Change Blindness and Choice Blindness
Denemarková, Martina ; Vranka, Marek (advisor) ; Uhlář, Pavel (referee)
Change blindness and choice blindness are phenomena, research on which is not only interesting, but also essential for better understanding of attention, formation of internal representations, decision making processes, formation and stability of preferences. The thesis introduces change blindness and choice blindness in theoretical relations, briefly submits crosscut of research studies of these phenomena and factors affecting them. In relationship to the literature review part, this thesis also contains a proposal of empirical study investigating the influence of demand characteristics on choice blindness in context of consumer preferences. Keywords: Change blindness Choice blindness Preferences Internal representations Decision making

Scene memorability and change salience: memory-perception relationship
Ptáčková, Barbora ; Lukavský, Jiří (advisor) ; Škaloudová, Alena (referee)
In the thesis, I focus on the relationship between visual memory and the ability to detect changes in photographs. In the theoretical part I introduce the change detection and "change blindness" phenomenon. Next, this work explores visual memory and refers to studies that focused on visual long-term memory and its role in change detection. The objective of the empirical part of this thesis is to map the relation between visual memory (scene memorability) and change detection illustrated on the ability to recognize changes in photographs of indoor and outdoor scenes. Research was conducted by means of an experiment devised in PsychoPy using flicker paradigm. The research sample comprised 42 respondents, mainly university students. Research results did not confirm the existence of a relation between visual memory and change detection. No correspondence was found between these variables, not even at the level of each category, suggesting that change detection depends on other factors than visual long-term memory. KEYWORDS: Change blindness, visual long-term memory, change detection, memorability, perception, experiment
