ABSTRACT

PURPOSE: Milton’s theory of double empathy posits that the difference in communication styles between people of different neurotypes contributes to mutual misunderstandings. The current quasi-experimental study seeks to expand on research indicating that matched neurotype pairs tend to communicate more effectively than mixed neurotype pairs by examining communication across and within neurotypes in an expository language context.

METHOD: Thirty autistic adults and 28 nonautistic adults were paired in either a matched neurotype or mixed neurotype condition. The pairs’ interactions involved giving and listening to directions to draw an image. Interactions were recorded, transcribed, and coded for communication accuracy, rate, and clarity. Participants also completed a survey about the rapport they experienced in the interaction.

RESULTS: Matched neurotype pairs were significantly more accurate in their communication than mixed neurotype pairs. Rate was fastest among mixed neurotype pairs, but clarity did not differ significantly across conditions. Matched autistic pairs reported significantly lower rapport than other pairs.

CONCLUSIONS: This finding lends further support to the neurodiversity model by demonstrating that autistic communication is not inherently deficient. Further research is necessary to investigate a variety of influences on rate, clarity, and rapport development. Clinical implications include considerations for neurodiversity-affirming communication supports for expository contexts such as classroom directions or workplace instructions.
