Language comprehension and production are remarkably complex activities involving multiple cognitive functions working together at high levels of efficiency. For example, in order to read a single word we need to process the identity and the order of multiple highly similar visual stimuli in close spatial proximity (the letters). Yet, a skilled reader would take just a few hundred of milliseconds to recognize the word and understand its meaning. How can our perceptual and cognitive functions process such complex information in such a short time?
Similarly, in order to utter or write a single word, we need to go all the way from our communicative intentions onto the actual motor behavior that translates them into spoken or written words, retrieving all the relevant semantic, lexical and syntactic representations. Again, this typically happens in a fraction of a second.
In my research, I try to explore the complexities of reading and language production, their cognitive specificities, and in their links with other functions such as visuo-spatial attention, perception, and motor programming.
Letter recognition and reading
In this this research line, I try to understand how the perceptual and cognitive functions are able to process complex visual stimuli such as arrays of letters with the efficiency typically displayed by skilled readers. This is usually done within simple behavioral experiments by exploring the performance of young adult readers in recognizing arrays of letters displayed for very short durations.
By manipulating the position of letters within the strings, their visual quality, the deployment of visuo-spatial attention, the location of the strings in the visual field, and the time of exposure, we can gain insight on the underlying perceptual, cognitive, and attentional mechanisms.
This research line further attempts to understand how simple visuo-perceptual factors may influence reading of actual texts in everyday situations, such as webpages, using measures of eye movements in reading.
Visual word recognition and word production
In order to read and produce words, we need to access, retrieve, and combine multiple sources of information. Orthographic, semantic, lexical, and phonological information interact and combine even within the most simple linguistic task. In this research line, I try to understand the interactions between different levels of processing using behavioral experiments as well as electroencephalographic (EEG) measures during recognition and production of single words.
Links between language processing and motor programming
Language production necessarily requires cognitive processing, to retrieve lexical, semantic, and syntactic information. However, we also need motor programming, in order to enact the behavior that translates our communicative intentions into spoken or written words. In this research line I try to explore the transition between cognitive processing and motor response programming in language.
By doing this, my hope is to tackle the boundary between cognition and action, and the potential interplay between these stages. Typically, this line of research revolves around EEG indexes of motor programming and motor response execution, in order to understand how these are influenced by cognitive processes and variables.
