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...

Celiac disease - health consequences of the Neolithic nutrition for modern human
Polanská, Helena ; Brůžek, Jaroslav (advisor) ; Sedlak, Petr (referee)
Celiac disease is an inflammatory disorder of the intestine, which is developed by genetically susceptible individuals. For the manifestation of celiac disease is conditional consuming diet with gluten, which is a triggering factor for this illness. Gluten is contained in cereal grains of wheat, barley and rye and there was no gluten in original hunter-gatherer's diet. Cereal grains became stable part of human diet after the agicultural tradition was established, in Neolithic period. Some societes had a tradition of consuming gluten-free plants and therefore they were protected for a long time. Today celiac disease is spread worldwide, even in populations with traditional consumption of maize or rice too, and risk of the celiac disease has a relation to wheat consumption.
