Delay discounting tasks measure the relation between reinforcer delay and efficacy. The present study established the association between delay discounting and classroom behavior and introduced a brief measure quantifying sensitivity to reward delays for school-aged children. Study 1 reanalyzed data collected by Reed and Martens (J Appl Behav Anal…

Preschool children naturally display competitive behavioral patterns. The purpose of the current study was to investigate the association between preschool children's regulation (regulatory and control components) and competitive behaviors (task-oriented and other-referenced). A total of 260 preschool children (47.7% girls) ranging in age from 49…

Our primary objective was to examine the extent to which moment-to-moment associations between preschool-aged children's behavior and maternal emotional support differed for mothers showing different levels of parasympathetic engagement. We used behavioral observations of maternal and child behavior and maternal changes in cardiac vagal tone…

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…

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…

The goal of the present study was to test the hypothesis that, when children respond to peer provocation assertively, their physiology at that moment will be marked by high levels of respiratory sinus arrhythmia (RSA). Participants were 35 European American (66%), African American (27%), Latino American (3%), and mixed race/ethnicity (3%) children…

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and…

Middle schoolers with or at risk for emotional and behavioral disorders (EBD) typically have a trajectory of difficult outcomes (e.g., school dropout, incarceration). Growing evidence suggests that the continuum of behavioral competence to challenges is closely linked to students' neurocognitive executive function (EF) capacities, perceived stress…

Background: Parenting strategies such as communicating clear expectations, providing calm directions, and teaching specific skills can strengthen young children's social-emotional development. Parenting programs for children with disruptive behavior often emphasize gaining compliance via effective directives, and less on how to facilitate child…

This study examined the associations of preschool children's executive function (EF) and learning behaviour (CLB) with their concurrent academic skills and the role of CLB as a mediator for the EF-academic skills link. One hundred seventy-nine children were assessed on EF and math and literacy skills. Parents and teachers completed a questionnaire…

In a preferential looking paradigm, we studied how children's looking behavior and pupillary response were modulated by the degree of phonological mismatch between the correct label of a target referent and its manipulated form. We manipulated degree of mismatch by introducing one or more featural changes to the target label. Both looking behavior…

We examined representations of attachment security using story stem narratives (Manchester Attachment Story Task, MCAST) and a family drawing task in 50 Greek children between 4 and 6 years old. Additionally, we examined the association between attachment classification based on the family drawing task and maternal reports of social and emotional…

This study had 2 primary aims: (a) to investigate the concurrent links between preschool-aged children's theory of mind (ToM) and mental state talk at 55 months and (b) to examine the longitudinal associations between preschool-aged children's social understanding, as indicated by their ToM, and mental references, and their later social competence…

The study examines the concurrent and longitudinal associations between ratings-based measures (parents, secondary caregivers, and observers) and performance-based measures of focused attention in toddlers aged 30 (n = 147), 36 (n = 127), and 42 months (n = 107). Parents and secondary caregivers rated focused attention behaviours using the…
