Research Findings: In addition to being a regulatory strategy, children's private speech may enhance or interfere with their effortful control used to regulate emotion. The goal of the current study was to investigate whether children's private speech during a selective attention task moderated the relations of their effortful control to their…

A simulation study that used 3,000 computer-generated event streams with known behavior rates, interval durations, and session durations was conducted to test whether the main and interaction effects of true rate and interval duration affect the error level of uncorrected and Poisson-transformed (i.e., "corrected") count as estimated by…

Whereas some evidence suggests that toddlers consider targets' deservingness when deciding whom to help, other research demonstrates that toddlers help indiscriminately. The present findings shed light on this discrepancy by demonstrating that although toddlers do exhibit selectivity in giving behaviors, their emotional responses are comparatively…

The weaning period, in which complementary foods are introduced into the infant's diet, can be challenging, with dislike of novel foods known to be common. However, even though at six months (the current recommended age for the introduction of complementary foods) most infants are able to feed themselves with graspable pieces of food, the majority…

Purpose: The focus of scientific research on the parental well-being has been mainly placed on parents of pre-school children. However, recent findings indicated that parents of pre-school children show lower levels of depression and higher levels of self-efficacy and self-esteem, compared to parents of older children. The purpose of this paper is…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

Background: Informant discrepancies between mother and child have challenged the assessment, classification, and treatment of childhood anxiety. Despite numerous studies on this matter, the implications and consequences for research and clinical practice remain unclear. Objective: The present study aimed to obtain meaningful clinical information…

Children (n = 202; 4 to 7 years old) witnessed a confederate break a toy and were asked to keep the transgression a secret. Children were randomly assigned to a Coaching condition (i.e., No Coaching, Light Coaching, or Heavy Coaching) and a Moral Story condition (i.e., Positive or Neutral). Overall, 89.7% of children lied about the broken toy when…

Educators face an ever-increasing challenge of addressing the impact of childhood trauma in the classroom. Children impacted by trauma experience a lack of ability to regulate their behavior and learn, and most school staff have little professional development on this topic and how to best address it in the classroom. The purpose of this study was…

Data were collected about 95 fourth-grade and fifth-grade children from three sources (teachers, parents, and children) on four constructs related to aggression (proactive aggression, reactive aggression, callous-unemotional traits, and anger dysregulation) by using a multitrait-multimethod design. Two goals were addressed through a…

This study investigates demographic and clinical factors associated with initiation, continuation, and adherence to behavioral health treatment (BHT) among children with autism spectrum disorder. Among 293 insured children referred for applied behavior analysis (ABA) based BHT, 23% never initiated treatment. Among those initiating treatment, 31%…

In this study, the relationship between play, language skills and social competence is explored in a sample (n = 1005) of 33-month-old toddlers in a Norwegian early childhood education setting--Barnehages--based on two observational materials ("Tras" and "Alle med"). The study has two aims: (1) to investigate whether there is a…

This study explored the impact of parental sleep quality on the experience of behavior problems by children with autism spectrum disorder. A 14-day daily diary was used in a sample of 176 mother-father couples. Dyadic multilevel models were conducted to examine the between-person and within-person effects of previous-night sleep quality on…

One of the deficits observed in autism spectrum disorder (ASD) is impaired imaginative play. One form of imaginative play common in many typically developing (TD) children is having an imaginary companion (IC). The occurrence of ICs has not been investigated extensively in children with ASD. We examined differences in parent report of IC between…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…
