Connection between sleep and memory consolidation in elderly people with and without cognitive impairment
Krejčová, Marie ; Kulišťák, Petr (advisor) ; Panenková, Erika (referee)
This thesis focuses on a connection between sleep and memory consolidation in people older than 55 years with and without cognitive impairment. The theoretical part discusses how sleep changes during aging and what influence these changes could have on cognitive functions (memory etc.). In a long-term perspective, sleep could play a role in a gradual decline of cognitive functions. Thus, modern researches focus on multifactorial causes of neurodegenerative diseases. These studies include those that examine a relationship between quality of sleep and cognitive functions. For better understanding this topic, these researches are described in this paper as well. In the second part of the thesis, a research design is outlined, which could clarify the relationship. It is examined by comparing memory consolidation of people older than 55 years with and without cognitive impairment. It is considered by amount of remembered material during a day/night. The study might discover, whether sleep disorders could play a role in the decline of cognitive functions during aging.
Means of cognitive screening methods in the elderly
Bartošová, Martina ; Panenková, Erika (advisor) ; Kulišťák, Petr (referee)
This Bachelor thesis deals with cognitive functions of the elderly and the options of screening examination of these functions. The goal of this thesis is to describe and compare the most used screening tests in the Czech Republic and their practical aspects. The literary overview part describes the current elderly population and shortly characterizes cognitive functions with focus on their changes due to normal ageing. It then goes on to differentiate between screening and complex neuropsychological examination and shows an overview of selected screening tests of cognition and possibilities of their use. In the second part a research is designed, which should verify the relationship between the level and the type of achieved education of the elderly, their career choice and the results of selected screening cognition tests. The goal of the research is to shine a light on the issue of not accounting for local aspects while using education bound norms in current elderly population in the Czech Republic.

Visual Memory in the perception of prototypical scenes
Děchtěrenko, Filip ; Lukavský, Jiří (advisor) ; Kulišťák, Petr (referee)
To be able to operate in the world around us, we need to store visual information for further processing. Since we are able to memorize a vast array of visual scenes (photographs of the outside world), it is still an open question of how we represent these scenes in memory. Research shows that perception and memory for visual scenes is a complex problem that requires contribution from many subfields of vision science. In this work we focused on the visual scene memory on the creation of perceptual prototypes. Using convolutional neural networks, we defined the similarity of scenes in the scene space, which we used in two experiments. In the first experiment, we validated this space using a paradigm for detecting an odd scene. In the second experiment, using the Deese-Roediger-McDermott paradigm, we verified the creation of false memories and thus visual prototypes. The results show that people intuitively understand the scene space (Experiment 1) and that a visual prototype is created even in the case of the complex stimuli such as scenes. The results have wide application either for machine evaluation of image similarities or for visual memory research.
The Role of Music in Emotion Regulation
Jirásková, Veronika ; Kulišťák, Petr (advisor) ; Šípek, Jiří (referee)
The thesis presents the concept of emotion regulation in connection with music and its listening. It deals with the theoretical definition of emotions and in the context of emotion regulation supports the process model following the theory of appraisal. For further description we choose reappraisal strategy, with which is also worked in this research study in the Emotion Regulation Questionnaire (ERQ), which analyses 215 responses from 215 respondents by collecting online study data and finding that three variables predict this strategy, namely discharge (VE), entertainment (Z) and revival (R) of the used questionnaire Music in Mood Regulation (MMR). Furthermore, a negative correlation was found in the strategy of suppression with life satisfaction and a positive correlation of reappraisal with life satisfaction. The thesis by its research outcomes supports connection of ER concept together with mood regulation by music.

