We investigated the role of distinct inhibitory processes as 4- to 6-year-olds from the Northeastern United States (N = 48, M[subscript age] = 68.27 months, 22 boys, 26 girls; 63% White, 6% Black, 4% Asian, 2% Hispanic, 8% more than one race, with 17% not reporting) and adults evaluated accurate or deceptive information from human or non-human…

The current research examined how seeking versus receiving help affected children's memory and confidence decisions. Baseline performance, when no help was available, was compared to performance when help could be sought (Experiment 1: N = 83, 41 females) or was provided (Experiment 2: N = 84, 44 females) in a sample of predominately White 5-, 7-,…

Despite its importance, studies involving developmental delay remain low in the last 10 years in Latin. The objective of the present study was to estimate and compare the prevalence of developmental delay during 2019-2022 in Mexican children under 5 years of age. This was a cross-sectional study carried out in Nuevo Leon, Mexico (n = 2,951).…

The purpose of this systematic review was to examine the influence of relative age effect (RAE) on motor competences (MC) and physical fitness (PF) of preschool children. The search was conducted through three different databases: Web of Science, Scopus and EBSCO up to 11 August 2023. This study was conducted and reported according to the PRISMA…

There is evidence that mastery motivation contributes to developmental outcomes, both for typically developing individuals and for those with disabilities such as Down syndrome. Mastery motivation appears to be a stable trait, at least during early childhood, but research with adults has been restricted by the absence of an appropriate measure.…

Children (N = 103, 4-9 years, 59 females, 84% White, c. 2019) completed visual processing, visual feature integration (color, luminance, motion), and visual search tasks. Contrast sensitivity and feature search improved with age similarly for luminance and color-defined targets. Incidental feature integration improved more with age for…

Few studies on the development of forgiveness involved young children and adolescents, and very few involved samples from non-western countries. This study focused on the development of willingness to forgive a particular transgression in participants aged 4 to 12 years and from two different cultures: a South African culture (Mozambique) and a…

The potential influences on children's sharing decision caused by birth order and sibling age gap were examined. A third-party resource allocation task was adopted to examine five- to six-year-old children's sharing decision when they expected a protagonist to allocate resources between two recipients with different social relationships. Children…

Humans appear to intuitively grasp definitions foundational to formal geometry, like definitions that describe points as infinitely small and lines as infinitely long. Nevertheless, previous studies exploring human's intuitive natural geometry have consistently focused on geometric principles in planar Euclidean contexts and thus may not…

People who are in close relationships tend to do and like the same things, a phenomenon termed the "homophily principle." The present research probed for evidence of the homophily principle in 4- to 6-year-old children. Across two experiments, participants (N = 327; 166 girls, 161 boys; located in the Midwestern United States) were asked…

Gender-stereotyped beliefs develop early in childhood and are thought to increase with age based on prior research that was primarily carried out in Western cultures. Little research, however, has examined cross-cultural (in)consistencies in the developmental trajectory of gender-stereotyped beliefs. The present study examined implicit gender-toy…

Objectives: The primary aim was to investigate the variability in language development in children aged 5-7.5 years after bilateral cochlear implantation (CI) up to the age of 2 years, and any impact of the age at implantation and additional noncognitive or anatomical disorders at implantation. Design: Data of 84 congenitally deaf children that…

The natural development of static lower limb varus/valgus alignments during early childhood is well understood. However, our understanding of dynamic lower limb frontal plane alignments is limited, and we lack normative descriptions of this phenomenon for both boys and girls. This study investigated dynamic lower limb alignment during…

Even once children can accurately remember their experiences, they nevertheless struggle to use those memories in flexible new ways--as in when drawing inferences. However, it remains an open question as to whether the developmental differences observed during both memory formation and inference itself represent a fundamental limitation on…

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…
