Comparison of subjective and physiologic perception of experience intensity during repeated stimulation
Polanská, Helena ; Poláčková Šolcová, Iva (advisor) ; Martinec Nováková, Lenka (referee)
This diploma thesis deals with experiencing emotions and emotional habituation. The aim of the work was to compare changes in subjectively felt intensity of emotional experience and physiological responses during repeated affective stimulation. In the theoretical part were presented the concepts of affective experience and emotional habituation, their biological basis and methods of investigation. The empirical part is devoted to an experiment in which sets of positive and negative picture (IAPS database) and sets of videos in different order were repeatedly presented to group of 124 people. During the presentation were observed changes in subjective evaluation of stimuli and in physiological responses (skin conductance, skin temperature). The habituation process has been tested with regard to the order of stimuli. The results demonstrated that habituation process were present at a subjective level. Also habituation process occured for the physiological indicator, the skin temperature in the part of group that saw for the first stimulus set of positive videos. The habituation of skin conductance did not appear, on the contrary its values increase with a series of repetitions. There is some probability, that subjective and physiological habituation are independent to each other. Previous affective...

Affective state elicitation using pictoral and audiovisual stimuli: A comparative study
Novák, Ondřej ; Kebza, Vladimír (advisor) ; Lukavský, Jiří (referee)
Both pictures and films are widely used elicitors in experimental approach to emotions. However, there is no consensus regarding their relative impact. I describe conceptual underpinning of these methods, their theoretical comparison, and related methods. In a study of 124 students I assess and compare the impact of pictures and films on experiential, behavioural and physiological reactions. There were stronger reactions in response to positive film than to positive pictures. Negative film and pictures were similar in strength yet different in kind of reactions they yielded. The difference can be explained by different temporal characteristics of both methods. Present study is the second study dealing with this topic, and the only study that engaged multiple reaction levels. Powered by TCPDF (www.tcpdf.org)
