The thesis also focuses on the problematic of memory consolidation and the method of targeted memory reactivation. The thesis also aims to design a research project that uses findings from the theoretical part. The aim of the research design is to test the effectiveness of targeted memory reactivation for patients with PTSD and to discuss the potential benefits and limitations of such intervention.

The Relationship between Sleep and Positive Emotion Regulation in Healthy Adults
Uškrtová, Johana ; Janků, Karolina (advisor) ; Urban, Kamila (referee)
This thesis concerns itself with the relationship between sleep and emotional regulation. Sleep is a significant state that plays a role in both physical and mental health. This thesis especially deals with the regulation of two positive self-conscious emotions, authentic and hubristic pride, in adult non-clinical population. The theoretical part introduces basic theories, knowledge and relevant research connecting sleep and emotional regulation. Through quantitative research with repeated measurements and multiple groups, the empirical part examines the relationship between sleep and the regulation of authentic pride, hubristic pride, and potential changes in the valency, arousal and dominance of the emotion. The emotion was induced by positive feedback to the participants' performance in cognitive tests. The analysis of variance (ANOVA) showed that the participants who were asleep between expositions marked the emotional intensity as significantly lower than those who stayed awake (F(1,34) = 5,99, p = 0,020). The size of the effect was large (ηšp = 0,150). The other variables did not show a significant interaction between the measurement and group. These findings may help with further studies of sleep and emotional regulation, especially regulation of positive self-conscious emotions. Key words:...

Effect of Cognitive Behavioral Therapy on Emotional Regulation in Patients with Insomnia
Soukupová, Linda ; Janků, Karolina (advisor) ; Zernerová, Lucie (referee)
This diploma thesis firstly introduces the topic of insomnia, models of its aetiology and treatment, with particular emphasis on emotional regulation. Main aim of the empirical part is to assess the effect of cognitive-behavioural therapy on emotional regulation in adult patients dealing with insomnia, because this psychological construct has been mostly overlooked in the context of treatment. The present pilot study observes the level of subjectively reported difficulties in emotional regulation in a group of insomniacs before and after undergoing psychotherapeutic intervention in comparison with control group with treatment as usual. The results show no significant effect of cognitive-behavioural therapy on reduction of difficulties in emotional regulation. Limits and implication of this study for future research are discussed. Key words: insomnia; cognitive-behavioural therapy; emotional regulation

Objective and subjective characteristics of sleep in chronic insomnia
Janků, Karolina ; Kopřivová, Jana (advisor) ; Papežová, Hana (referee) ; Šonka, Karel (referee)
Background: Insomnia is one of the most prevalent sleep disorders, negatively impacting the quality of life and increasing the risk of other health problems. Many patients with insomnia underestimate their sleep quantity compared to objective sleep measures. This objective and subjective sleep discrepancy (sleep misperception) occurs in different insomnia subtypes as well as in insomnia with a comorbid psychiatric disorder. Although previous research suggests that the sleep discrepancy reflects specific objective sleep alterations, the results of studies are inconsistent. Moreover, its relation to psychiatric comorbidities is not clear, as well as its role in the insomnia treatment. Aims: The theoretical part of the present thesis aimed to provide an overview of the recent research on sleep discrepancy in insomnia. The experimental part consists of four studies with the following goals: (1) to explore sleep electroencephalographic (EEG) correlates of sleep discrepancy in insomnia patients (Study 1); (2) to assess the association between sleep discrepancy and psychopathology (Study 2); (3) to examine changes of sleep discrepancy during and after the cognitive behavioural therapy for insomnia (CBT-I; Study 3); (4) to assess whether the additional chronotherapeutic tool can enhance the effect of CBT-I...
