Abstract

Brain-Computer Interfaces (BCIs) provide a direct communication channel from the brain to an output device. This paper focuses on the pyschological concept of the ``locus of control of reinforcement'' (LOC) developed by Julian Rotter. Here we report from a study with twelve subjects who had no prior experience with BCI feedback. In the beginning of the experiment the subjects filled out two questionnaires for assessing different aspects of LOC. After a calibration measurement the subjects perfomed a feedback run in which they could BCI-control a cursor horizontally. The analysis pointed out a positive correlation between a LOC score related to dealing with technology and the accuracy of BCI control. These preliminary results suggest that a LOC score can be used as predictor of BCI performance.
