Profile

Biography

I am a cognitive neuroscientist interested in how atypical language development, due to early onset deafness, impacts language and reading skills, at both the behavioural and neuropsychological levels. After obtaining my PhD in Cognitive Neuroscience at the University of La Laguna (Spain), I was a postdoctoral researcher at the Center for Mind and Brain at the University of California Davis (USA) for three years. Then I spent 4 years as a research fellow at the UCL Deafness, Cognition and Language research centre (UK) and a further 3 years as an independent research fellow at the University of Valencia (Spain). After a short lectureship at University of East London I joined the department in July 2019. Some of the highlights of my research are: In studies of sign language processing, I found that deaf signers process both phonological and semantic information of signs using similar—but not identical—mechanisms as hearing people do to understand words. I demonstrated that some idiosyncrasies of signed languages, for example, the stronger link between phonology and semantics in signs, are reflected in the brain electrophysiological signature of sign comprehension. I also found a stronger left lateralization for sign than spoken production, possibly reflecting the specific phonological demands of signed languages. In studies of written language processing, I have demonstrated that deaf readers can use phonological information of words automatically. However, unlike hearing readers, the use of this phonological information did not contribute to reading comprehension attainment. I have also shown that skilled deaf readers have a stronger connection between the orthographic and lexical-semantic level of processing than less skilled deaf readers. In future studies, I plan to investigate how the interplay between form and meaning of written words affects comprehension of longer texts in deaf readers. My long-term research goal is to identify the variables that contribute to reading proficiency in people born deaf, including those with a cochlear implant.

My research has focused on how atypical language development, due to early onset deafness, impacts language and reading skills, at both the behavioural and neuropsychological levels. I am particularly interested in how the use of phonological and semantic properties of language influence reading attainment in deaf people. My long-term research goal is to identify the variables that contribute to reading proficiency in people born deaf, including those with a cochlear implant. This knowledge would allow us to develop efficient tools to identify deaf children who are more likely to struggle with literacy. Furthermore, identifying alternative mechanisms for efficient reading, in the absence of a well specified phonological representation, would inform training programmes for deaf people and also for hearing people that struggle with reading (e.g. visual learners, some dyslexic children or late bilinguals—who might lack the ability to distinguish phonological contrasts not present in their native language). My work will also inform our understanding of the reading process more broadly. This could allow for more parsimonious theories of language processing and literacy development, that should include language processing mechanisms not necessarily dependant on sound-based representations.

Integration of phonology and meaning during sentence reading in deaf people

Deaf people often find reading an extremely difficult task. Most deaf adults only achieve a reading level equivalent to that of a 10-year-old, and this may negatively impact their academic achievement as well as their social and emotional well-being. Besides general language skills, understanding the meaning of printed words requires fast and accurate decoding of their orthography and phonology. As people born deaf have limited access to the phonology of speech, their poor reading skills are often explained in terms of their reduced use of spoken phonology during accessing the meaning of the written words (Perfetti & Sandak, 2000 but see Mayberry et al., 2011 for a metanalysis offering a different view). However, deaf people perceive the world mainly through their eyes and they tend to show excellent visual processing skills (Belanger et al., 2012). Recent research suggests that the connections between the visual-orthographic and the semantic levels of language processing might have a stronger influence than phonological processing on deaf people’s reading ability. Here's an example of this kind of research, which at the moment is at an early phase of developing appropriate materials and testing a control group hearing participants. Example: Integration of phonology and meaning. Recent Event Related Potential (ERP) research indicates that, when words are presented in isolation, deaf readers access phonological information from words automatically during word recognition. Interestingly, their use of phonology at the single word level is not related to their reading ability in the same way that it is related in hearing readers (Gutierrez-Sigut et at. 2017; 2018). However, there is a possibility that deficits in phonological processing only have a clear impact when the difficulty of the task is increased, for example by having to integrate the meanings of several words in a sentence. This project would investigate whether using phonological information from words modulates access to meaning during sentence reading. For example, we will look at the time course of the brain’s electrophysiological response to sentences like these: 1) She worked at a really isolated cabin, she wanted to find some peace to write 2) She worked at a really isolated cabin, she wanted to find some piece to write 3) She worked at a really isolated cabin, she wanted to find some socks to write Then we will look at the relationship between the ERP waves and a measure of reading ability. The goal of this line of research is to identify when—if at all—deficits in the use of phonological information explain poor reading ability in deaf people.
