Chimpanzees and other great apes seem to be much less cooperative than humans overall, yet they nevertheless reliably help others in many instrumental circumstances. Although in many contexts the helping behavior of chimpanzees is quite similar to that of human children, recent studies using both behavioral and psychophysiological paradigms have…

Compare developmental profiles and core ASD symptom manifestation between male and female toddlers with DSM-5 ASD. Retrospective record review of 500 toddlers (79% male) at time of ASD diagnosis. There were no differences in developmental functioning between males and females. When adjusting for multiple comparisons, sex differences were only…

The current study conducted a comparative analysis of the effects of select components of Parent-Child Interaction Therapy, labeled praise, behavior descriptions, and reflections on child vocalizations in two children with autism spectrum disorder and accompanying language delays using a concurrent multiple baseline across participants design. The…

Many children with autism spectrum disorder experience feeding difficulties that can lead to increased health risks (e.g., severe nutrition deficiencies, obesity-related illnesses) if left untreated. Intensive feeding programs that use behavior-analytic interventions have reported positive outcomes for treating challenging behavior associated with…

Participation in Organised Extracurricular Social Activities (OESA) can provide positive outcomes for children. This study investigated whether children aged 4 to 12 years diagnosed with autism differ in their OESA participation and experience compared to neurotypical peers. Parents of autistic children (n = 35) and those of neurotypical peers (n…

Previous research has documented that children count spatiotemporally-distinct partial objects as if they were whole objects. This behavior extends beyond counting to inclusion of partial objects in assessment and comparisons of quantities. Multiple accounts of this performance have been proposed: children and adults differ qualitatively in their…

Logistic regression was used to examine the use of Autism Spectrum diagnostic categories from pre-COVID-19 in-person evaluations and COVID-19 telehealth evaluations at a specialist community mental health clinic. The diagnostic classification for children 0-5 (DC: 0-5) affords a wider range of diagnoses that allowed for inferences of clinician…

Research Findings: Early childhood is a critical period for the development of eating behaviors and novel approaches are needed to promote healthy food acceptance among preschoolers. This pilot study examined the feasibility and preliminary effectiveness of a 6-week mindful eating and yoga intervention targeting children's self-regulation of…

Most extant research on parental socialization for child appreciation has either conflated appreciation and gratitude or fallen foul of a conceptual-operational mismatch, yielding theoretical controversies and inconsistent results. Using a matched conceptualization and operationalization of appreciation and based on three waves of data from 496…

Objective: The study aims to examine family functionality, emotion regulation difficulties, preference for loneliness, social exclusion, internalizing and externalizing disorders, and executive functions in children with Attention Deficit Hyperactivity Disorder (ADHD) and Cognitive Disengagement Syndrome (CDS) and compare with ADHD, and ADHD+…

Social emotional learning (SEL) programs have been found to be effective on multiple outcomes, but few empirical studies were conducted in the Chinese context. The present study aimed to develop a Chinese SEL program for elementary school students, examine its effects on students' social emotional skills and mental health, and explore which groups…

Children exhibit a self-relevance effect whereby they share more candies with close friends and acquaintances than with strangers. The present study aimed to reduce the negative consequences of self-relevance effects by enhancing the behavioural control of sharing behaviour. This study initiated two behavioural control levels to investigate…

This study investigated the effect of a mindfulness-based intervention on pathological symptoms in boys with externalised disorders. A total of 24 elementary school students with externalising disorders, diagnosed by completing the Child Behavior Checklist (CBCL), were randomly assigned to a mindfulness-based intervention for two months. One…

Prior research has shown that social-emotional learning (SEL) interventions offer promise for supporting young children's outcomes, but implementation problems are frequent, especially in low-resource contexts. This study describes the adaptation and efficacy of a new, classroom-based SEL intervention for children aged 3 to 6 years in early…

Previous research on 4-6-year-olds' interpretations of adjunct control has observed non-adult-like behavior for sentences like "John called Mary before running to the store." Several studies have aimed to identify a grammatical source of children's errors. This study tests the predictions of grammatical and extragrammatical accounts by…
