Is the locus of control of reinforcement a predictor of brain-computer interface performance?

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.
