Measurement of the galvanic skin response during repeated stimulus
Fabík, Vojtěch ; Chmelař, Milan (referee) ; Ronzhina, Marina (advisor)
The aim of this work was introducing with the metods of analysis of galvanic skin response. The protocol for measurement of galvanic skin response during repeate stimulus was developed. Several stimulus were included in study. Then the program withgraphical user interface for analysis selected parameters was created in Matlab. Effect of habituation on repeated answers on the stimulus was described. Habituation was analized using parameters derived from electrical skin response.

Neurální habituace statických reklam v homo- a heterogenním video-prostředí.
VOLCHKOV, Ivan
This bachelor thesis focuses on theoretical elaboration and empirical research of the topic of habituation and perception of static advertisements in the cyberspace during video perception. The theoretical part contains a summary of the theory and research of habituation, perception of advertisements, and visual perception, as well as the theoretical basis of electroencephalography. The empirical part describes the intention, design, implementation, results of the research and their discussion. The between-subject experimental design is constructed to mimic real cyberspace, where advertisements become noise and distractions to the Internet users. The study aims to measure the brain's habituation response to repeated advertisement presentation while viewing educational videos based on following biophysical signals (using electroencephalography), i.e., to determine how the brain learns to get used to or respond to advertising stimuli during educational video streaming and whether there is a difference in brain reaction to homo- and heterogeneous advertising stimuli. A new experimental paradigm was created for this research. 18 participants took part in the research, randomly divided into three groups: two experimental groups and one control group. 15 participants' data proceeded to the final analysis, due to technical deficiencies of signal processing. The analysis was performed using the following EEG methods: Event-Related Potentials, Event-Related Spectral Perturbation, and Power Spectral Analysis. The results indicate that homogeneous advertisements are less disruptive to the fluency of perception of the video viewer than heterogeneous ones, but may require more prominent differentiation.

The influence of status epilepticus (SE) in postnatal development early phase on laboratory rat psychomotor development
Boťchová, Lenka ; Kubová, Hana (advisor) ; Mareš, Pavel (referee)
Bibliografická identifikace v angličtině Author's first name and surname: Lenka Boťchová, BA Title of the master thesis: Does status epilepticus during early postnatal period influence laboratory rat psychomotor development? Department: Department of Rehabilitation and Exercise Medicine Supervisor: doc. PharmDr. H. Kubová, DrSc. The year of presentation: 2013 Abstract: The purpose of this study is to evaluate the influence of status epilepticus (SE) in postnatal development early phase on laboratory rat psychomotor development. Experimentally caused (SE) is the most common mode of epileptogenesis, which is the process leading to the epilepsy creation, and typical comorbidities. The influence of the early SE was studied when using lithium/pilocarpine model of SE induced on 12 days old rat cubs, which were repeatedly exposed to the "open field" test until 32nd day of their lives that means until the puberty beginning. The evaluation is focused on cognition and overall locomotion changes and anxiety demonstrations. The results show that in short periods after SE (up to 1 month) the cognitive functions regarding the habituation disorder are not worsened. However, hyperactivity short-term disposition and worse adaptability to experimental conditions due to animal anxiety increase were detected. Motor skills of...

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...

The development of an expression of personality traits: the common vole (\kur{Microtus arvalis}) study
URBÁNKOVÁ, Gabriela
The aim of this study was investigate the development of behaviour of common vole in usually used personality test - Open Field test. This study also used a new behavioural approach ? behavioural reaction norms - to investigate the relationship among personality traits, behavioural plasticity and body weight and chosen social characteristic. There were found the effects of adult body weight and litter size on individual behavioural plasticity and also the negative correlation between personality traits and behavioural plasticity, signaling the different level of habituation dependent on personality traits.
