Can degree of degenerative brain disease be predicted with the help of measurements of Cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s Cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of Cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in Cognitive functions vary between groups with different levels of degenerative brain disease.

ABSTRACTBackground: After general anesthesia the Cognitive ability is temporarily impaired. Cognitive recovery is necessary for the patient to be able to assimilate the information that she / he gets postoperatively. It also increases the patient safety. There are few methods to estimate and assess the patient's Cognitive recovery before and after anesthesia. The purpose of this study is to test the usefulness of the instrument PQRS and to assess the patients Cognitive recovery after anesthesia.

Research shows that people with burnout experience a high degree of impairments in a range of Cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and Cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what Cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported Cognitive problems? Third, are the self-reported Cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and Cognitive measures. The main findings suggest that activities are associated with Cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for Cognitive training of either healthy or mentally impaired subjects to increase Cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.

In recent years Cognitive training in order to improve Cognitive abilities have becomeincreasingly popular and a lot of research has been conducted within this field. The natural agingprocess has a negative effect on many of our Cognitive abilities and this relationship also has a strongconnection with hearing loss. Elderly with hearing loss is therefore a group that could benefit fromCognitive training. Objective: The purpose of this study was to investigate different types of Cognitivetraining directed towards working memory in older adults and to examine the results observedregarding efficacy of this type of training and its transfer effect. Method: A literature reviewconsisting of 17 scientific articles published between 2005-2014.

This study was conducted to investigate the relationship between perceived popularity, social information processing and working memory. With the intentions of examining popularity 209 (98 female, 111 male) children in second and fourth grade were presented with a roster of their classmates and were to nominate whom they liked and whom they disliked. To study working memory capacity a working memory test, that places demands on the participant to work both with and store the given information, was used. To examine children's Cognitive processing of empathy-provoking information a Cognitive appraisal interview was conducted. The results imply (a) that working memory increases with age, (b) that there is a weak relation between working memory capacity and popularity, and between popularity and Cognitive processing styles and (c) that there are some strong correlations between working memory and Cognitive processing styles..

The purpose of this thesis is to get an improved understanding of what the bases for relevance are, when people in real information need situations make relevance judgements. In order to meet this purpose, an investigation based on research literature is performed. Four types of relevance are investigated: topical or subject relevance, Cognitive relevance or pertinence, situational relevance or utility, and socio-Cognitive relevance. The investigation also deals with users relevance criteria identified in fourteen empirical studies, in which the users are adults and engaged in oral, textual, and multimedia information retrieval. Finally, the connections between the user criteria found and the types of relevance are discussed.

Due to better nutrition, veterinary and overall care, pet dogs? lifespan has increased. With more old dogs we see more health problems associated with age, among those Cognitive decline, leading to deficits in learning and memory, disorientation, anxiety and other altered behaviors. Cognitive decline can have severe negative impacts on the life of both dog and owner, when the dog for example forgets being housetrained or starts being awake at night. Two pet food manufacturers have developed food with specific ingredients in order to improve Cognitive functions or delay the onset of Cognitive impairment. Hill?s Pet Nutrition has developed a dog food with supplements of a broad spectrum of antioxidants and mitochondrial nutrients, aiming to diminish oxidative damage in the brain, thereby maintaining brain function and improving learning ability.

This master thesis deals with events, dynamics and problems of mediated information seeking within the context of a new information service called "Book a librarian". The study, based on a survey and interviews both in academic and public libraries and participant observations in academic libraries, has its theoretical base in the Cognitive theory of information retrieval interaction. The Cognitive view is used to throw light upon the need of an ongoing dialogue during the session in order to detect the information needs of the user and to conduct a successful retrieval of information. The communicative interaction is seen as threepart interaction between the intermediary, the user and the information system, where the current Cognitive states of all three participants are involved. The study shows that the Cognitive obstacles for a successful mediation and information retrieval are mostly connected to participants current knowledge of the subject and of the retrieval techniques.

There is strong evidence that Cognitive-behavioural therapy for insomnia (CBT-I) is effective. The aim of this study was to compare 7 group-sessions of mindfulness-based Cognitive therapy for insomnia (MBCT-I) with 3 group-sessions of CBT-I, on sleep measures and sleep related psychological processes, such as pre-sleep arousal, thought control strategies and mindfulness. Participants (N = 44; age 18-66) with long term insomnia were stratified and randomized into waiting list, MBCT-I and CBT-I. Significant improvements were seen in both groups, compared to waiting list, for instance on insomnia severity, sleep latency and restorative sleep. Small improvements on psychological processes were also found in both groups.

This master thesis concerns the relation between law and the theory of the conceptual metaphor which has developed within Cognitive linguistics. Although its main focus is abstract thinking, it also covers a wide range of aspects within Cognitive linguistics, such as the prototype theory and radial categories. In order to address this relation, three questions will be dealt with. Firstly, does the theory of the conceptual metaphor have relevance to interpretation of legal rules and contracts? Secondly, can the same theory explain why a legal rule or a contractual term has been interpreted outside of its most given area of application? Thirdly, when an interpretation is not predictable from a legal viewpoint, can such an explanation answer to that fact? Answering the first question will require a descriptive analysis of the conceptual metaphor and Cognitive linguistics.
