The majority of the world's children live in low- and middle-income countries, yet the majority of early childhood cognitive research is done with a small proportion of high-income countries. These findings cannot be assumed to apply across all contexts. It is therefore necessary to confront entrenched systems of power and privilege in early…

This developmental account of executive function (EF) argues that domain-general analogical processes build a functional hierarchy of skills, which vary on a continuum of abstraction, and become increasingly differentiated over time. The paper begins by showing how a functional hierarchy can capture important aspects of EF development, including…

Executive function (EF) skills are a set of attention-regulation skills involved in intentional, goal-directed behavior that include (but are not limited to) the cool EF skills of working memory, cognitive flexibility, and inhibitory control, and also the hot EF skill of intentional reevaluation. These skills are inevitably expressed in goal- and…

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…

Although we cannot see or touch time, across many cultures, we use spatial representations to think about this abstract concept. Spatial representations of time are thought to support temporal concepts that might otherwise be difficult to represent and reason about, such as the temporal component of episodic memory. One common form of spatially…

In order for children to understand and reason about the world in an adult-like fashion, they need to learn that conceptual categories are organized in a hierarchical fashion (e.g., a dog is also an animal). While children learn from their first-hand observation of the world, social knowledge transmission via language can also play an important…

Children tend to select a novel object rather than a familiar object when asked to identify the referent of a novel label. Current accounts of this so-called "disambiguation effect" do not address whether children have a general metacognitive representation of this way of determining the reference of novel labels. In two experiments…

Striking weight biases emerge early in development, yet cognitive-developmental research has largely ignored weight as a social characteristic of interest. How do children conceive of weight? In particular, do children hold essentialist views of weight (i.e. do they view weight as natural, stable, inductively meaningful, and reflective of people's…

The relationship between motor skills and executive functions (EFs) is gaining prominence in the field of developmental psychology. However, evidence of the motor skills--EFs link in children with typical development is somewhat inconsistent and there has been no adequate attempt to evaluate it systematically across studies. In view of this, the…

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…

Children's development of executive function is a good candidate for studying cultural differences because it is a necessary capacity for becoming competent participants in cultural activities, and yet it is also likely to be shaped by culturally organized everyday experiences, with potential consequences for children's development and learning.…

Scientific reasoning refers to the thinking skills involved in conceiving and conducting an investigation. This study examined how proficiency in performing these skills develops during the upper-elementary school years. A sample of 157 children (age 7-10) took a performance-based scientific reasoning test in three consecutive years. Four distinct…

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…

A growing body of literature has established longitudinal associations between key social cognitive capacities emerging in infancy and children's subsequent theory of mind. However, existing work is limited by modest sample sizes, narrow infant measures, and theory of mind assessments with restricted variability and generalizability. The current…

Standard Australian reading assessment tests are criticized for being culturally inappropriate for use with Australian Indigenous children, particularly for those living in remote and very remote regions, as these tests are culturally biased towards mainstream Australian culture and imperceptive to Indigenous knowledge, language, concepts, and…
