Scientists have long employed puppets in research with young children; this essay explores the validity of this practice. After considering what puppets are, their main types and history, I note the different ways puppets have been employed in research. One of these uses raises the issue of whether and when children apply their theory of mind to…

Purpose: This study examines object permanence development in infants with motor delays (MD) compared with infants with typical development (TD) and in relation to sitting skill. Methods: Fifty-six infants with MD (mean age = 10 months) and 36 with TD (mean age = 5.7 months) were assessed at baseline and then at 1.5, 3, and 6 months postbaseline.…

Purpose: This case series documents developmental changes over time and in response to a novel intervention, Sitting Together and Reaching to Play (START-Play), in children with early-life seizures. Methods: Thirteen children with early-life seizures were included from a subset of participants in the START-Play multisite, randomized controlled…

Pre-kindergarten (Pre-K) improves the school readiness of all children, but less is known about whether associations between enrollment in Pre-K and different indicators of social-emotional and executive functioning (EF) skills are sustained as children move into and across elementary school. The current study examines associations between…

Background: Children with motor delays are at increased risk for delayed means-end problem-solving (MEPS) performance. Objectives: To evaluate children with motor delays: 1) the impact of motor delay severity and MEPS mastery timing on developmental trajectories of MEPS; and 2) the effectiveness of Sitting Together And Reaching To Play…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

Purpose: This study tested whether the Sitting Together and Reaching to Play (START-Play) physical therapy intervention indirectly impacts cognition through changes in perceptual-motor skills in infants with motor delays. Methods: Participants were 50 infants with motor delays randomly assigned to START-Play plus Usual Care Early Intervention…

Objectives: Technology-based outreach offers promise for providing support to a broad population of postpartum mothers while keeping costs low. However, research on the efficacy of this approach is scarce. We conducted a pre-registered randomized pilot trial of the effects of a novel technology based approach for supporting postpartum mothers --…

This study aimed to explore whether early developmental abilities are related to future executive function (EF) in children with motor delays. Fourteen children with motor delays (Mean age = 10.76, SD = 2.55) were included from a larger study. Object interaction and developmental outcomes (Bayley-III) were evaluated at baseline and 3, 6, and 12…

Understanding others' perspectives and integrating this knowledge in social interactions is challenging for young children; even adults struggle with this skill. While young children show the capacity to understand what others can and cannot see under supportive laboratory conditions, more research is necessary to understand how children implement…

Eye movements provide a sensitive window into cognitive processing during reading. In the present study, we investigated beginning readers' longitudinal changes in temporal and spatial measures of eye movements during oral versus silent reading, the extent to which variation in eye movements is attributable to individual differences and text…

Across geographically diverse samples, engagement in stimulating activities with young children is considered an important element of parenting that promotes cognitive, behavioral, and social-emotional development. Indicators of stimulation activities are often summed, based on the assumption that more stimulation is better and that different…

Although almost everyone agrees that the environment shapes children's learning, surprisingly few studies assess in detail the specific environments that shape children's learning of specific content. The present article briefly reviews examples of how such environmental assessments have improved understanding of child development in diverse…

Although there is a rich literature on children's strategies for remembering, little attention has been paid to characterizing developmental change within individual children and to examining mediators that may bring about such change. To address these issues, we assess children's memory skills over time while simultaneously examining…

Across psychology, there is increasing recognition that the experiences of children from minoritized racial and ethnic groups are underrepresented. Research on prosocial behavior exemplifies this systemic bias. This paper suggests that measures of prosocial behavior should be revised to be more culturally equitable, in order to reflect the…
