Studying language comprehension in
autistic minimal, unreliable and non-speakers

Around 30% of autistic people have no or minimal spoken language. Despite a dramatic rise in global funding for autism research over the past few decades, autistic non-speakers have remained chronically under-researched. As a result, we know very little about autistic non-speakers' language comprehension abilities.

​

The aim of our research program is to address this research gap by developing novel methods for studying language comprehension in autistic minimal, unreliable and non-speakers.​

​

​To this end, we are currently running two studies, led by Dr Hannah Rapaport.

Study 1: Brain signatures of language comprehension

The aim of this study is to reliably detect 'brain signatures' of language comprehension in autistic non- and minimal speakers. 

​

We use a brain recording tool called 'electroencephalography' (EEG) to record participants' brain activity as they listen to a series of spoken sentences.

 

Some of the sentences end in a word that is congruent with the rest of the sentence (e.g., The clouds are high up in the sky), and some end in a word that does not make sense in the sentence (e.g., The clouds are high up in the door).​

​​A difference in the brain response between the congruent and incongruent sentences would offer neural evidence of language comprehension.

​

We are analysing the data and look forward to sharing the results soon.​

Study 2: Adapting classic vocabulary tests to accommodate autistic non-speakers

Classic vocabulary tests may underestimate autistic non-speakers' language abilities because they are not designed to accommodate autistic non-speaker's needs.

 

The aim of this study is to develop new tools to characterise language comprehension in autistic non-speakers who communicate using letterboards.

​

We adapted a classic picture vocabulary test to better accommodate the needs of autistic non-speakers.

 

Participants are asked to:

A) Select one of four pictures that matches a spoken word, or

B) Select one of four words that matches a spoken definition.

​

Participants respond using a number board and work alongside a familiar  letterboard practitioner who cannot themselves see the pictures.

We would love to hear from autistic non- and minimal-speakers, their families, practitioners and other stakeholders.
