Early ontogenesis of time percepction
Dörflová, Kateřina ; Nekovářová, Tereza (advisor) ; Nikolai, Tomáš (referee)
This work focuses on the topic of time perception, particular emphasis is placed on interval timing. Significant part of this work is oriented toward early ontogenesis of time perception, specifically toward human perception of time from the developmental perspective. Fundamental approaches relevant for current research in the field of time perception are represented in this work, especially from the psychological perspective. The work presents comprehensive view on the current state of knowledge concerning mechanisms of time perception and its function. Emphasis is placed on existing research of interval timing and related variables playing essential role in timing. Current knowledge in the field of the development of time perception is compared with the concept of time perception and its development in context of Jean Piaget's popular theory of cognitive development. KEYWORDS Time, time perception, interval timing, human ontogenesis

Interval Timing and Emotional Modulation
Šafránková, Kristýna ; Nekovářová, Tereza (advisor) ; Telenský, Petr (referee)
This bachelor thesis focuses on time perception, a field of study pursued extensively by psy- chologists, neuroscientists, and cognitive linguistic researchers. More specifically, this paper will examine the issue of "interval timing" (i.e. an individual's ability to perceive time intervals in seconds or minutes). Time perception is influenced by several factors, of which emotional modulation has been postulated as the most crucial. Examining the physiological mechanisms of emotional modulation and pacemaker-accumulator, the striatal model of time perception along with its role in emotional modulation form the contributions of this thesis. Key words: interval timing, dopamine, emotions, the striatal beat-frequency model

Animal model of schizophrenia and time-space integration in the role of AAPA
Janďourková, Pavla ; Nekovářová, Tereza (advisor) ; Valeš, Karel (referee)
Temporal and spatial cognition constitute basic elements of the cognitive function. Both of these competences are important for the individual's orientation and survival and there are likely to be different interactions between them. Perception of time, unlike spatial navigation and memory, is less explored. Impairments of interval timing occur in many neurodegenera- tive and neuropsychiatric disorders. According to current studies it is evident that timing is impaired even in patients with schizophrenia, but the results are still ambiguous. The aim of our work was to test the AAPA task in the time-place integration in the ani- mal model of schizophrenia. In the future, it could help to clarify the impairments of the time perception in patients with schizophrenia. In contrast to the classic AAPA task, our version included alternating of phases of light and darkness. The assumption of the experiment was that the solution of the task by rats in the dark is more dependent on the timing strategy than the solution of the task during the light, which is dependent on the spatial orientation. In the first phase of the experiment, the rats adopted both strategies - spatial (during the light phase of the session) and timing (during the dark phase). In the next phase of the experiment, we tested the animal...

Interval timing and spatio-temporal integration
Sedláček, Jan ; Stuchlík, Aleš (advisor) ; Telenský, Petr (referee)
Perception of time-space, its subsequent storage and eventual recall is essential for survivor of the most, currently living organisms. In the higher vertebrates, this process is part of the declarative memory. This work will mainly focus on description of spatio-temporal interaction of these engrams in hippocampus mediated by place cells and newly discovered time cells. This work will also mention with that connected importance and function of time perception. At the end there are described timing strategies that might be acquired by subjects in behavioral tasks.
