The presented thesis deals with an influence of playing aggressive computer games with the following emotional perception of visual - affective stimuli from NAPS database. The theoretical part is focused on the electroencephalogram, emotions, aggression, event related potentials and media and violence. The practical part is focused on methodology and interpretation of results obtained from experiment. The experiment uses 4 groups of participants. Two of them were groups of computer games players. The first group was playing original version of Counter Strike the second one was playing modified non violent version of Counter Strike. The other two groups were groups of non players of computer games and for them were used the same gaming stimulation. All 4 groups were exposure to visual - affective stimuli before and after play and their event related potentials are examined. The thesis is methodologically based on Analysis of variance and paired T test. For data processing and analysis was used EEGlab which is toolbox of Matlab. The results from statistical analysis have not shown any statistically significant differences in visual affective stimuli between groups. |
