Developing algebraic thinking is a key factor in learning mathematics. Despite its importance, many students still struggle with algebraic concepts. This research investigates students' achievements in algebraic thinking using Demetriou's test across 7th (approximately 12-13 years old), 8th (approximately 13-14 years old), and 9th (approximately…

In the adult brain, biases in the allocation of spatial attention can be measured using a line bisection task and are directly relatable to neural attention signals in the fronto-parietal attention network. Behavioral studies on the development of spatial biases have yielded a host of inconsistent results, likely due to variance in sample size,…

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived…

Objective: This study aimed to investigate the current status of cognitive development and central auditory processing development of preschool children with minimal and mild hearing loss (MMHL) in Nanjing, China. Method: We recruited 34 children with MMHL and 45 children with normal hearing (NH). They completed a series of tests, including…

The basolateral complex of amygdala (BLA) processes emotionally arousing aversive and rewarding experiences. The BLA is critical for acquisition and storage of threat-based memories and the modulation of the consolidation of arousing explicit memories, that is, the memories that are encoded and stored by the medial temporal lobe. In addition, in…

In four experiments, we investigate how the ability to detect irrelevant explanations develops. In Experiments 1 and 2, 4- to 8-year-olds and adults rated different types of explanations about "what makes cars go" individually, in the absence of a direct contrast. Each explanation was true and relevant (e.g., "Cars have engines that…

When reasoning about a representation (e.g., a toy lion), children often engage in "iconic realism," whereby representations are reported to have properties of their real-life referents. The present studies examined an inverse difficulty that we dub "representational disregard": overlooking (i.e., disregarding) a…

Cognitive control can be triggered by explicit or implicit events; it has been proposed that these two possibilities tap into dissociable mechanisms. In this study, we investigate this idea by testing whether young children, who struggle with explicitly triggered control, can demonstrate proportion congruency effects--which are based on implicit…

This article offers insights into trends found in 74 empirical studies on teaching and learning a foreign language (FL) in pre-primary schools in 25 countries. The emerging picture is like that of primary-school programs: most are implemented in English, mostly owing to parents' enthusiasm rather than evidence on long term FL benefits. Researchers…

Working memory and recognition memory develop across adolescence, but the relationship between them is not fully understood. We investigated associations between n-back task performance and subsequent recognition memory in a community sample (8-30 yr, n = 150) using tasks from the Adolescent Brain Cognitive Development Study (ABCD Study) to…

The association between parents' work-family conflicts and children's academic outcomes is an understudied topic. The present research investigates the role of quadratic measures--parental working hours' scale, parental age, parental interaction quality, and learning materials at home--in children's cognitive outcomes. It employs a community…

While working memory (WM) is a powerful predictor for children's school outcomes, autistic children are more likely to experience delays. This study compared autistic children and their neurotypical peers' WM development over their elementary school years, including relative growth and period of plasticity. Using a nationally-representative…

We investigated the effect of cognitive training of executive functions on children's cognitive outcomes. To address this issue, a systematic meta-analysis of published research articles on cognitive training interventions was performed considering children's age, training duration, -procedure, and -technology in moderator analyses. The results (N…

The present cross-sectional study examined some of the factors associated with psychological distress among students enrolled in Bachelor's and Master's programs. We investigated the roles of age, academic performance, creativity, cognitive flexibility, educational mattering, and anti-mattering and their roles when discussing participants'…

When faced with entities with potentially ambiguous category membership, adult category judgments are strongly biased toward dangerous and distinctive properties. For example, a cyanide-water mixture is categorized as cyanide. We used a developmental approach to better understand this cross-domain effect, which we term the asymmetric…
