There is now wide consensus that the quality of family relationships is involved in the development of child executive functioning (EF), a set of cognitive skills that bear critical importance for social and academic adjustment at school. This body of research has, however, focused almost exclusively on dyadic parent-child interactions and failed…

It has been debated whether the progressive emergence of theory of mind (ToM) in autistic children is compatible with a "delayed" or "different" development model, and whether and how the sequential consolidation of ToM concepts is subject to cross-cultural variations in autistic and typically developing (TD) children. To study…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

Although metacognition is considered a central aspect of self-regulated learning and is often linked to learning outcomes, little is known about the intraindividual development and factors that lead to developmental improvement over time. This longitudinal study investigated 2nd graders' (N = 119, aged 8-9 years) metacognitive monitoring and…

The development of (early) numerical cognition builds on children's ability to understand and manipulate quantities and numbers. However, previous research did not find conclusive evidence on the role of symbolic and non-symbolic skills in the development of (early) numerical cognition. The aim of the current study was to clarify the relation…

Evidence points to the possibility of promoting executive functions (EF) through school interventions. Little is known, however, about the effectiveness of this type of intervention in situations of social vulnerability. This study investigated the effectiveness of an EF intervention program applied with a sample of preschool children, in a…

Question asking plays a fundamental role in learning, and the cognitive development literature contains many studies of specific types of question-asking skills. However, little is known about the developmental course across different aspects of question asking, of which we explore: (a) the ability to ask questions that enable children to solve a…

The Test of Emotion Comprehension (TEC) has been used extensively to investigate children's understanding of emotion. The present study aimed at investigating the TEC's factorial structure, its measurement invariance across age and gender, and defining age-referred TEC scores, in a large sample of 1,478 children (755 males, 723 females) aged…

Two studies investigated young 2- and 3-year-old Turkish children's developing understanding of normativity and freedom to act in games. As expected, children, especially 3-year-olds, protested more when there was a norm violation than when there was none. Surprisingly, however, no decrease in normative protest was observed even when the actor…

Parent-child reminiscing talk about positive and negative events provides children with unique opportunities to develop emotion competence. Very little work has involved families from low-income households and ethnically diverse backgrounds. We examined: 1) event valence (positive vs. negative) and ethnic differences in mother-child reminiscing…

Although high-quality early educational environments are thought to be related to the growth of children's skills in mathematics, relatively little is known about specific aspects of classroom instruction that may promote these abilities. Data from a longitudinal investigation were used to investigate associations between teachers' language while…

Summer slide, uneven growth of academic skills during the calendar year, captures the fact that the learning gains children make during the school year do not continue at the same pace over the summer, when children are typically not in school. We compared growth of reading skills during the school year and during the summer months in children…

Reading-specific and general color-shape cognitive flexibility were assessed in 68 first and second graders to examine: 1) the development of graphophonological-semantic cognitive flexibility (the ability to process concurrently phonological and semantic aspects of print) in comparison to color-shape cognitive flexibility, 2) the contribution of…
