Multidimensionality and hierarchical data structure are common in assessment data. These design features, if not accounted for, can threaten the validity of the results and inferences generated from factor analysis, a method frequently employed to assess test dimensionality. In this article, we describe and demonstrate the application of the…

Psychology originally defined parent-child conflict in terms of interpersonal relationships, where parent-child conflict is a process of inconsistent attitudes between parents and children that occurs in a family setting. For this end, we aims to investigate the influence of parental awareness on preschoolers' perception of parent-child conflict…

There is a need for robust evidence about which educational interventions work in preschool to foster children's cognitive and socio-emotional learning (SEL) outcomes. Lab-based individually randomized experiments can develop and refine such interventions, and field-based randomized experiments (e.g., cluster randomized trials) evaluate their…

Infants exhibit visual preferences for gender-typed objects (e.g., dolls, toy vehicles) that parallel the gender-typed play preferences of preschool-aged children, but the developmental stability of individual differences in early emerging gender-typed preferences has not yet been characterized. In the present study, we examined the longitudinal…

This study is the first to systematically investigate the influence of child gender and age, on parents' perceptions of UK children's digital media use at home. It provides an in-depth exploration of how children's age and gender influence the balance between children's use of digital and non-digital media at home. The data draw on 709 parents'…

Proper segmentation of auditory streams is essential for understanding music. Many cues, including meter, melodic contour, and harmony, influence adults' perception of musical phrase boundaries. To date, no studies have examined young children's musical grouping in a production task. We used a musical self-pacing method to investigate (1) whether…

The study of executive function (EF) has become increasingly popular in multiple areas of research. A wealth of evidence has supported the value of EF in shaping notable outcomes across typical and atypical development; however, little evidence has supported the cognitive contributors to early EF development. The current study used data from a…

Alleviating disadvantage in low-income environments predicts higher cognitive abilities during early childhood. It is less established whether family income continues to predict cognitive growth in later childhood or whether there may even be bidirectional dynamics. Notably, living in poverty may moderate income-cognition dynamics. In this study,…

Children's fine motor skills (FMS) are being increasingly recognized as an important aspect of preschool development; yet, we know very little about the experiences that foster their development. We utilized a parent-administered children's fine and gross motor activities questionnaire (MAQ) to investigate links with FMS. We recruited a sample of…

This study looked at the relationship between participation in a structured sports program and gross-motor-skills development in children aged 3 to 6 years. Twenty-seven children participated in the study, with 16 children receiving an eight-week sports program intervention. Children were assessed at pre- and postintervention using a modified…

Bilingual preschoolers often perform better than monolingual children on false-belief understanding. It has been hypothesized that this is due to their enhanced executive function skills, although this relationship has rarely been tested or supported. The current longitudinal study tested whether metalinguistic awareness was responsible for this…

Economic inequities are common in low and middle-income countries (LMIC), and are associated with poor growth and development among young children. The objectives are to examine whether maternal education and home environment quality: 1) protect children by attenuating the association between economic inequities and children's growth and…

In many decision situations, individuals must actively search information before they can make a satisfying choice. In such instances, individuals must be aware of the fact that not all information may be equally relevant for the choice at hand--thus, individuals should weight information by its respective relevance. We compared children's and…

The capacity to plan ahead and provide the means for future ends is an important part of human practical reasoning. When this capacity develops in ontogeny is the matter of an ongoing debate. In this study, 4- and 5-year-olds performed a future planning task in which they had to create the means (a picture of a particular object, e.g., a banana)…

Children younger than three years old are able to detect hidden rules in numerical sequences, and this ability matches that of adults by age seven. However, the developmental trajectory of this ability during the ages of four to six remains unknown. The present study adopted a modified Brixton task to address this issue. In this task, children…
