AI Article Synopsis
- Research shows that autistic individuals face unique challenges in integrating audiovisual speech, but results vary due to different research methods.
- In a systematic review of 18 studies involving nearly 1,000 participants, autistic individuals exhibited significantly poorer audiovisual integration than non-autistic peers.
- The study recommends future research to focus on larger sample sizes, include more adult participants, and standardize methodologies to reduce inconsistencies in findings.
Article Abstract
Research has indicated unique challenges in audiovisual integration of speech among autistic individuals, although methodological differences have led to divergent findings. We conducted a systematic literature search to identify studies that measured audiovisual speech integration among both autistic and non-autistic individuals. Across the 18 identified studies (combined N = 952), autistic individuals showed impaired audiovisual integration compared to their non-autistic peers (g = 0.69, 95 % CI [0.53, 0.85], p <.001). This difference was not found to be influenced by participants' mean ages, studies' sample sizes, risk-of-bias scores, or paradigms employed. However, a subgroup analysis suggested that child studies may show larger between-group differences than adult ones. The prevailing pattern of impaired audiovisual speech integration in autism may have cascading effects on communicative and social behavior. However, small samples and inconsistency in designs/analyses translated into considerable heterogeneity in findings and opacity regarding the influence of underlying unisensory and attentional factors. We recommend three key directions for future research: larger samples, more research with adults, and standardization of methodology and analytical approaches.

Departamento de Personalidad, Evaluación y Tratamiento Psicológicos, Universidad de Salamanca, Salamanca, Spain.
Introduction: It is crucial to provide a quality educational response to the needs of autistic children across various mathematical domains. However, there is no consensus on which of the early skills have the greatest predictive effect in the short and long term within these domains. Therefore, this research aimed to a) compare early numerical skills and mathematics domains, and 2) analyze the predictive value of early numerical skills into mathematics domains.

Purpose: Autistic adults experience high rates of traumatic events and PTSD. However, little work has evaluated motor vehicle accident (MVA) related trauma symptoms. The goal of this brief report was to provide pilot data characterizing MVA-related peritraumatic reactions, trauma symptoms, and rates of PTSD diagnosis and mental health service use among Autistic compared to non-autistic adults.

Department of Psychology, University of Cambridge, Cambridge, UK.
Purpose: This study explored the narrative coherence of the accounts of an experienced event produced by autistic and neurotypical children (ages 6-15 years) after delays of two weeks and two months.
Methods: The sample comprised 27 autistic children and 32 neurotypical peers, who were interviewed about the event using the Revised National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. The study focused on assessing the narrative coherence of children's reports, emphasizing key story grammar elements and temporal features in their narratives.
Impact of chronic intranasal oxytocin administration on face expression processing in autistic children: a randomized controlled trial using fMRI.
Mol Autism

Department of Neurosciences, Center for Developmental Psychiatry, KU Leuven, Leuven, Belgium.
Background: Difficulties with (non-verbal) social communication, including facial expression processing, constitute a hallmark of autism. Intranasal administration of oxytocin has been considered a potential therapeutic option for improving social difficulties in autism, either by enhancing the salience of social cues or by reducing the social stress and anxiety experienced in social encounters.
Methods: We recorded fMRI brain activity while presenting neutral, fearful and scrambled faces, to compare the neural face processing signature of autistic children (n = 58) with that of matched non-autistic controls (n = 38).
