Abstract

Brain-computer interfaces provide a way for brain-controlled devices, eliminating the need for limb control. Auditory BCIs further give rise to possibility for motor-impaired patients, specifically since some auditory BCIs do not require eye-gaze control. German native post-stroke aphasic patients suffering from damage in language-specific neural correlates have been shown to regain a higher level of communicative capabilities and increased scores in clinical aphasia assessments after training with a novel auditory ERP-based BCI paradigm for aphasia rehabilitation. This BCI paradigm utilizes a spatial speaker set-up, effectively introducing a spatial component to stimuli, which was shown to increase classification on target versus nontarget stimuli based on the classic oddball paradigm. Stimuli are comprised of a preceding cueing sentence, with the last word missing. The present study aims to gather apt stimuli sets in Dutch and English domains, and setting up the experiment such that pilot studies can be held shortly after. Stimuli sets were found in both Dutch and English, and recordings of these have been made with native speakers. Furthermore, organizational requirements to commence an EEG study have been fulfilled, and a detailed description of future steps for conducting a pilot study in Dutch has been provided.
