Altered drive to socially engage is a transdiagnostic feature across multiple psychopathologies. Yet, lack of clarity regarding specific processes that constitute social drive, along with insufficient measurement methods, has hindered understanding in this area. This study ascertained the feasibility of approximating difficulties within specific fine-grained social drive processes as proposed by 2 theoretical frameworks: “orienting,” “wanting,” “pursuing,” “liking,” “learning,” and “reticence” within a reward processing framework and “orienting,” “seeking and maintaining,” and “liking” within a social motivation framework.

Autism spectrum disorder (ASD), a neurodevelopmental condition characterised by social and communication differences, is complex and aetiologically heterogeneous. Untargeted metabolomics is emerging as a tool in screening for biochemical abnormalities. This research was conducted using the Australian Autism Biobank resource and involved analysis of plasma metabolites to characterise metabolite differences between autistic children and controls.

Gathering Autistic young people's testimony is critical for understanding their lived experience of education and designing settings in which these students can thrive. Despite increasing knowledge in this field, we lack perspectives from a broad range of Autistic students which necessarily limits our ability to build inclusive, supportive environments for all. This study explored the educational experiences of preschool and school-aged Autistic students from diverse age groups, backgrounds, and educational settings.

Alexithymia—a trait characterized by difficulties in emotion processing—is of high interest in the autism field. However, the lack of validated alexithymia measures for autistic individuals limits progress. This study aimed to address this gap by examining the psychometric properties of the Perth Alexithymia Questionnaire (PAQ) across autistic and non-autistic samples. Using the PAQ, we investigated how alexithymia manifests in autistic individuals and its links with poor mental health outcomes (anxiety).

Approximately 8% of all children experience developmental and mental health conditions. Similarities in characteristics across neurodevelopmental conditions-such as difficulties in communication and language, social interaction, motor coordination, attention, activity regulation, behavior, mood, and sleep-make it challenging to attribute these characteristics exclusively to specific diagnoses and assessments. The purpose of this study was to identify symptomatic domains across neurodevelopmental conditions in children and to explore dimension reduction for transdiagnostic assessment. 

Autism genetics has historically attracted a substantial proportion of autism research funding internationally. However, more recently, several controversies centered on ethical conduct and lack of community consultation have emerged. This has triggered Autistic-led protests for the functional and meaningful inclusion of Autistic voices in the research design.

Preterm birth is associated with a 3.3-fold increased likelihood of autism diagnosis, with lower gestational age conferring higher likelihood. In Australia, autism is typically diagnosed at around age four, potentially missing the optimal neuroplasticity window before age two. The Social Attention and Communication Surveillance-Revised (SACS-R) tool identifies early autism signs in children aged 11-30 months, enabling pre-emptive intervention.

Eye-tracking could expedite autism identification/diagnosis through standardisation and objectivity. We tested whether Gazefinder autism assessment, with Classification Algorithm derived from gaze fixation durations, would have good accuracy (area under the curve [AUC] ≥ 0.80) to differentiate 2-4-year-old autistic from non-autistic children.

Caregiver-mediated supports in general have shown mixed evidence for enhancing language outcomes in infants at higher likelihood of autism. While caregivers play a substantial role in caregiver-mediated supports, little is known about whether caregivers' own subclinical autistic features - known as broader autism phenotype - may moderate infant language outcomes. 

Sex-specific developmental differences in brain structure have been documented in older children and adolescents, with females generally showing smaller overall brain volumes and earlier peak ages than males. However, sex differences in gray matter structural development in early childhood are less studied. We characterized sex-specific trajectories of gray matter volume development in children aged 2–8 years.
