Ontogenesis of episodic memory in preschool children
Píšová, Martina ; Nekovářová, Tereza (advisor) ; Petrásek, Tomáš (referee)
Episodic memory enables us to remember and recall life events from the past. Episodic memory is a specific type of long-term declarative memory, which undergoes changes in ontogeny. To examinate of episodic memory, "episodic-like memory model", was developed. This model focuses on three basic components of episodic memory: "What happened", "Where did it happen" and "When did it happen". The aim of this diploma thesis is to develop and to validate of particular tests of episodic memory with consideration for their feasibility for preschool children. In order to study episodic memory we used an "episodic-like memory model" and experiments which focused on: children's verbal ability, differentiation of two perspectives during remembering of events and timing memories on an autobiographical axis. We aimed to inspect the effect of age on performance in these tests, possible links between performance in these experiments and the effect of level and the three components of episodic memory on number of errors made. In our dataset we found a significant effect of the age of children in Sentence repetition test and in test of Object collection in the virtual house, in the same test we found a effect of the level on number of errors. We also found a significant correlation between correct responses in verbal...

Abstract tasks in birds - spatial vs non-spatial tasks
Janská, Iveta ; Landová, Eva (advisor) ; Vlček, Kamil (referee)
The aim of this thesis is to compare spatial cognitive tasks (radial maze and analogs, geometry and features) and non-spatial abstract cognitive task (concept formation and categorization, transitive inference) in birds. Because each of tasks have different testing methods they are compared according to method types in separate thematic groups, which are discussed each other. The extension of this thesis on theories derived from human psychology such as self-recognition, episodic-like memory, and theory of mind.

Neurobiological Correlates of Episodic-like Memory
Oravcová, Ivana ; Nekovářová, Tereza (advisor) ; Stuchlík, Aleš (referee)
Declarative memory is characterized as a conscious, explicit memory. Declarative memory consists of two essential systems, semantic memory and episodic memory. Episodic memory enables us to recall specific past events. A simplified model, so called Episodic-like memory is often used to study episodic memory mechanisms. According to this model, all events are stored in a contextual framework consisting of three basic components: identity of the object ('what' happened), temporal information ('when' it occurred) and spatial information ('where' did it happen). This type of memory is testable not only in humans but also in animal models. Aim of this diploma thesis is to study the neuronal substrate of individual components of episodic memory in healthy volunteers by means of functional magnetic resonance imaging (fMRI) and ecologically valid tasks designed in virtual reality environment. Results obtained in the fMRI paradigm show that apart from common neuronal substrate of episodic memory, additional brain structures are responsible for recollection of individual components of the episodic-like memory. Behavioral data indicate that the demands of the recollection of individual components is not equivalent. Additional analyses with parcellation of the brain to individual structures and consecutive...

Episodic-like memory changes during aging
Čechová, Kateřina ; Vlček, Kamil (advisor) ; Stehlík, Luděk (referee)
The Diploma thesis is concerned with the human episodic-like memory and its changes during the course of healthy ageing. Episodic memory represents a memory of specific events and their spatiotemporal relations, involving conscious retrieval and mental time travel. As a testable analogy in animals, a concept of episodic-like memory has been suggested and defined as a memory of spatiotemporal location of a certain event in the past ("what-where-when"). Firstly, we focused on a methodological comparison of standard psychological tests of episodic memory and a novel non-verbal computer-based Episodic-Like Memory Test (EMT) with several variants of varying difficulty, capable of discerning the memory for pictures, their sequence and position (Vlček et al., 2009). The second goal of our study was to demonstrate the applicability of the concept of episodic-like memory ("what- where-when") as a model in the testing of human episodic memory. Compared with other tests of episodic memory, EMT test does not depend on the verbalization of content. Contrasting the results obtained from EMT and other standard tests was, therefore, of interest. The results from the EMT test were compared across three age cohorts (N = 58; young, middle-aged, aged) of healthy volunteers. In the spatial domain of episodic-like...

Episodic like memory in nonhuman animals
Gálik, Michal ; Landová, Eva (advisor) ; Vlček, Kamil (referee)
Episodic memory refers to an ability that allows a person to mentally re-enact past events from his own life. This capacity was long considered to be uniquely human. The best evidence of this ability in humans is subjective consciousness, which accompanies episodic recollection. For this reason, it is particularly difficult to study such cognitive ability in other animal species. However, there is some indirect evidence showing that animals could possess the ability of episodic memory to some degree. This bachelor thesis summarizes recent knowledge about episodic memory, provides an overview of specific studies in different animal taxons and compares the methodologies used by various authors to demonstrate episodic memory in animals. It focuses mainly on birds, rodents and primates. KEYWORDS : Episodic memory, Episodic-like memory, Hippocampus, Cognitive ability, Animal model
