The paper presents an experiment performed in order to confirm the hypothesis that the level of human cognitive workload can be studied by spectral analysis. The experiment contained intervals ensuring high cognitive load. They were displayed alternately with relaxing breaks. The spectral analysis covered changes in EEG bands including the alpha/theta ratio.
