Use of Sign Language Videos in EEG and MEG Studies : Experiences from a Multidisciplinary Project Combining Linguistics and Cognitive Neuroscience

In this paper, we describe our experiences of bringing together methodologies of two disciplines – sign language (SL) linguistics and cognitive neuroscience – in the multidisciplinary ShowTell research project (Academy of Finland 2021–2025). More specifically, we discuss the challenges we encountered when creating and using video materials for the study of SL processing in the brain. Rather than using still images, the study of SL comprehension is better performed by using videos, thus providing more naturalistic stimuli as observed in face-to-face interaction. On the other hand, in neuroimaging (electroencephalography [EEG]/magnetoencephalography [MEG]), it is vital to track the timing of …
