Children's understanding of the stability of gender over time has long been recognized as a hallmark of early childhood cognitive development. Prior research has argued that until roughly age 6, children do not understand that a person's gender identity remains consistent if the person undergoes a change in gendered behavior or appearance.…

Sometimes we should persist to succeed. But other times it might be wiser to give up on the task at hand and focus our energy on something new. Knowing whether a task is worth the effort potentially requires multiple capacities, including sensitivity to one's own likelihood to succeed on the current problem, the associated costs with continuing to…

The study aimed to examine the difference between cheating and persistence during a persistence task to advance persistence measurement. Through a within-subject design (N = 78, mean age: 5.2 years), two different versions of the puzzle box task were administered. The original puzzle box task was administered in condition I (i.e., open version).…

Pretend play is an important, universal activity of early childhood, but research to date contains multiple inconsistencies in definitions and measurement of pretend play. To begin to resolve this issue, we conducted a first study of the multiple different behaviors of pretend play in the preschool years (3-5 years), and investigated their…

The development of children's future-oriented cognition has become a popular research topic in the past two decades. Much of this research focuses on the preschool and middle childhood years, but very little is known about the future-oriented cognitive abilities of toddlers and young preschoolers. The present study investigated the emergence of…

Between the ages of 3 and 5, children develop greater control over attention to visual dimensions. Children develop the ability to flexibly shift between visual dimensions and to selectively process specific dimensions of an object. Previous proposals have suggested that selective and flexible attention is developmentally related to one another.…

The current study examined children's spontaneous private speech during the vertical and the horizontal Tube Task to shed light on the cognitive, motivational, and emotional processes underlying tool innovation. Tool innovation is defined as solving a novel problem by using or modifying objects in a new and useful way without prior instructions.…

A live video was used to study the development of visual self-recognition in a cross-sectional sample of 152 typically developing French children aged between 15 months to 6 years. Three reactions to a mark placed on the child's cheek without their knowledge were studied: the touch of the mark with their hand, the ocular responsiveness to the mark…

Block-building skills at age 3 are related to spatial skills at age 5 and spatial skills in grade school are linked to later success in science, technology, engineering, and mathematics (STEM) fields. Though studies have focused on block-building behaviors and design complexity, few have examined these variables in relation to future spatial and…

The aim of the present study was to explore how maternal reminiscing relates to socioemotional development during middle childhood. Specifically, analyses explored the link between maternal reminiscing and children's internalizing (emotional problems and peer problems), externalizing (hyperactivity and conduct problems) and prosocial behavior…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

Identifying correlates of aggressive behavior in children might help to find potential candidates for interventions in aggression reduction. While some previous studies found that children's Theory of Mind (ToM) and inhibitory control (IC) correlate with aggressive behavior, others did not confirm this relation. One explanation for these mixed…

Spatial play in early childhood is associated with a variety of spatial and cognitive skills. However, these associations are often derived from studies in which different tasks are used across different age ranges, leaving open the question of how children's natural behaviors during spatial play develop from infancy into the early preschool…

Temperamental effortful control (EC) and executive functions (EF) are two frameworks for studying self-regulation in children. Despite stemming from different research traditions, they show many conceptual and theoretical similarities and their corresponding tasks are often used interchangeably. However, little is known about how and whether the…

Pretend play is common in childhood. Yet by age 4, children shown pretend and real activities in a book said they would choose to do the real activity over the pretend one. The present studies extended this research, examining children's actual behavior in laboratory and school settings (Study 1, n = 32, M = 59.32 months; and Study 2, n = 16, M…
