodes a racialized discourse via the epistemic authority of social science research. Taken together, we demonstrate how the pervasive use of surrogacy as a metaphor reflects the subjective understanding of Black male teachers produced through the racial knowledge of social science discourse. We argue that the meta…

  • Naturalistic psilocybin use is associated with persisting improvements in mental health and wellbeing

    Open Access•Sandeep M Nayak, Hillary Jackson et al.•ARTICLE•Frontiers in Psychiatry•2023

    Results from this study, the largest prospective survey of naturalistic psilocybin use to date, support the potential for psilocybin to produce lasting improvements in mental health symptoms and general wellbeing

  • Centering Black Perspectives Within the Social Studies Curriculum

    Daniel J Thomas, Terrance J Lewis et al.•ARTICLE•The Social Studies•2023•Cited by: 1•References: 12

    One justification given by social studies teachers for avoiding teaching or incorporating race into their lessons is the absence of race from textbooks. Given that textbooks continue to play a significant role in social studies instruction, the authors analyzed how Dr. Carter Godwin Woodson, a Black scholar of the early twentieth century, accounted for race in two of the textbooks he wrote for K–12 teachers. In this essay, we used the principles …

  • Introducing Curricular and Pedagogical Resuscitation (CPR)

    Open Access•Matthew W Johnson, Maureen W Nicol•ARTICLE•Urban Education•2023•Cited by: 5•References: 69

    Social studies has been lagging in the race to gain classroom instructional time due to the impact of high-stakes testing in urban schools. Furthermore, social studies can be particularly uninteresting to Black students whose diverse sociocultural histories and perspectives remain diminished or absent. Therefore, this paper advances curricular and pedagogical resuscitation (CPR) as a renewed and continuing quest to properly address and privilege …

  • Dynamics of Polarizing Rhetoric in Congressional Tweets

    Open Access•Andrew O Ballard, Ryan Detamble et al.•ARTICLE•Legislative Studies Quarterly•2023•Cited by: 31•References: 75

    Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric…

  • “But there is a God”

    Open Access•Matthew W Johnson, Marcus W Johnson•ARTICLE•Journal of Early Childhood Literacy•2022

    This study set out to gain a deeper understanding of how early childhood students, specifically Black boys in first and second grade, would respond to the teaching of historical figures and events traditionally omitted from classrooms. Contrary to general assumptions, these students were able to astutely contribute to classroom lessons, discussions, and interviews about Nat Turner, an enslaved Black American, who led a rebellion in 1831. Employin…

  • (Un)Natural Saviors and Motivators

    Daniel J Thomas, Matthew W Johnson et al.•ARTICLE•Educational Studies•2022•Cited by: 2•References: 43

    This article explores how Black male teachers in Hollywood films continue to be encoded with meanings derived from deficit social science discourse generated through a white-controlled epistemic order. Drawing from the framework of critical public pedagogy and utilizing the critical visual cultural tradition, we contend that the representation of Black male teachers on film is rooted in longstanding conceptual narratives of Black men and boys.

  • The Influence of Episodic Future Thinking and Graphic Warning Labels on Delay Discounting and Cigarette Demand

    Open Access•Gideon P Naudé, Sean B Dolan et al.•ARTICLE•International Journal of…•2021

    Delay discounting and operant demand are two behavioral economic constructs that tend to covary, by degree, with cigarette smoking status. Given historically robust associations between adverse health outcomes of smoking, a strong preference for immediate reinforcement (measured with delay discounting), and excessive motivation to smoke cigarettes (measured with operant demand), researchers have made numerous attempts to attenuate the extent to w…

    Open Access•Albert Garcia‐Romeu, A K Davis et al.•ARTICLE•Frontiers in Psychiatry•2020

    While these cross-sectional and self-report methods cannot determine whether psychedelics caused changes in drug use, results suggest the potential that psychedelics cause reductions in problematic substance use, and support additional clinical research on psychedelic-assisted treatment for SUD

    What it means to be a citizen for groups such as children and African Americans remains a contested, abstract, and evasive concept. This article seeks to gain a greater understanding of citizenship education by injecting the voices of young Black male students who are talked to and talked about but rarely asked to contribute to citizenship discourse. What emerged from these first- and second-grade students is the framework of “maybe citizens.” Th…

  • When the Mirage Fades

    Daniel J Thomas, Matthew W Johnson et al.•ARTICLE•Race Ethnicity and Education•2020•Cited by: 5•References: 12

    Private high schools are often viewed as bastions of scholastic and social opportunities, but the cost of tuition has rendered these sites predominantly white and more segregated than public schools. However, with the ability to recruit, Black boys have become prime targets of predominantly white private Catholic high schools seeking promising student-athletes. As a result, the population of Black boys at these schools are composed almost entirel…

    A within‐subject design, using human participants, compared delay discounting functions for real and hypothetical money rewards. Both real and hypothetical rewards were studied across a range that included $10 to $250. For 5 of the 6 participants, no systematic difference in discount rate was observed in response to real and hypothetical choices, suggesting that hypothetical rewards may often serve as a valid proxy for real rewards in delay disco…

  • Delay discounting in current and never-before cigarette smokers

    Forest Baker, Matthew W Johnson et al.•ARTICLE•Journal of Abnormal Psychology•2003

    Research has found that nicotine-dependent individuals delay discount monetary gains at a higher rate than matched controls. Delay discount rates, however, have also been found to vary across within-subject variables such as the magnitude of the outcome (e.g., 10 dollars or 1,000 dollars), whether the outcome constitutes a gain or a loss, and the commodity being evaluated (e.g., money or health). The present study comprehensively investigated the…
