Options of Working Memory Trainig
de Gray, Klára ; Páchová, Anna (advisor) ; Preiss, Marek (referee)
The Options of Working Memory Training Abstract: The theme of this diploma thesis is the possibilities of working memory training. From the analysis of nowadays literature we found out that the field of stimulus material (witch is contained in training programs) has not been researched much. The aim of this work is to find out whether there is a connection between the type of stimulus material (within the abstraction and modality level), performance and memory strategies. For this purpose we selected the N-Back Campaign training program. And provide it with visual and verbal tasks in a differen king of abstraction level. These tasks were conducted by fifty respondents. After that, several semi-structured interviews were conducted, which helped us to understand the processes associated with N-back tasks. Using statistical analysis, we came to the conclusion that the type of stimulus material is significantly related to the performance in n-back tasks: with increasing rate of abstraction the performance decreases and that visual N-back task achives with higher scores. Furthermore, it has been found that there are specific strategies that correspond to a certain degree of stimulus abstraction or modalities (vision, hearing). Therefore, we think that stimulus material in N-back tasks can have a significant...

Inhibition control in Obsessive-Compulsive Disorder
Francová, Anna ; Preiss, Marek (advisor) ; Juríčková, Veronika (referee)
The response inhibition ability is part of executive functions, which may be defined as a set of higher cognitive processes particularly located in the frontal-subcortical circuits. Since the main obsessive-compulsive disorder (OCD) symptoms seem to be relevant to the inability of inhibiting certain stimuli, it can be assumed that response inhibition in these patients will be disrupted. Studies related to this topic have brought inconsistent results. Our research dealing with OCD patients has focused on two dimensions of the response inhibition - the behavioral inhibition, which generally includes the behavior control (for instance impulse control), and the cognitive interference, which is considered to be the cognitive component of inhibition process and is mostly associated with the control of internal cognitive processes. The first part of our research included the verification of hypothesis, stating that the increased severity of obsession is associated with the degree of disrupted ability of cognitive interference, while the severity of compulsions correlates with the degree of disrupted performance in tests measuring behavioral inhibition. The second research objective was to clarify whether the inhibition response ability was different between patients when the predominance of symptoms was...

Test-retest reliability in integrity testing
Kozárová, Adéla ; Preiss, Marek (advisor) ; Ševčíková, Marcela (referee)
This thesis deals with personal integrity and its testing for the job tender. The main objective is to determine the test-retest reliability of the integrity test, which is currently being developed and studied at the National Institute of Mental Health in Klecany. Another aim of the work is to compare the Czech version of the integrity test, a whole set of psychological tests designed to investigate the integrity intended for recruiting new employees, and the findings of foreign tests, which are used primarily in the United States. The use of integrity tests is a common practice abroad in the selection process of new employees, for example in lower administration or positions working with money. Work has both theoretical and practical character. The theoretical part summarizes the findings about integrity from authors throughout history, present information about foreign integrity test (types, weaknesses, ethical issues of testing, the proposed rules for the implementation of integrity tests for job tenders for organization, etc.). Finally, it discusses psychometrics and required characteristics for quality tests. The practical part is based on a test-retest study that was conducted on a sample of 51 respondents in the time interval of 4 to 5 months. Respondents were repeatedly presented with a...
