The research was carried out using quantitative methodology. The test battery consisted of the NEUROP-3 diagnostic tool. The research group consisted of six volunteers. Their mean age was 39.16 years (SD = ± 8.16). From the research results, We proved that during the stay in the ICE environment, there was an increase in impulsivity and a deterioration of attention under stress in the volunteers regarding cognitive domains. However, the results must be evaluated more freely due to methodological limits.
