Specificity of phonological representations in school-age high-functioning ASD children

Area of Science:

• Linguistics
• Developmental Psychology
• Speech-Language Pathology

Background:

• Phonological representations are crucial for language development.
• Understanding speech sound disorders in children with high-functioning autism spectrum disorder (HF-ASD) is essential.

Purpose of the Study:

• Investigate speech errors and phonological representations in Greek-speaking children with HF-ASD.
• Examine the relationship between stored phonological representations and speech output.
• Utilize Stackhouse and Wells' (1997) model for analysis.

Main Methods:

• Administered phonological, naming, and non-word repetition tasks.
• Conducted a receptive phonological task on a subgroup.
• Categorized HF-ASD children into ASD with Speech Sound Disorder (SSD) or ASD without SSD based on performance.

Main Results:

• HF-ASD children showed more speech errors and difficulties with non-word repetition and phonological representations compared to typically developing (TD) peers.
• Naming abilities were comparable between HF-ASD and TD children.
• Both ASD subgroups performed similarly on receptive tasks, indicating unspecified phonological representations.

Conclusions:

• Results support distinct phonological representations for speech input and output.
• Receptive tasks are vital for evaluating underlying phonological knowledge.
• This approach aids clinicians in identifying speech breakdown levels.
