A wealth of developmental research suggests that preschoolers are capable of reporting, imitating, and performing sequential actions they engage in routinely. However, few studies have explored the developmental and cognitive mechanisms required for learning how to perform such routines. A previous computational model of routines argued that a…

Background: Effective health education fosters lifelong well-being, but traditional educator-centered methods in Morocco may limit student engagement and comprehension. Understanding educator-student communication is key to designing early interventions that enhance learning. Methods: This exploratory quantitative study analyzed health education…

It is often argued that metacognition includes 2 components: monitoring and control. However, it is unclear whether these components can operate independently, or whether they always operate as part of a hierarchy. The current study attempts to address this issue. In Experiment 1 (N = 90), age-related differences were assessed to examine the…

The aim of this study is to determine school readiness of primary school students in mixed-age classrooms. The sample of this study, using embedded mixed method design, consists of 909 first grade students in primary school and 30 primary school teachers determined by stratified purposeful sampling method. In this study, "Primary School…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

The present study aims to understand children's behavior within classroom settings in terms of conditioning theories. It was designed based on grounded theory. Data were collected through participant observation and 98 children whose ages varied between 6 and 10 years were observed. Data were inductively analyzed. Findings indicated that…

Prior research suggests that human children lack an aptitude for tool innovation. However, children's tool making must be explored across a broader range of tasks and across diverse cultural contexts before we can conclude that they are genuinely poor tool innovators. To this end, we investigated children's ability to independently construct 3 new…

One of the lawlike regularities of psychological science is that of developmental progression--an increase in sensorimotor, cognitive, and social functioning from childhood to adulthood. Here, we report a rare violation of this law, a developmental reversal in attention. In Experiment 1, 4­- to 5­- year ­olds (n = 34) and adults (n = 35) performed…

Atypical motor development has frequently been reported in infants at elevated likelihood for autism spectrum disorder. However, no previous study has used detailed motion capture technology to compare infant siblings of children with autism spectrum disorder and infant siblings with no familial history of autism spectrum disorder. We investigated…

This article assessed changes in the association between single motherhood and children's verbal cognitive ability at age-11 using data from three cohorts of British children, born in 1958 (n = 10,675), 1970 (n = 8,933) and 2000 (n = 9,989), and mediation analysis. Consistent with previous studies, direct effects were small and insignificant. For…

Representations of social categories help us make sense of the social world, supporting predictions and explanations about groups and individuals. In an experiment with 156 participants, we explore whether children and adults are able to understand category-property associations (such as the association between "girls" and "liking…

This study examined how 5- and 9-year-old children (N = 40) produce pantomimes of object use on verbal request. The task required participants to enact an action with an imagined object. Results showed that with age, children (a) proceeded from body part as object to imaginary object and (b) incorporated into their pantomimes more distinctive…

Differentiation of intelligence refers to changes in the structure of intelligence that depend on individuals' level of general cognitive ability (ability differentiation hypothesis) or age (developmental differentiation hypothesis). The present article aimed to investigate ability differentiation, developmental differentiation, and their…

A pretest-training-posttest design assessed whether training to improve spatial skills also improved mathematics performance in elementary-aged children. First grade students (mean age = 7 years, n = 134) and sixth grade students (mean age = 12 years, n = 124) completed training in 1 of 2 spatial skills-spatial visualization or form…
