Conventions for unconventional language: Revisiting a framework for spoken language features in autism

Area of Science:

• Linguistics
• Developmental Psychology
• Neurodevelopmental Disorders

Background:

• Autism is often associated with distinctive spoken language features, such as repetition, neologisms, and pedantic speech.
• These features have historically lacked consistent terminology, definitions, and clinical interpretation.
• Disagreement persists regarding the theoretical and applied understanding of these language characteristics.

Purpose of the Study:

• To update and expand a framework for unconventional language in autism spectrum disorder (ASD).
• To incorporate a wider spectrum of non-generative (echolalia, self-repetition) and generative (idiosyncratic phrases, neologisms, pedantic language) features.
• To propose transitional language features bridging non-generative and generative domains.

Main Methods:

• Review of existing literature on unconventional language in autism.
• Expansion of a previously established framework to include a broader range of linguistic features.
• Analysis of definitions, measurement approaches, and correlates of these features.

Main Results:

• An updated framework encompassing non-generative, generative, and transitional language features in autism.
• Review of definitions, measurement strategies, and individual/contextual factors related to these features.
• Identification of potential transitional features like mitigated echolalia and gestalt language.

Conclusions:

• The proposed framework offers a unified taxonomy and nomenclature for unconventional language in autism.
• This unified system aims to facilitate further research and interpretation of autism-related language.
• The framework has implications for understanding autism and language development, guiding clinical assessment and intervention.
