The promise and pitfalls of a strength-based approach to child poverty and neurocognitive development: Implications for policy

There has been significant progress in understanding the effects of childhood poverty on neurocognitive development. This progress has captured the attention of policymakers and promoted progressive policy reform. However, the prevailing emphasis on the harms associated with childhood poverty may have inadvertently perpetuated a deficit-based narrative, focused on the presumed shortcomings of children and families in poverty. This focus can have unintended consequences for policy (e.g., overlooking strengths) as well as public discourse (e.g., focusing on individual rather than systemic factors). Here, we join scientists across disciplines in arguing for a more well-rounded, "strength-based" approach, which incorporates the positive and/or adaptive developmental responses to experiences of social disadvantage. Specifically, we first show the value of this approach in understanding normative brain development across diverse human environments. We then highlight its application to educational and social policy, explore pitfalls and ethical considerations, and offer practical solutions to conducting strength-based research responsibly. Our paper re-ignites old and recent calls for a strength-based paradigm shift, with a focus on its application to developmental cognitive neuroscience. We also offer a unique perspective from a new generation of early-career researchers engaged in this work, several of whom themselves have grown up in conditions of poverty. Ultimately, we argue that a balanced strength-based scientific approach will be essential to building more effective policies.

Race, academic achievement and the issue of inequitable motivational payoff

As racial inequities continue to pervade school systems around the world, further research is necessary to understand the factors undergirding this pressing issue. Here across three studies conducted in the United States (N = 8,293), we provide evidence that race-based differences in student achievement do not stem from a lack of motivation among Black, Latinx and Indigenous (BLI) students, but a lack of equitable motivational payoff. Even when BLI and non-BLI students have the same levels of motivation, BLI students still receive maths grades that are an average of 9% lower than those of their non-BLI peers (95% confidence interval 7 to 11%). This pattern was not explained by differences in students' aptitude, effort or prior achievement but was instead linked to teachers' diminished expectations for their BLI students' academic futures. We conclude by discussing statistical power limitations and the implications of the current findings for how researchers consider the sources of, and solutions for, educational inequity.

Educators' Beliefs About Students' Socioeconomic Backgrounds as a Pathway for Supporting Motivation

Students' understandings of their socioeconomic status (SES) backgrounds have important implications for their motivation, achievement, and the emergence of SES-based educational disparities. Educators' beliefs about students' backgrounds likely play a meaningful role in shaping these understandings and, thus, may represent an important opportunity to support students from lower-SES backgrounds. We first experimentally demonstrate that educators can be encouraged to adopt background-specific strengths beliefs-which view students' lower-SES backgrounds as potential sources of unique and beneficial strengths (N_{Study 1} = 125). Subsequently, we find that exposure to educators who communicate background-specific strengths beliefs positively influences the motivation and academic persistence of students, particularly those from lower-SES backgrounds (N_{Study 2} = 256; N_{Study 3} = 276). Furthermore, lower-SES students' own beliefs about their backgrounds mediated these effects. Altogether, our work contributes to social-psychological theory and practice regarding how key societal contexts can promote equity through identity-based processes.

Concern about experiencing downward socioeconomic mobility generates precarious types of motivation among students of color

Students' beliefs about whether they will experience changes in their socioeconomic status influence their academic motivation. We propose that students who are concerned about downward socioeconomic mobility will focus their attention on negative academic outcomes and exhibit motivational goals oriented towards preventing negative possibilities and that this relationship will be particularly pronounced among students of color. Two studies investigated the relationship between college students' concerns about downward socioeconomic mobility and their adoption of academic achievement goals. The more that students of color expressed concerns about experiencing downward socioeconomic mobility, the more they adopted academic mastery-avoidance goals (β = 0.76), whereas there was no significant relationship between concerns about downward socioeconomic mobility and mastery-avoidance goals among White students (β = - 0.24; Study 1). Experimentally induced concerns about downward socioeconomic mobility increased academic mastery-avoidance goals among students of color (β =  - 0.58) but decreased mastery-avoidance goals among White students (β = 0.46; Study 2). Together, results indicate that there is a strong relationship between concerns about downward socioeconomic mobility and mastery-avoidance goals among students of color, highlighting the importance of understating how students of color make sense of their future socioeconomic prospects in order to most effectively support their academic trajectories positively.

Behavioural science is unlikely to change the world without a heterogeneity revolution

In the past decade, behavioural science has gained influence in policymaking but suffered a crisis of confidence in the replicability of its findings. Here, we describe a nascent heterogeneity revolution that we believe these twin historical trends have triggered. This revolution will be defined by the recognition that most treatment effects are heterogeneous, so the variation in effect estimates across studies that defines the replication crisis is to be expected as long as heterogeneous effects are studied without a systematic approach to sampling and moderation. When studied systematically, heterogeneity can be leveraged to build more complete theories of causal mechanism that could inform nuanced and dependable guidance to policymakers. We recommend investment in shared research infrastructure to make it feasible to study behavioural interventions in heterogeneous and generalizable samples, and suggest low-cost steps researchers can take immediately to avoid being misled by heterogeneity and begin to learn from it instead.

Beyond students: how teacher psychology shapes educational inequality

Although researchers investigating psychological contributors to educational inequality have traditionally focused on students, a growing literature highlights the importance of teachers' psychology in shaping disparities in students' educational achievement and attainment. In this review, we discuss recent advances linking teachers' attitudes, perceptions, and beliefs to inequality in students' outcomes. First, we identify specific aspects of teacher psychology that contribute to educational disparities, including teachers' biases, perceptions and expectations of students, beliefs about the nature of ability, and beliefs about group differences. Second, we synthesize mechanisms underlying the effects of teacher psychology on educational inequality, including teachers' disparate assessment of students' work and abilities, interpersonal interaction with students, and psychological impact on students. Implications for future research and interventions are discussed.

A Call for Greater Attention to Culture in the Study of Brain and Development

Despite growing research on neurobiological development, little attention has been paid to cultural and ethnic variation in neurodevelopmental processes. We present an overview of the current state of developmental cognitive neuroscience with respect to its attention to cultural issues. Analyses based on 80 publications represented in five recent meta-analyses related to adolescent developmental neuroscience show that 99% of the publications used samples in Western countries. Only 22% of studies provided a detailed description of participants' racial/ethnic background, and only 18% provided for socioeconomic status. Results reveal a trend in developmental cognitive neuroscience research: The body of research is derived not only mostly from Western samples but also from participants whose race/ethnicity is unknown. To achieve a holistic perspective on brain development in different cultural contexts, we propose and highlight an emerging interdisciplinary approach-developmental cultural neuroscience-the intersection of developmental psychology, cultural psychology, and cognitive neuroscience. Developmental cultural neuroscience aims to elucidate cultural similarities and differences in neural processing across the life span. We call attention to the importance of incorporating culture into the empirical investigation of neurodevelopment.
