This study examined: (1) how IQ-DLS discrepancies develop from early childhood through early adulthood, (2) whether childhood factors (e.g., autism features, non-verbal IQ) predict these developmental pathways, and (3) how IQ-DLS discrepancy trajectories relate to adult experiences (e.g., employment, well-being, relationships). Analyses included 92 individuals from the Longitudinal Study of Autism with average or better IQ and repeated assessments of IQ and DLS from ages 2–25 years. Developmental patterns in IQ-DLS discrepancy scores were identified using group-based trajectory modeling. Two trajectory groups were identified: IQ = DLS (commensurate cognitive and daily living skills) and IQ > DLS (weaker DLS than expected for IQ). Most participants had commensurate IQ and DLS across development. When discrepancies emerged, they did so gradually, becoming apparent by mid-childhood. White participants were more likely to be in the IQ > DLS group; participant race was the only early childhood predictor of group membership. IQ-DLS discrepancy trajectories were not significantly associated with adult experiences. In contrast to existing literature, this study suggests autistic individuals with average or higher IQ may not always have persistent deficits in DLS relative to cognitive ability. When discrepancies occurred in this sample, they developed over time rather than being present from early childhood. These findings challenge deterministic assumptions about adaptive function in autism and highlight the importance of sustained opportunities to learn and practice DLS across development.</p>","PeriodicalId":131,"journal":{"name":"Autism Research","volume":"19 7","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aur.70280","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148145595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recorded their behavioral responses and Electroencephalography (EEG) signals to audiovisual congruent syllables, and incongruent syllables that could evoke audiovisual speech integration (i.e., McGurk effect). For the EEG analysis, we further classified autistic children into the autistic McGurk group and the autistic non-McGurk group based on their strength of audiovisual speech integration. Behaviorally, we found reduced audiovisual speech integration in autistic children. At the neural level, we found that: (1) NT children showed an early stage audiovisual processing (indexed by the N1 amplitude), which was altered in two autistic groups; (2) all three groups exhibited a successful audiovisual incongruence detection (i.e., phonological Mismatch Negativity, pMMN); (3) NT and autistic McGurk groups could successfully resolve the audiovisual incongruence (indexed by the restoration of pMMN), but the autistic non-McGurk group could not (indexed by the sustained negative amplitude). Furthermore, we found a distinct temporal decoding pattern between non-McGurk and congruent trials across groups: both NT and autistic McGurk groups exhibited early EEG decoding, whereas the autistic non-McGurk group demonstrated successful decoding during late processing stages.

Despite this knowledge, the exact neurophysiological mechanisms driving these differences and their direct impact on clinical symptoms remain unclear. This study delves deeper into understanding the neurophysiological mechanisms involved in social cue integration, moving beyond mere behavioral observations. Specifically, we investigated how autistic children and typically developing (TD) peers process congruent and incongruent social signals in everyday situations. We compared 34 male autistic (2.5–6 years) versus 34 TD children via eye-tracking and functional near-infrared spectroscopy to measure gaze, pupil dilation, and frontal activation during gesture-face integration. TD children exhibited heightened attention to happy faces while maintaining equal attention to neutral faces and gestures when reward gestures were paired. The ASD group did not demonstrate an effective processing strategy. ASD children exhibited heightened pupil dilation and anterior prefrontal cortex (aPFC) activation in all conditions. Crucially, their gaze patterns and aPFC activation significantly correlated with poorer adaptive functioning and positively predicted autism severity. Autistic children go through a distinct, neurologically demanding, and inefficient process to integrate multimodal social cues. This inefficient compensatory attempt results in a metabolically costly physiological state, which is directly connected to the core challenges of ASD.

Drawing heavily on insights translated from pediatric and transdiagnostic literatures, we propose that irritability in autistic individuals often reflects a psychophysiological stress or threat response, rooted in a vulnerable neurobiology (e.g., sensory sensitivities, intolerance of uncertainty), but may also stem from intrinsic neurobiological dysregulation independent of environmental triggers. The current treatment paradigm for autistic adults, largely extrapolated from pediatric antipsychotic trials, leaves these adults critically underserved due to a lack of evidence-based treatments, clinical trials, or validated tools to measure their internal experience. This viewpoint deconstructs irritability, differentiating its affective nature from aggression, and highlights heterogeneity across the lifespan and support needs. We critique the limitations of current assessment methods and recommend a shift toward a multi-modal strategy integrating self-report (when feasible) with objective, physiologically-informed tools (e.g., wearable biosensors) and nuanced observer reports. We argue that the field is poised for neuroscience-informed treatment innovation—including novel pharmacological agents and adapted psychosocial interventions—but is hampered by a lack of rigorous clinical trials in adults.
