From the earliest moments in their lives, infants begin to build memories about their past and accumulate knowledge about the world. In this article, we focus on the distinction between memory for "specific" events and memory for "general" information, and the ongoing debate about which type of memory provides the foundation…

Aperiodic electroencephalography (EEG) activity is hypothesized to index biological mechanisms that underpin brain functioning. This longitudinal study characterized the developmental trajectories of the aperiodic slope (i.e., aperiodic exponent) and offset from infancy to 7 years of age in a US community sample (N = 391, 46.5% female,…

Unlike adults, young children think that many weird and unlikely events are impossible. Existing theories have argued that this developmental shift is driven primarily by age-related changes in knowledge as well as an increasing ability to reflect on one's modal intuitions. However, this intuition + reflection model fails to explain…

Children often say that possible events are impossible, and only gradually come to see these events as possible. For instance, they often deny that people could do unusual things, like own a pet peacock, or immoral things, like stealing or lying. These possibility denials are surprising. For instance, children have first-hand experience with the…

Conversational turns are an important predictor of cognitive and language development, but little is known about their relationship with socioemotional development. In a previous study using LENA technology, Gómez and Strasser (2021) found that conversational turns assessed with 43 infants at 18 months predicted socioemotional competencies at 30…

The aim of this study is to compare the neurological status, developmental parameters and physical fitness of children who engage in regular physical activity in the preschool period versus those who do not. The study included 305 healthy children aged 4-6 years, consisting of 154 girls and 151 boys. In addition to evaluating the demographic…

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…

Early experiences in STEM education can contribute to positive cognitive development in young children. When students have the opportunities to play, inquire, follow their interests/curiosities, develop STEM identities, be creative, and operate within concrete/contextualized STEM explorations, they will experience expansive cognitive growth.…

The following article is a thorough literature review, discussing the impact of media technology on brain development in the context of magical thinking. This systematic literature review discusses the impact of video gaming on magical thinking in early childhood. The purpose of this paper is to shed light on how media technology, especially video…

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…

Identifying the neural processes that underlie the association between children's early adverse experiences and cognitive development could inform more effective intervention strategies. The goal of the current study (data collected 2015-2021) was to examine relations among early experiences at 6 months, electroencephalography (EEG) theta power at…

For decades, developmental psychologists and educators have emphasized that learning about counterintuitive phenomena may be a critical driving force for cognitive development. Thus far, little is known about the specific content that children seek to enrich their knowledge. Using a novel book-choice paradigm, we directly examine children's…

Multidimensional theory of mind assessments should include items assessing both explicit theory of mind (theory of mind knowledge) and applied theory of mind (application of theory of mind knowledge in real-life contexts). However, the two theory of mind scores cannot be interpreted collectively to identify children having mismatched explicit and…

Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…

Several decades of research has found that early education and care can have a positive effect on children's cognitive, behavioural and social outcomes, particularly if it is of high quality, and particularly for disadvantaged children. However, less is known about the optimum number of hours, including whether this differs by socio-economic…
