Visual illusions provide a means of investigating the rules and principles through which approximate number representations are formed. Here, we investigated the developmental trajectory of an important numerical illusion--"the connectedness illusion," wherein connecting pairs of items with thin lines reduces perceived number without…

Design thinking is a cognitive, iterative process that involves identifying goals, understanding users, and creating solutions. It has changed from a designers' activity to an all-around approach to the innovation process and become a pedagogical phenomenon. In this article, design thinking method is studied in an educational context among young…

This paper contains an analysis of some early thinking of 94 young children aged 5 years 7 months to 6 years 5 months. These children were interviewed as part of a larger study of the multiplicative thinking of children who were midway through their first year of school in Australia. They had not been formally taught multiplication or division at…

As adults, we do not expect ignorant agents to behave randomly or always get things wrong. Instead, we expect them to act reasonably, guided by past experiences. We test whether 4-to-6-year-olds share this intuition and use it to infer others' knowledge, or whether they rely on a simple "ignorance = error" heuristic identified in past…

Self-regulation--the monitoring and control of thoughts, feelings, and behavior--plays a central role in guiding healthy social development. While the bulk of the literature examining children's self-regulation has focused on how much or how well children can regulate specific cognitive functions or behaviors (e.g., emotion control, delay of…

Examining emotion recognition and response to music can isolate recognition of and resonance with emotion from the confounding effects of other social cues (e.g., faces). In a within-sample design, participants aged 5-6 years in the eastern region of the United States (N = 135, M[subscript age] = 5.98, SD[subscript age] = 0.54; 78 female, 56 male;…

Children's foundational mathematical skills are critical for future academic attainment. While home mathematical activities (HMAs) have been proposed to support these skills, the extent to which engaging in them supports mathematical skills remains unclear. This preregistered systematic review and multilevel meta-analysis identified 351 effect…

Previous researchers have demonstrated that using stimuli identified via daily brief preference assessments may produce more responding under concurrent-schedule arrangements than using stimuli identified via lengthy, pre-treatment preference assessments (DeLeon et al., 2001). To date, this has not been evaluated within the context of skill…

This study seeks to enrich our understanding of modeling-based learning (MbL) in kindergarten science education, investigating the influences of different modeling tools on kindergarten child-constructed models and their modeling reasoning. Therefore, this multi-case study aimed at providing in-depth descriptions of how MbL was enacted by 66…

Knowing a child's affiliative feelings about a peer helps us understand child's social behavior toward peers and can predict how a relationship between two children would continue. A picture-drawing task, in which a child draws himself or herself and a peer, is a potentially valid way to measure a child's feelings of affiliation toward the peer.…

The purpose of this study was to examine the effects of differential reinforcement of other behavior (DRO) on reducing unsafe playground behavior of young children at school and subsequently, if necessary, the additive effects of a brief time-out. The DRO procedure was effective in eliminating unsafe behavior for one of four participants. The…

Questioning the common practice of treating texts as property that can be stolen and instead exploring the social and rhetorical dimensions that define what is owned (and what is not), as well as what can be taken and appropriated, I drew on data from a yearlong qualitative investigation of young children writing with technology to interrogate how…

A key milestone in the development of fairness is "disadvantageous inequity aversion": a willingness to sacrifice valuable rewards to avoid receiving less than a peer. The equal respect hypothesis suggests that, in addition to material concerns, children are also motivated to reject disadvantageous inequity due to interpersonal concerns.…

The aim of this study was to develop caregiver-friendly recipes for thickened liquids consistent with the International Dysphagia Diet Standardisation Initiative (IDDSI) guidelines using noncommercial thickening agents to reduce variability in preparation. Recipes were tested combining base and thickening agents, where base agents were measured in…

Autism spectrum disorders are potentially associated with gastrointestinal dysfunction, although the underlying mechanisms remain unclear. Recently, the oral cavity has gained attention as the starting point of the digestive tract. We aim to explore the potential association between altered oral microbiota and oxidative stress in individuals with…
