Abstract
The global burden of early life adversity (ELA) is profound. The World Health Organization has estimated that ELA accounts for almost 30% of all psychiatric cases. Yet, our ability to identify which individuals exposed to ELA will develop mental illness remains poor and there is a critical need to identify underlying pathways and mechanisms. This review proposes unpredictability as an understudied aspect of ELA that is tractable and presents a conceptual model that includes biologically plausible mechanistic pathways by which unpredictability impacts the developing brain. The model is supported by a synthesis of published and new data illustrating the significant impacts of patterns of signals on child development. We begin with an overview of the existing unpredictability literature, which has focused primarily on longer patterns of unpredictability (e.g. years, months, and days). We then describe our work testing the impact of patterns of parental signals on a moment-to-moment timescale, providing evidence that patterns of these signals during sensitive windows of development influence neurocircuit formation across species and thus may be an evolutionarily conserved process that shapes the developing brain. Next, attention is drawn to emerging themes which provide a framework for future directions of research including the evaluation of functions, such as effortful control, that may be particularly vulnerable to unpredictability, sensitive periods, sex differences, cross-cultural investigations, addressing causality, and unpredictability as a pathway by which other forms of ELA impact development. Finally, we provide suggestions for prevention and intervention, including the introduction of a screening instrument for the identification of children exposed to unpredictable experiences.

Abstract
Urban life shapes the mental health of city dwellers, and although cities provide access to health, education and economic gain, urban environments are often detrimental to mental health1,2. Increasing urbanization over the next three decades will be accompanied by a growing population of children and adolescents living in cities3. Shaping the aspects of urban life that influence youth mental health could have an enormous impact on adolescent well-being and adult trajectories4. We invited a multidisciplinary, global group of researchers, practitioners, advocates and young people to complete sequential surveys to identify and prioritize the characteristics of a mental health-friendly city for young people. Here we show a set of ranked characteristic statements, grouped by personal, interpersonal, community, organizational, policy and environmental domains of intervention. Life skills for personal development, valuing and accepting young people's ideas and choices, providing safe public space for social connection, employment and job security, centring youth input in urban planning and design, and addressing adverse social determinants were priorities by domain. We report the adversities that COVID-19 generated and link relevant actions to these data. Our findings highlight the need for intersectoral, multilevel intervention and for inclusive, equitable, participatory design of cities that support youth mental health.

Abstract
Self-control is important for maintaining good health, acquiring achievement and happiness, and improving environmental adaptability. Trait self-control can affect the processing of emotional conflict in daily life and is associated with successful emotional regulation. In this study, the task functional magnetic resonance imaging (fMRI) technology was adopted to explore the emotion regulation processing and neural mechanism of individuals with different trait self-control levels. The results showed that: (a) Individuals with high self-control experienced the lower intensity of negative emotion when viewing negative emotional pictures than individuals with low self-control, showing spontaneous emotion regulation and significantly increased activity of executive control and emotion regulation networks of the brain; (b) Individuals with low self-control were more sensitive to negative emotion, and their emotion regulation effect under external instructions was better than that of individuals with high self-control. This suggests that individuals with high trait self-control were adept at using proactive control strategies to spontaneously regulate emotional conflict and experienced less emotional conflict accordingly. However, they were less effective than low self-control individuals in resolving emotional conflicts. These findings provide an important basis for our understanding of the nature and neural mechanism of self-control.
