Ecological validity research of Attention test
Bláhová, Lucie ; Preiss, Marek (advisor) ; Rendl, Miroslav (referee)
This bachelor thesis focuses on the issue of attention research, mainly from the neuropsychological point of view. It is an empirical study divided into two parts: The first theoretical part introduces the history of attention research, defines attention and presents the current theories of attention: Broadbent's Filter model, The Feature-Integration theory from Anne Treisman, David LaBerge's theory and Michael Posner's concept of attention. The second part of the work, the empirical part, is based on the discussed concept of attention, mainly from neuropsychologist Michael Posner. The purpose of the research study is to explore the ecological validity of Michael Posner's attention test - Attention network test (ANT). The following questionnaires were chosen as the methods for measuring the real-life attention: CFQ (Cognitive failure questionnaire), EMQ (Everyday memory questionnaire) and DEX (Dysexecutive questionnaire). The results of the study did not confirm the significant statistical correlation between results in Attention Network Test and scores in self-reported questionnaires, but the bachelor thesis' contribution's to ecological validity research can still be seen. KEYWORDS: Attention, Attention research, Ecological validity, ANT, Cognitive failure

The Ecological Validity of the Tests of Executive Functioning in Patients with Schizofrenia
Drozdová, Kristýna ; Kulišťák, Petr (advisor) ; Krámská, Lenka (referee) ; Bahbouh, Radvan (referee)
Aim: The current study investigated a pattern of associations between executive functions and everyday functioning in a sample of schizophrenia patients with the aim to specify the ecological validity. The ecological validity as a specific form of external validity refers to the extent of the relation of the test outcome measures and patients' behaviour in everyday situations. Sample and methods: A sample of 77 patients (22 women and 55 men) with the diagnosis of schizophrenia or schizoaffective disorder, who met study inclusion criteria, was assessed with several executive function tests: Wisconsin Card Sorting Test (WCST), Trail Making Test B (TMT B), Phonemic Verbal Fluency Test and Semantic Verbal Fluency Test (VF), Similarities from Wechsler Adult Inteligence Scale (WAIS III), Rey-Osterrieth Complex Figure Test in Boston Qualitative Scoring System (BQSS), and with rating scales for patients' behavior in everyday situations - Personal and Social Performance Scale (PSPs), newly developed clinical scale (CliSca), Interview for Assessment of Insight (SAI) and patients' self rating in Social Functioning Scale (SFS). Relationships between demografic measures and test outcomes were examined. Results: Verbal fluency tests did correlate significantly with the newly developed clinical scale that seems...

Ecological validity of cognitive training research
Bláhová, Lucie ; Preiss, Marek (advisor) ; Viktorová, Ida (referee)
This Master thesis is focused on ecological validity of a cognitive training in university students. Forty-five students participated in three months research during which 30 of them took regular personalized cognitive training using CogniFit programme on their computers. The study examines the impact of the cogntitive training on everyday cognitive functioning of students. The scientific methods used for the ecological validity research were the following self-reporting questionnaires: Cognititive Failure Questionnaire, Everyday Memory Questionnaire and Dysexecutive Questinnaire. Students also filled in Schwartz Outcome Scale - 10 and Self-image questionnaire for detailed exploration of more variables. For the research, we applied test-retest design and used control group of fifteen students for results comparison. Analysis of the gathered data proved little evidence of ecological validity of cognitive training, which can be attributed to considerable cognitive stress at students. An unexpected outcome of the study which proved to be very significant is relation between executive functions and well-being of a student. This relation was confirmed repeatedly. Possible improvements of methodology and also problem with randomization of students is discussed. Proposal for the further development of...
