Abstract
Neurofeedback literature reveals a gap of knowledge when it comes to the question what
threshold to use and whether it is better to use a sensitive or a specific one. For this purpose,
the aim of this study was to find out the effect of different amounts of rewards in
neurofeedback and the increase in individual upper alpha amplitude. 42 participants
volunteered. Most of them were students and the rest was recruited through the social network
of the experimenters. The data of 26 participants were used, because of problems with
measuring and high noise or muscle tension. Participants have been randomized in two
conditions, receiving a reward in either ten or seventy percent of the time they had an
amplitude higher than the threshold. Based on the previous measurement. The procedure
consisted of eight different blocks, where in five of them neurofeedback training was given.
The results show a significant interaction between the reward condition and the
neurofeedback training, which was measurable through the individual upper alpha amplitude,
which rose more in the seventy percent condition compared to the ten percent condition. It
can be concluded, that the amount of reward in neurofeedback training does matter and that a
sensitive threshold level benefits an increase in upper alpha amplitude during the training
session more than a specific threshold.
