Natural language acquisition and gestalt language processing: A critical analysis of their application to autism and speech language therapy / Tiffany L. HUTCHINS in Autism & Developmental Language Impairments, 9 (January-December 2024)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 9 (January-December 2024) Titre : Natural language acquisition and gestalt language processing: A critical analysis of their application to autism and speech language therapy Type de document : texte imprimé Auteurs : Tiffany L. HUTCHINS, Auteur ; Sophie E. KNOX, Auteur ; E. Cheryl FLETCHER, Auteur Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  language impairment /disorder  speech and language therapy  gestalt language? Index. décimale : PER Périodiques Résumé : Background and Aim Recently, there has been a lot of interest surrounding the term gestalt language processor (GLP) which is associated with Natural Language Acquisition (NLA): a protocol intended to support the language development of autistic people. In NLA, delayed echolalia is presumed raw source material that GLPs use to acquire language in a stage-like progression from delayed echolalia to spontaneous speech. The aim of this article is to evaluate NLA in light of relevant literatures to allow scrutiny of NLA claims. Main contributions First, we review the notion of gestalt language and situate it in the broader literature on language styles to update understanding of its significance. We then review the links from gestalt language processing to autism and identify definitional and conceptual problems and clarify the construct 'episodic memory'. We discuss the 'raw material view of delayed echolalia' and identify theoretical and empirical shortcomings. Finally, we review Blanc?s language stages and their accompanying assessment and language support recommendations and challenge their validity. Conclusions & Implications The term 'gestalt language processor' is definitionally and conceptually troubled, the assertion that autistic people are GLPs is misleading and unhelpful, and evidence is lacking that GLP represents a legitimate clinical entity. The theoretical basis of NLA lacks empirical support. NLA stages are implausible and their accompanying assessment and support recommendations lack justification. We recommend the use of alternate, individualized, theoretically-sound, evidence-based, neurodiversity-affirming supports that are sensitive and responsive to the heterogeneity that defines autism.

Symmetry is a fundamental Gestalt principle characterizing many biological shapes. Sensitivity to symmetry was tested using the Picture Symmetry Test, which requires finding symmetry lines on pictures. Individuals with ASD showed decreased sensitivity to symmetry and a correlation of test performance with performance IQ. Decreased sensitivity for symmetry in ASD is discussed in relation to reduced visual experience of faces in early development.

Risky business: How assumptions about evidence can exclude autistic voices / Schea Fissel BRANNICK in Autism, 29-10 (October 2025)  

Public ISBD [article]  inAutism > 29-10 (October 2025) . - p.2632-2634 Titre : Risky business: How assumptions about evidence can exclude autistic voices Type de document : texte imprimé Auteurs : Schea Fissel BRANNICK, Auteur Article en page(s) : p.2632-2634 Langues : Anglais (eng) Mots-clés : autism  clinical evidence  evidence-based practice  Gestalt Language Development  neurodiversity Index. décimale : PER Périodiques Résumé : Gestalt Language Development has been proposed as a theoretical foundation for neurodiversity-affirming intervention, yet its adoption remains controversial. Critics cite limited high-quality research as justification for rejecting its use, raising valid concerns about its scientific backing. However, such rejection rests on two assumptions that may lead to risky clinical decisions: (1) that research evidence should be the sole or primary driver of evidence-based practice and (2) that research-backed interventions are inherently neurodiversity-affirming. Using Gestalt Language Development as an example, this letter critiques these assumptions and illustrates how over-reliance on research alone-without integrating clinical expertise and autistic perspectives-can delay meaningful, inclusive care. I argue that centering autistic voices is essential to both neurodiversity-affirming practice and evidence-based decision-making. A more balanced model of evidence-based practice is needed-one that evaluates emerging interventions not only by their research base but also by their alignment with autistic values and their impact in clinical practice.Lay Abstract Many autistic individuals and clinicians find Gestalt Language Development to be a helpful approach for supporting autistic communication. However, some researchers argue that Gestalt Language Development should not be widely used until stronger research evidence is available. This argument introduces two risks. First, it assumes that research is the only kind of evidence that matters-overlooking the value of autistic lived experience and clinical expertise in making good intervention decisions. Second, it assumes that research-based interventions are automatically neurodiversity-affirming, even when they are developed without input from autistic people. This letter argues that excluding autistic voices from intervention decisions is risky. A more balanced approach to evidence-one that includes autistic perspectives, clinical expertise, and research-leads to inclusive, more responsive, and more effective support. While research on Gestalt Language Development is still growing, real-world experiences from autistic people and families offer valuable insight into what works and why it matters.

