Dyslexia Eye Tracking COrpus (DECO): First- and Second Language Book Reading in Adults with Dyslexia

Openly available eye-tracking corpora have been indispensable for the progress of psycholinguistic theories of reading. Past corpus work extensively covered typical reading in a range of languages, but left reading difficulties relatively under documented. In this article, we present a novel corpus, the Dyslexia Eye Tracking COrpus (DECO). It includes eye-tracking data collected from 20 Dutch - English bilingual adults with a diagnosis of developmental dyslexia. They read an entire novel (almost 60.000 words), with one half presented in their first language (Dutch) and the other half in their second language (English). After each chapter the participants answered multiple reading comprehension questions. Additionally, all participants completed several measures of linguistic abilities, including vocabulary, spelling, a one-minute reading test and a language questionnaire. This corpus is the largest of its kind and is a direct extension of the existing GECO corpus of typical reading (Cop, Dirix, Drieghe & Duyck, 2017). In combination with GECO, it provides researchers with a unique resource to study naturalistic reading in dyslexia and its intersection with bilingualism. All data and materials will be made available upon publication.
