Purpose: To investigate serum levels of VEGF, IGF-1 and FGF-2, and relationships with several clinical characteristics in children and adolescents with autism spectrum disorder (ASD) with and without bipolar disorder (BD). Method: 40 subjects with ASD + BD as study group, and 40 subjects with ASD as control group were included. Serum levels of…

Purpose: An official autism diagnosis is required to access timely intervention and is associated with better long-term wellbeing and mental health. Certain demographic characteristics, such as being female or a racially or ethnically minoritized youth, have been associated with significant diagnostic lag. However, it remains unclear how assigned…

Despite its centrality within the Convention on the Rights of the Child, teachers' behaviors promoting progressive autonomy, the psychological processes involved in their implementation and their consequences for teachers' well-being has been neglected. Two studies assess early childhood teachers' promoting progressive autonomy behaviors and their…

Respiratory Sinus Arrhythmia Reactivity (RSA-R) correlates both positively and negatively with externalizing behaviour in autistic individuals. These inconsistencies may result from task-based differences. This pilot study measured RSA-R in 4-to 6-year-olds, across two timepoints, using four validated tasks with matched baseline and challenge…

This study investigated the potential influences of administration context on the measurement of child skills. The Brief Observation of Social-Communication Change (BOSCC) was administered at two time points to preschool-aged children with autism in two contexts: (1) at school by trained research staff and (2) at home by the parent. Participants…

Children can only develop spoken language through consistent exposure to the acoustic cues that comprise speech and language. Until recently, hearing levels from the clinical audiogram were the primary measure used to define typical hearing and the presence or degree of a child's hearing loss. While the clinical audiogram remains an important…

During their early years, children with autism may not meet the same communication and language milestones as their peers (Wodka et al., 2013). Many children with autism experience language delays and may rely on one-word or phrase speech, rather than using grammatically fluent speech (Anderson et al., 2007; Wodka et al., 2013) that is often…

The purpose of this study was to examine the associations of outdoor playtime, screen time, and sleep duration with ball bouncing skills in a sample of 3- to 5-year-old children. Participants were young children (N = 11,121; 48.8% female) whose parent/guardian completed the 2022 National Survey of Children's Health. The dependent variable was one…

The first years of life are an optimal time for developing motor competence. However, the evidence regarding motor competence in early childhood is fragmented and needs to be clearly synthesized and presented. To establish effective evidence-based decision making in research, practice, and policy for the early years, this expert statement, on…

The learning and social development benefits associated with pupils collaborating in small groups have been well documented over recent decades; however, research exploring personality as a mediating factor in small group learning is sparse. In this study we identified pupils who self-reported low levels of extraversion and/or high levels of…

Within ethnolinguistic minority families, parents and children often differ in language usage and proficiencies. In this study, we investigate the role of intergenerational language differences in cultivating and/or complicating family relations and how aspects of gender may moderate these relationships. Guided by the Family Language Policy…

On average, deaf and hard-of-hearing (DHH) children have difficulty developing expressive spoken vocabulary comparable to hearing peers. Yet, there are no evidence-based practices to guide classroom instruction for teachers of the deaf. Retrieval practice--a robust learning strategy--has been shown to improve children's retention of vocabulary,…

This study investigated the impact of language sample length on mean length of utterance (MLU) and aimed to determine the minimum number of utterances required for a reliable MLU. Conversations were collected from Mandarin-speaking, hard-of-hearing and typical-hearing children aged 16-81 months. The MLUs were calculated using sample sizes ranging…

This paper studies the association between caregiver--child interactions and early childhood development in literacy and numeracy in West and Central Africa. Data comes from Multiple Cluster Indicator Surveys (MICS) conducted in Central African Republic, Chad, Democratic Republic of the Congo, Gambia, Ghana, Guinea-Bissau, Sierra Leone, and Togo…

In recent years, the theoretical lens of new materialism(s) and surge in feminist thinking has opened up new ways of understanding the complexities of motherhood, babyhood and early childhood. This surge in post-qualitative and feminist inquiry towards the troubling of dominant early childhood abstractions and norms, as well as resistance to…
