The Effect of Neurofeedback Training on Variables of Attention in Healthy Adults

The aim of present study is to examine the effect of neurofeedback training on attentional processes in two groups of healthy adult participants. During the experiment, participants in the experimental group were required to complete two puzzles displayed on the computer screen while having neu-rofeedback training. During this procedure, performance on the puzzles was based on participants’ brain activity that was recorded from the Cz area. Moreover, before and after completion of seven neurofeedback sessions, Stroop task was used to measure selective attention performance. Results for the Stroop task showed that although there was a significant reaction time difference before and after the neurofeedback training, there was no significant main effect of group (experimental vs. control group). Furthermore, the reaction time to complete the puzzles across the sessions did not differ significantly between the experimental and the control group. Improving the training program by increasing the number of training sessions and employing a more attention-demanding task in the training sessions might have resulted in an expected effect of neurofeedback
