This study used EEG during cartoon viewing to assess semantic processing in children with Autism Spectrum Disorder (ASD). Findings reveal unique patterns in how children with ASD process emotional semantic information.
Area of Science:
- Neuroscience
- Developmental Psychology
- Computational Linguistics
Background:
- Autism Spectrum Disorder (ASD) is marked by social communication deficits, including difficulties in semantic processing.
- Traditional neuroimaging methods for studying language in ASD lack ecological validity, especially in young children.
- Assessing semantic processing in children with ASD requires naturalistic and engaging methods.
Purpose of the Study:
- To introduce a novel electroencephalography (EEG) based approach for evaluating atypical semantic processing in children with ASD (4-10 years).
- To investigate semantic processing preferences and neural mechanisms in children with ASD using a machine learning framework during cartoon viewing.
- To explore distinct patterns in semantic information integration and emotional semantic dimension processing in children with ASD.
Main Methods:
- Collected EEG data from children with ASD (4-10 years) while they watched cartoons.
- Developed a machine learning model combining pretrained language models and regression techniques.
- Utilized the Six-dimensional Semantic Database and EEG topographical mapping to analyze semantic processing across word dimensions.
Main Results:
- The developed semantic processing model achieved high sensitivity (91.3%) and moderate specificity (61.0%), with findings replicated in validation analyses.
- Identified distinct patterns in how children with ASD process semantic information compared to neurotypical individuals.
- Observed specific differences in the integration and neural response to emotional semantic dimensions in children with ASD.
Conclusions:
- This novel EEG approach during cartoon viewing offers a more ecologically valid method for assessing semantic processing in children with ASD.
- The findings highlight unique semantic processing patterns in ASD, particularly concerning emotional content.
- This research provides a foundation for potential auxiliary diagnostic tools for ASD in naturalistic settings, addressing clinical needs.
