Examining gender effects in autistic written language skills: A small sample exploratory study

Area of Science:

• Neurodevelopmental Disorders
• Linguistics
• Developmental Psychology

Background:

• Gender differences in spoken language among autistic individuals are noted.
• These differences may extend to written language, reflecting shared oral and written language dimensions.
• Research on written language characteristics in autistic adolescents, considering gender, is limited.

Purpose of the Study:

• To investigate gender differences in the written language of autistic adolescents.
• To compare written language characteristics of autistic adolescent females with autistic adolescent males and non-autistic adolescent females across genres.
• To determine if autistic adolescent females exhibit distinct written language features.

Main Methods:

• Exploratory analysis of writing samples from 18 autistic adolescents (11 males, 3 females) and 4 non-autistic females.
• Participants completed persuasive, expository, and narrative writing tasks.
• Comparison of sample length, writing productivity, syntactic length, vocabulary diversity, and macrostructure.

Main Results:

• Autistic males wrote significantly shorter expository samples than non-autistic females.
• Autistic males exhibited lower writing productivity in persuasive and expository genres compared to both autistic females and non-autistic females.
• Several other comparisons showed large effect sizes but did not reach statistical significance due to small sample size.

Conclusions:

• Small sample sizes limit generalizable conclusions.
• Observed gender-specific findings differ from previous studies combining autistic groups.
• Combining autistic females and males may obscure distinct written language characteristics.
