Periodic Reporting for period 1 - ROAR (Investigating the Role of Attention in Reading)

Período documentado: 2019-10-01 hasta 2021-09-30

Resumen del contexto y de los objetivos generales del proyecto

The ability to read is undoubtedly one of the most important cognitive skills in modern society. However, because reading relies on many cognitive functions (e.g. vision, attention, memory, linguistic processing, eye movement control), several aspects of the reading process are still poorly understood. The goal of this project was to advance our understanding of the role of attention in reading. We also questioned whether abnormalities in the allocation of attention may be a root cause of problems in reading, such as dyslexia. Anticipating this possibility, we developed a reading interface intended to improve reading in dyslexia.

In total, the project comprised five objectives:
- To reveal word-to-word influences during reading, such as influences of the syntactic categories of words on the ease of recognizing adjacent words.
- To determine the distribution of attention during reading (our findings suggest that multiple words are processed in parallel, at relatively 'deep' levels (i.e. not just letter information, but also information about grammar).
- To determine how the brain computes word order (e.g. in the phrase "Do love you me?" many readers do not notice the incorrect word order. Our research suggests that this is due to grammatical constraints that are in play while readers process multiple words simultaneously).
- To find out whether dyslexia may be caused by attentional problems.
- To summarize current knowledge about the reading process in a computational model - that is, a computer implementation of our current theoretical framework, called OB1-reader.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

The five objectives were largely achieved, and disseminated through (open-access) publications in peer-reviewed scientific journals.

In short, we established that during reading, your attention extends beyond the word that you're looking at. This means that while you're looking at (and trying to recognize) a word, you're (either consciously or sub-consciously) also processing information from surrounding words. These influence the recognition process. We found that this widespread attention is rather innate: it is depicted even by children who have just learned how to read.

In other studies, we used the notion of widespread attention to develop an interface intended to improving reading in patients with macular degeneration. This interface appears to work really well in participants for whom we simulated a foveal scotoma (blind spot) using eye-tracking technology. That is, we have a successful proof of concept in visually healthy participants for whom we simulated the disease. The efficacy of our interface is still to be tested with actual patients.

Various experiments have guided the ongoing development of our model of reading, OB1-reader. This computational model (i.e. it simulates reading behavior (eye movements, word recognition speed) for a given text input) is to help us understand how reading works in the brain. The more the simulations mimic what we observe in actual humans, the more evidence we have for the model's underlying assumptions.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

Ideally, our findings will aid the ongoing development of reading interfaces for populations who have problems in reading (e.g. people with dyslexia or macular degeneration). Our initial tests are promising, and we will continue to work on publically available products.