Typical perceptual organization in autism: Perceptual grouping and spatial distortion / Ravit AVRAAM in Autism Research, 12-11 (November 2019)  

Public ISBD [article]  inAutism Research > 12-11 (November 2019) . - p.1623-1635 Titre : Typical perceptual organization in autism: Perceptual grouping and spatial distortion Type de document : texte imprimé Auteurs : Ravit AVRAAM, Auteur ; Nahal BINUR, Auteur ; Bat-Sheva HADAD, Auteur Article en page(s) : p.1623-1635 Langues : Anglais (eng) Mots-clés : autism  gestalt principles  grouping  implicit  local global processing  perceptual organization Index. décimale : PER Périodiques Résumé : The extensive literature on global-local processing in people with autism spectrum disorder (ASD) has recently shifted from arguing for a processing impairment among those with ASD to positing an attenuated preference for global processing. One suggestion is that the fast extraction of the global gist is less efficient in ASD, in contrast to the superior attention-driven processing of local elements. To examine this claim of attenuated global processing, the present study tested how perceptual grouping affected the global organization of visual scenes, specifically testing the claim of less mandatory, more optional global processing in ASD. Participants judged the distance between grouped and ungrouped elements in displays in which illusory distortions were inherent in configurations exemplifying the Gestalt principles of organization. Results from six experiments manipulating different Gestalt cues showed a consistent pattern, indicating that for individuals with ASD, as for typically developed (TD) individuals, grouping processes are organizational in nature, incorporating the grouping of related elements while parsing these from other unrelated elements. This parsing is accompanied by distortions in the spatial relationships perceived in the visual scene. ASD participants exhibited an overall larger tendency to overestimate the distances, but they also demonstrated typical perceptual organization processes that were robust and mandatory and, as in neurotypicals, affected the perception of the whole scene. Autism Res 2019. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: It is known that individuals with autism spectrum disorder (ASD) perceive the world in a different way than their typically developed (TD) peers. While TD individuals exhibit strong bias toward processing the global structure of visual scenes, individuals with ASD exhibit enhanced perception of the local elements. We showed that when the local and global levels are not competing, individuals with autism demonstrate robust global organization that operates even when not directly instructed.

She was not involved in  project design, implementation, or data analysis. She reviewed and edited the  final manuscript. No other authors have any competing interest to report. Index. décimale : PER Périodiques Résumé : BACKGROUND: Minor physical anomalies (MPAs) are congenital morphological abnormalities linked to disruptions of fetal development. MPAs are common in 22q11.2 deletion syndrome (22q11DS) and psychosis spectrum disorders (PS) and likely represent a disruption of early embryologic development that may help identify overlapping mechanisms linked to psychosis in these disorders. METHODS: Here, 2D digital photographs were collected from 22q11DS (n = 150), PS (n = 55), and typically developing (TD; n = 93) individuals. Photographs were analyzed using two computer-vision techniques: (1) DeepGestalt algorithm (Face2Gene (F2G)) technology to identify the presence of genetically mediated facial disorders, and (2) Emotrics-a semi-automated machine learning technique that localizes and measures facial features. RESULTS: F2G reliably identified patients with 22q11DS; faces of PS patients were matched to several genetic conditions including FragileX and 22q11DS. PCA-derived factor loadings of all F2G scores indicated unique and overlapping facial patterns that were related to both 22q11DS and PS. Regional facial measurements of the eyes and nose were smaller in 22q11DS as compared to TD, while PS showed intermediate measurements. CONCLUSIONS: The extent to which craniofacial dysmorphology 22q11DS and PS overlapping and evident before the impairment or distress of sub-psychotic symptoms may allow us to identify at-risk youths more reliably and at an earlier stage of development.
