Conservatism and liberalism - an outdated concept?
Pour, Marek ; Vranka, Marek (advisor) ; Lukavský, Jiří (referee)
Conservatism and liberalism in american psychological reasearch is mostly described as unidimensional scale which clearly divides ideology into two opposite ideological standpoints. However, current relevant studies show that unidimensional approach to study ideology is overly simplified. Linking ideological orientation and personal traits seem to bring about contradicting results. In a similar way, relevant psychological instruments for measuring conservatism seem to measure two relatively independent aspects of conservatism. It is apparent mostly from large population studies, that ideological orientation is more complex than it may appear. Specific agendas stemming from their respective ideological directions are for a large part of population relatively uncorrelated with their overall ideological self- identification. Multidimensional models of conservatism and liberalism using at least social and economic agenda therefore seem as a more useful way to describe political orientation for most of the population. Empirical part of the study proposes a partial replication of two relevant studies to test a thesis of similar multidimensionality of the left-right ideological orientation scale in czech population. This could at the same time provide a relevant american-czech comparison.
Activity of V1 neurons after presentation of novel class of stimuli: comparision with experimental data
Machálek, Jiří ; Lukavský, Jiří (referee) ; Brom, Cyril (advisor)
Neurons in visual cortex areas V1 and V2 are selective to the shape of stimulus. Almost all present theories and models assume that variability to the shape of stimuli to which the neurons are selective is very low - preferred shapes are typically only bars and edges. However recent study (Hegdé and Van Essen) showed that is not true { single neurons prefer wide range of shapes. This work replicates the study in current computational models of cortical areas V1 and V2 (for example LISSOM) and compares results with experimental data. It shows that examined models develope neurons preferring these complex shapes rarely or just for a part of stimuli set.
Conservation of quantity in preschool and younger school age
Hejlíková, Tereza ; Lukavský, Jiří (referee) ; Klusák, Miroslav (advisor)
The aim of this thesis was to try to repeat the well-known experiment of Jean Piaget, which investigates the process of acquiring the notion of conservation of quantity and hence to reproduce his theory by examining present-day population of children. At the same time we have tried to question the theory and the answers were supposed to create kind of alternative theory and add a few new findings to it. At first we have studied relevant parts of Piaget's monography called The Child's Conception of Number (Piaget, 1997) so that we could understand his conclusions. We adopted his own design of experiment which was then slightly modificated in order to provide a space for our own experimental hypothesis. The experiment was carried out with the help of sixteen children in the age of 4 to 7,5 years. We used qualitative analysis to get our own interpretation of obtained data in the same way Piaget did in the past, except that we have also focused on particular childrens' reactions that led us to the answer to our experimental questions. In the last part of the thesis we have confronted our findings with those of Piaget and thus we have demonstrated a possibility of expanding Piaget's theory as well as taking a different point of view of it. As we could not identify (based on our own analysis) with all of Piaget's...
Space maps for human-like agents
Kotrla, Jakub ; Lukavský, Jiří (referee) ; Brom, Cyril (advisor)
The goal of this thesis is to create model of spatial map for human-like agent living in virtual world. The model will increase agent's ability to mimic some aspects of human behaviour. These includes inaccuracy of spatial memories, gradual learning and forgetting. In thesis we introduce model based on results of research of places cells. Spatial map consists of nodes that are at rst distributed uniformly in the world. Virtual agent wanders through world and perceive surrounding objects. Spatial map gradually changes distribution of nodes in world according to agent's perceptions. Model is able to recognize areas with higher count of objects and create concepts of places. Algorithms of model are described including their time complexity. Model was implemented in Python and tested. At the end of thesis we present several possible extensions and future work.
Physiological correlates and semantic distances in word association test
Lukavský, Jiří ; Šikl, Radovan (advisor) ; Urbánek, Tomáš (referee) ; Kremláček, Jan (referee)
The project is focused on the physiological reactions during Word Association Test (WAT). The author tests the hypothesis originally proposed by Slechta (2002b) about separable cognitive and emotional workload, where · the cognitive workloads manifests in reaction times (RT) and emotional work- load in physiological reactions (e.g. electrodermal activity). The hypotheses were tested on the sample of young healthy adults (N=80), with protocol consisting of 40 Czech nouns. The stimuli varied in their level of concrete- ness and their emotional valence. During the experiment RTs, electrodermal activity (EDA) and pupillary responses (PR) were measured. Data support the original ndings that RTs and EDA reactions reřect in WAT di®erent situation requirements: cognitive workload and emotional workload, respectively. The e®ect of cognitive workload is larger and mani- fests also in EDA reactions, while EDA demonstrated the best sensitivity to emotional valence condition from all employed methods (RTs, EDA, pupil- lary reactions). The e®ects are unfortunatelly too small to allow a reliable classication of responses. The e®ects of other factors (subjective valence, corpus frequency of re- sponses, semantic proximity measured with Semantic Selection Test) were investigated, but even when signicant correlations were...
Stereotypes about aging population
Štěpánková, H. ; Lukavský, Jiří
First, the paper presents stereotypes about aging and its impact on the aging population. It is indisputable that these stereotypes, no matter whether they are positive or negative, have an influence on psychological as well as physical health. Second, the paper informs about memory training programme for seniors and the part of research focused on subjectively perceived changes in relevant aspects. Research findings are discussed in terms of possibilities to influence the stereotypes about the aging population.
Může být citlivost ke zrakovým klamům ovlivněna dlouhodobým pobytem v uzavřeném prostředí?
Šimeček, Michal ; Šikl, Radovan ; Lukavský, Jiří
In the paper, we consider the influence of long-term isolation stay on visual space perception. Six crewmembers of the ground-based experiment simulating manned flight to Mars was closed for three and half months to the facility restricting view to no more than a few meters distances. We expect that such restriction would impair the observer’s ability to utilize information from perspective, which among others will manifest itself in the observer’s changed susceptibility to geometrical illusions. By the time of KUZ IX conference, the data from all sessions are still not available.
