Plechatá, Adéla ; Kebza, Vladimír (advisor) ; Loneková, Katarína (referee)
Cognitive deficit presents a significant problem affecting the life of schizophrenia patients. Despite the variability of the deficit, which influences almost all cognitive domains, the most profound seems to be deficit in memory and executive functioning with direct impact on daily functioning of patients with schizophrenia. As the pharmacologic interventions do not seem to bring satisfying results, the cognitive remediation seems to bet the most effective way of intervention of the deficit. Efficacy of cognitive remediation approach was repeatedly confirmed on the level of structural and functional changes of the brain. Nevertheless, often discussed are the issues of ecological validity of cognitive remediation and its controversial ability of transfer of acquired abilities and skills into the real life. In this work, we present development of a new method potentially applicable in the remediation of deficit of declarative memory in schizophrenia patients designed in ecologically valid environment of virtual supermarket. In the first two pilot studies, we tested the functionality of the task in the healthy volunteers and we compared their performance in the virtual task with the results in standard psychological memory tests. After considering the findings from the pilot studies, we verified the...
