Abstract: | This work is concerned with pre-processing and analysis of data measured during the mental rotation task. This task quanties spatial abilities of individuals. Behavioral data, reaction time and EEG signal by standard 10-20 system were measured in a sample of 16 mentally gifted children (10 boys, 6 girls, IQ > 130) aged 15-17. The main aim of the work is to determine the dierences between genders in terms of reaction time, accuracy of the answers and activation of the specic brain regions.
Correlation methods, parametric and non-parametric tests, data-mining methods (feature extraction, feature selection, k-NN, Naive Bayes, Multilayer Perceptron) and visualization of data were used to determine relationship between dierent parameters.
The hypothesis that the reaction time will be shorter for girls and accuracy will be higher for boys was not conrmed, although behavioral data were in the line with expectations (empathy quotient, systemizing quotient) and EEG partially conrmed the existing view concerning brain activity in women and men in the course of the mental rotation.
