Core perception: re-imagining precocious reasoning as sophisticated perceiving sets out an impressive agenda that Spelke’s core knowledge theory is more appropriately called core perception. We raise two questions about this argument. First, why impose a distinct boundary between perception and cognition? Second, can investigations of core physics reveal new insights into how the mind bridges perception and cognition?

In Australia and around the world, young students are increasingly experiencing declines in wellbeing, engagement, and sense of belonging. These trends are accompanied by rising anxiety and social disconnection that affect learning and development. In response to these concerns, this study investigated whether a 10-week nature play intervention could support wellbeing, engagement, and learning in Year One students. A quasiexperimental mixed-methods design was used with students (N = 50; mean age = 6.87 years) from a metropolitan public primary school in Sydney, Australia. Participants were allocated to an intervention (n = 25) or a waitlist control group (n = 25). Data was collected at three time points: pre-intervention, post-intervention, and four-month follow-up. Quantitative measures included reading and mathematics results, and a student self-report questionnaire assessing play, nature connection, engagement, and wellbeing. Qualitative data comprised teacher and student journals, teacher interviews, parent surveys, and researcher observations. The results indicated significant improvement in mathematics, alongside children’s reported expressions of joy, autonomy, and emerging awareness of human–nature reciprocity. Despite limitations in sample size and context, these outcomes suggest that nature play supports holistic development while promoting a broader view of education that values wellbeing, engagement, and belonging alongside academic learning.

According to the Australasian Society for Developmental Paediatrics, experiential learning and outdoor play contain elements of risk, bravery, uncertainty, exploration, personal challenge, and adventure. These attributes are fundamental to a child’s growth, development, and wellbeing, and yet, in contemporary society, outdoor experiences have significantly declined. This scoping review explores the benefits and affordances of nature-based risky play and adventure education across early childhood and adolescence, asking what developmental opportunities emerge when children and adolescents engage in meaningful outdoor challenges. Adopting a benefit–risk approach where safety is “as safe as necessary” rather than “as safe as possible,” the review identifies common elements across developmental stages. A scoping review following PRISMA-ScR guidelines synthesised empirical studies (2015–2025). Our review included 40 empirical studies from a total of 5218 references, using diverse methodologies conducted predominantly in Western nations. All 40 studies reported positive associations across multiple developmental domains. Eight key themes developed: resilience and confidence, wellbeing, physical skills, autonomy and agency, nature connectedness, quality play provision, and educator influence. Authentic child agency and autonomy functioned as critical mechanisms through which benefits are realised across early childhood and school-aged populations. Key benefits included enhanced mental health, social competence, and anxiety prevention. Implementation barriers persist, including parental anxiety, institutional liability concerns, and cultural risk aversion. Evidence overwhelmingly supports nature-based risky play and outdoor adventure education as beneficial for child and adolescent development. Translation into practice remains limited by stakeholder attitudes and systemic barriers. Future research should prioritise longitudinal studies, cross-cultural investigation, and equity-focused approaches addressing disparities in access to positive risk-taking.

Analogical reasoning is the ability to recognise relations and apply them across contexts. Whether preschoolers reliably deploy relational reasoning remains debated, partly because behavioural measures provide only dichotomous outcomes (e.g., correct/incorrect). We investigated the temporal processes underlying relational decisions by combining the Relational Match-to-Sample task with time-resolved eye-tracking. Thirty-three 4–5-year-olds completed same/different judgments while their gaze patterns were continuously recorded. Children selected the relational match at levels that were significantly above chance performance. When children made relational choices, their gaze followed the sequence of an initial look to the relational match to establish alignment, a comparison of both alternatives, and a final return to the relational match to confirm the mapping, consistent with structure-mapping theory. The findings demonstrate that preschoolers can engage relational reasoning even when they do not express relational language and reveal the dynamic process that contributes to relational reasoning.

This study demonstrates that nature play meaningfully supports children’s well-being, engagement, sense of belonging, and connection to nature. Over 10 weeks, Year One students (n = 25) from a metropolitan government school in Sydney Australia, participated in a Bush School program, experiencing it as a space of joy, calm, challenge, and growth. Children came to see Bush School not as a break from learning but as a different kind of learning: active, relational, and purposeful. Using a quasi-experiment mixed-methods design, including reflective journals, self-report tools, and class assessments, the study found no negative impact on reading or mathematics outcomes, addressing concerns about lost instructional time. Instead, nature play enhanced number and algebra development, self-regulation, collaboration, and motivation to learn. The findings from this study highlight the potential of nature play to complement formal education in a developmentally appropriate way. Moreover, embedding nature play into mainstream schooling provides a timely and relevant response to current challenges facing education. The study also highlights the importance of listening to children as capable meaning-makers with valuable perspectives. In an era of growing pressure on children and schools, nature play invites a shift in mindset; to slow down, trust children, and embrace the natural world as a co-teacher.

Central to What Babies Know (Spelke, 2022) is the thesis that infants' understanding is divided into independent modules of core knowledge. As a test case, we consider adding a new domain: core knowledge of substances. Experiments show that infants' understanding of substances meets some criteria of core knowledge, and they raise questions about the relations that hold between core domains.
