Working memory (WM) is a critical cognitive system that supports processing a variety of information. Remembering different types of objects may impose different levels of cognitive demands on WM performance. In the present study, we examined 205 children's WM in representing different types of content and its developmental trajectories in early…

Pretend play is often hypothesized in a global sense to be an effective context for young children's learning, but there is much still to learn about whether all types of information can be learned equally and whether all types of pretend play are equally beneficial. The present study tests whether preschoolers can learn a simple, novel causal…

The standard view on Theory of Mind (ToM) is that the mastery of the false belief (FB) task around age 4 marks the ontogenetic emergence of full-fledged meta-representational ToM. Recently, a puzzling finding has emerged: Once children master the FB task, they begin to fail true belief (TB) control tasks. This finding threatens the validity of FB…

We propose a simple computational model that describes potential mechanisms underlying the organization and development of the lexical-semantic system in 18-month-old infants. We focus on two independent aspects: (i) on potential mechanisms underlying the development of taxonomic and associative priming, and (ii) on potential mechanisms underlying…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

In many cultural contexts, judging another as conscious or not has profound practical, legal, and philosophical consequences. However, little research focuses on how our ability to make such judgements arises. Thirty years ago a classic set of studies by Flavell et al. demonstrated that children do not develop a complex understanding of conscious…

The notion of children's working theories is an overarching outcome of Aotearoa New Zealand's early childhood curriculum document "Te Whariki." An ever-growing base of research and literature is available about the working theories children hold and ways that teachers might support working theory development. In this article, I draw on…

This paper attempts to address challenges identified by Michael Young and those arising from his writings on 'powerful knowledge' to gain a deeper insight into the relationship between everyday horizontal knowledge and disciplinary vertical knowledge as well as how we can approach it in a way that benefits pedagogy. The attempt includes the move…

In this article, we integrate two constructionist approaches--the theory of constructed emotion and rational constructivism--to introduce several novel hypotheses for understanding emotional development. We first discuss the hypothesis that emotion categories are abstract and conceptual, whose instances share a goal-based function in a particular…

Emotion development research centrally concerns capacities to produce emotions and to think about them. We distinguish these enterprises and consider a novel account of how they might be related. On one recent account, the capacity to have emotions of various kinds comes by way of the acquisition of emotion concepts. This account relies on a…

In Study 1, 103 children ages 4 through 10 answered questions about their concept of and belief in luck, and completed a story task assessing their use of luck as an explanation for events. The interview captured a curvilinear trajectory of children's belief in luck from tentative belief at age 4 to full belief at age 6, weakening belief at age 8,…

I consider three aspects of children's thinking about religious phenomena. It displays intriguing parallels with their thinking about scientific phenomena; it has an impact on their moral behavior; and it is likely to impact their religious experience. Children's gradual conceptual progress in the domain of religion resembles their conceptual…

The recent proliferation of research on children's supernatural concepts is noteworthy, as this work is necessary for a full account of human cognition. Despite this advancement in our field, there is a lingering tendency for scholars to exotify supernatural concepts; to treat them as distinct or special. Arguments have been raised that these…

Generating own examples for previously encountered new concepts is a common and highly effective learning activity, at least when the examples are of high quality. Unfortunately, however, students are not able to accurately evaluate the quality of their own examples and instructional support measures such as idea unit standards that have been…

Formal climate education without consideration of the ocean is incomplete. The effectiveness of a new climate lesson for youth that includes the ocean-climate nexus was examined by delivering the lesson to nine classes situated in separate British Columbia, Canada public schools and assessing the students' understanding of basic climate concepts…