Hrešková, Lucia ; Krámská, Lenka (advisor) ; Kulišťák, Petr (referee) ; Praško Pavlov, Ján (referee)
Neuropsychological assessment and psychoeducation of patients diagnosed with psychogenic nonepileptic seizures (PNES) Mgr. Lucia Hrešková Tutor: Assoc. Prof. Lenka Krámská, Ph.D. Abstract: The term psychogenic non-epileptic seizures (PNES) refers to a conversion disorder (300.11) imitating epileptic seizures that are psychological etiology (DSM-5). Neuropsychological assessment including personality profile and mood status is an integral part of the diagnosis and treatment of PNES. The main treatment is psychotherapy. In the theoretical part of this research project, we have processed psychoeducation guide for clinical psychologists and psychotherapists working with patients diagnosed with PNES, based on recommended standards (Myers, 2014; LaFrance & Wincze, 2015; Reiter et al., 2015) and long-term clinical experiences with these patients (in particular Assoc. Prof. Lenka Kramska, Ph.D.). The purpose of our research project was to assess the presence of maladaptive emotional regulation in the profile of patients diagnosed with PNES (N = 51) compared to healthy populations (N = 51), through self-report questionnaires Affective Style Questionnaire (ASQ) and Difficulty in Emotion Regulation Scale (DERS). The results of our research show a significantly higher level of maladaptive emotional regulation in the...
Emotional disorders as a consequence of brain damage and possibilites of psychotherapy
Krejčová, Svatava ; Kulišťák, Petr (advisor) ; Jelínek, Jakub (referee)
This Bachelor's thesis describes in short manner types of brain lesions and with regard to the mechanism and location of the lesions summarizes findings/conclusions of studies aimed on types and character of emotional disorders such as depression, anxiety, emotional instability, increased irritability and emotional flattening caused by such lesions. It takes into an account the practical aspects of the treatment of the patients with such conditions such as psychotherapy or intervention programs. In research part, the thesis proposes a form of intervention program for patients inspired by current literature focused on awareness, communication and regulation of emotion.

Embodiment in social cognition and theory of mind
Takáčová, Bibiana ; Kulišťák, Petr (advisor) ; Kaplan, Cyril (referee)
The bachelor thesis deals with the concept of embodied cognition, which understands perception and action as a functional and indivisible whole. Instead of needing mental representations, it offers a dynamic and interactive model of circular exchange with the environment. In a number of examples, it describes how it is possible that the interaction and behavior of an organism may not depend on complex calculations that, according to a traditional model, are placed in the brain but how the body itself and its adaptation can be sufficient for these processes. In this manner, it turns to work on social cognition and her current broader interpretation framework how we create beliefs about the states of other people, that is, the theory of mind. Based on the simulation theory, it suggests research that aims to determine whether lower-level processes such as empathy will be constructive in solving more complex tasks of one of the theory of mind tests - the Faux pas test.

Rehabilitation of prospective memory in patients after brain injury
Novotná, Dagmar ; Kulišťák, Petr (advisor) ; Krámská, Lenka (referee)
Prospective memory is very important for everyday life of all people. Patients with brain injury often have problems with their prospective memory, the ability to remember what they would like to do in the future and to remember that intention at the right time. Rehabilitation and prospective memory training differ in the literature as well as its efficacy results. The thesis deals with the issues of prospective memory and its rehabilitation with people with acquired brain injury. The aim of this work is to create a summary of existing knowledge about prospective memory, design and implementation of prospective memory training program with patiens with acquired brain injury. The theoretical part of the thesis summarizes basic information about prospective memory, its division and overview of theories. An important part of the thesis is an overview of methods for prospective memory diagnostics. The end of the theoretical part of thesis is about different ways of rehabilitation prospective memory. The empirical part presents the theoretical basis for the cognitive rehabilitation. On this basis a prospective memory training was developed and subsequently tested with patiens with acquired brain injury. The thesis also includes a detailed manual for prospective memory training. The effectivness of the...
Visual Memory of Fragmented Scenes - Role of Detail and Extrapolation
Koppová, Kateřina ; Lukavský, Jiří (advisor) ; Kulišťák, Petr (referee)
Every day we are exposed to huge amounts of visual stimuli (scenes). However, i tis not yet clear how accurately these scenes are stored and remembered, and what is the role of detail relative to the memory for the whole image. More specifically, to what extent the details are remembered and to what extent we extrapolate the unseen content from the presented details. We used fragmented scenes (broken to 4x4 grids) to investigate this question. Fragmented scenes were composed of three different theme categories (indoor, natural, man-made), each with different number of presented patches (3, 5 and 8). Our main research question is, whether there is any relationship between the number of presented patches and the ability to recognize which patches were presented and which were not (but still patches from the same photograph). In analysis we focus on Signal Detection Theory characteristics, mainly memory sensitivity (d') and bias. We run two experiments and in both the highest scores for (d') were for 3 patches (Exp.1: d'(n3) = 0,67; Exp.2: d'(n3) = 0,66) with bias towards negative answers (Exp.1: c(n3) = 0,27; Exp.2: c(n3) = 0,16). For 5 and 8 patches the (d') was lower (Exp.1: d'(n5) = 0,35; d'(n8) = 0,34; Exp.2: d'(n5) = 0,39; d'(n8) = 0,41) and in the same time bias was towards positive answers...
