Scale errors are intriguing phenomena in which a child tries to perform an object-specific action on a tiny object. Several viewpoints explaining the developmental mechanisms underlying scale errors exist; however, there is no unified account of how different factors interact and affect scale errors, and the statistical approaches used in the…

Non-rigid spatial thinking, or mental transformations where the distance between two points in an object changes (e.g., folding, breaking, bending), is required for many STEM fields but remains critically understudied. We developed and tested a non-rigid, ductile spatial skill measure based on reasoning about knots with 279 US adults (M = 30.90,…

Fundamental motor skill development is crucial in preventing preschool children from early adoption of obesogenic lifestyles. This study aims to determine the motor skill level in preschool children and its gender differences in rural of Sarawak. This was a cross sectional study with a total of 153 children from 9 kindergartens. Children in this…

Past research has shown that children's mental rotation skills are malleable and can be improved through action experience--physically rotating objects--or gesture experience--showing how objects could rotate (e.g., Frick, Ferrara, & Newcombe, 2013; Goldin-Meadow et al., 2012; Levine, Goldin-Meadow, Carlson, & Hemani-Lopez, 2018). These…

The present study explores the constructs of Chinese mothers' and fathers' engagement in toddlers' play in the daily context. A sample of 238 parents of toddlers (M = 30.43 months, SD = 3.45) completed a newly-developed instrument, the Chinese Parental Involvement in Toddler Play Activity Questionnaire (CPITPAQ), to report their play engagement.…

Although action experience has been shown to enhance the development of spatial cognition, the mechanism underlying the effects of action is still unclear. The present research examined the role of visual cues generated during action in promoting infants' mental rotation. We sought to clarify the underlying mechanism by decoupling different…

Purpose: The purpose of this article was to examine specific linkages between early visual-motor integration skills and executive function, as well as between early object manipulation skills and social behaviors in the classroom during the preschool year. Method: Ninety-two children aged 3 to 5 years old (M[subscript age] = 4.31 years) were…
