A brain-computer interface (BCI) is a method of communication that utilizes the scalp recorded electroencephalogram (EEG). A BCI requires no movement, making it a viable communication option for people who are severely disabled. Most BCI research has focused on improving BCI technology through advances in signal processing and paradigmatic manipulations. Research has recently begun to examine the influence of psychosocial factors on BCI performance. Examining psychosocial factors may be particularly important for disabled people who have several co-morbidities. The purpose of the current study is to examine the hypothesis that participants will be more motivated in a free spelling paradigm than in a copy spelling paradigm. Participants completed copy- and freespelling tasks, order was counterbalanced. Motivation was measured after each task. Preliminary data suggests an increase in motivation after the second task regardless of which task was performed second. No differences were observed in performance accuracy between the two tasks.
