Abstract
In this pilot study on movement intention it is assessed whether it is possible
to detect an intention to move based on EEG data. To this end participants
perform a free movement task during which their intention to move is predicted.
When a prediction is made the participant is interrupted. The hypothesis is
that such an interruption leads to an error potential-like response, of which the
amplitude di ers as a function of whether the participant reports an intention to
move. Such a brain response is indeed visible as a result of this experiment and
is consistent across participants. The amplitude of the brain response is greater
when participants report not having had an intention to move at the time of the
prediction. Based on the limited amount of data collected this di erence is not
statistically signi cant, however a larger study should be conducted to draw nal
conclusions.
