CoRe Lab

Student using the CoRegistration (CoRe) Lab

In the CoRegistration (CoRe) Lab we simultaneously record participants’ eye movements and brain potentials to investigate cognitive processes as they occur millisecond-by-millisecond in natural contexts.

Co-Registration is a new and non-invasive technique that allows to precisely time-lock brain potentials to oculomotor events (fixations and saccades) and examine the electrical brain activity associated with cognitive processes that occur within an eye fixation.

Using this methodological approach, we aim to untangle the time course of the foveal and parafoveal processes that underlie human cognition.

FACILITIES

Electroencephalography (EEG)

64-Channels BrainCaps with passive electrodes (Brain Products UK Ltd), SynAmps RT 64-channel amplifier (Compumedics Neuroscan), Faraday Cage.

Eye tracker (ET)

Desktop Mount Eyelink 1000 Plus (SR Research) with setup that enables data to be recorded simultaneously with EEG.

Data Analysis Computers

Members of the lab have access to high-hand computers for data analyses of the co-registered data. In addition to the standard computing software, these computers are equipped with specialist software, including Matlab and its toolboxes (EEGLAB, EYE-EEG, Fieldtrip), R, Experiment Builder, Data Viewer.

Research Themes

Foveal and Parafoveal Processing in Reading

Current experiments seek to further our understanding of the time course of the cognitive processes that underlie natural reading. We know that when we read, we process the word that we are currently fixating (in fovea) and, to a certain degree, the word to the right of fixation (in parafovea). Using co-registration it is possible to time lock the brain potentials to the fixation onset on particular words embedded in a sentence (thus, recording fixation-related potentials; FRPs). By manipulating the characteristics of the words presented in foveal and parafoveal vision, we can investigate what type of information is extracted and when.

Face Processing in Typical and Atypical Populations

Current projects investigate face processing using co-registration to provide insights into the temporal dynamics of the cognitive mechanisms involved in face perception and recognition. We are particularly interested in understanding whether there are differences in the cognitive mechanisms that underlie face processing in individuals with typical versus atypical (e.g., Autism Spectrum Disorder) development, and whether they are limited to foveal processing or extend to parafoveal processing.
