The effectiveness of neurofeedback was evaluated in a 30-session theta/beta frequency band training with six children of the same age with comparable verbal and nonverbal intelligence. Five of the children had not disclosed attention deficits or any neuropsychological and other neurological abnormalities and formed the control group, whereas the subject, AS, had an attention-deficit/hyperactivity disorder (ADHD). Before, and seven months after training, the attention levels of both groups were measured by the d2-R Attention Stress Test. The leading hypothesis to be answered in this paper is whether theta/beta frequency band training improves performance in this test of attention. The evaluation of this test showed that AS improved significantly across all scales of attention performance (concentration power, processing speed, and number of errors). The influence of neurofeedback training on EEG frequency bands over time was also investigated. It turned out that changes in attention already occurred in the first treatment sessions, which were not reflected in the values of the theta/beta quotient due to the increase in the absolute power of the theta band.
