Bakgrundsbrusets effekt på kognitiv prestation samt skapandet av falska minnen : Om bullrets inverkan i öppna kontorsmiljöer

This study aimed to explore how 31 collage students' cognitive performance and their ability to create false memories were affected by the exposure of an extraneous background noise. The studies main hypotheses were based on previous research on how extraneous noise affect the cognitive ability and the creation of false memories: 1) that an extraneous background noise increases the ability to create false memories, 2) that an extraneous background noise impairs the learning of cognitive information, 3) that an extraneous background noise contributes to an increased representation of fictional words, 4) that an extraneous background noise impedes the ability to understand speech . The results showed a tendency in which false memories increased in the condition without background noise, a result which goes in the opposite direction of the hypothesis. Furthermore, the result supported the hypothesis that the extraneous background noise impairs the learning of cognitive information. The results also showed that there was no effect between the conditions regarding the representation of fictional information.

Jag läser och förstår det intressanta : Tillgänglig, förståelig och intressant information för personer med lindrig till måttlig utvecklingsstörning. Information på FUB:s webbplats, som skrift i samspråk med bild.

Most of the information online is difficult for people with cognitive disabilities to understand and assimilate. In this project I have had the expectation that this is possible to change. In cooperation with FUB, a Swedish organization working for people with cognitive disabilities, I have studied how to adapt content, pictures and writing to persons with the levels of mild to moderate cognitive disabilities. I have also taken the perspective ?design for all?, which means that you adapt a design for the weakest persons in the society to make it work for everyone.The purpose of my work is to study how to create a web text where content, writing and pictures are incorporated.To examine how to do this I have conducted qualitative interviews in which I have let the informants look at and read four different texts.

Muskuloskeletala besvär bland kvinnlig tandvårdspersonal : En kvantitativ studie

The purpose of this study was to investigate whether cannabis use can affect cognitive functions. The method that was chosen to answer the purpose of the study was a general literature review. Article search occurred in the databases PsycINFO and PubMed. Nine articles were selected based on the study?s inclusion criteria.

En studie om lärarstudenters informationssökning

The main purpose of this Master?s thesis is to contribute to anincreased understanding of student teacher?s informationseeking for their studies. The role of cognitive authorities andapproaches to the critical evaluation of sources are taken intoaccount as well as what student experiences of informationseeking imply for their future profession. The study takes asociocultural perspective and the empirical material is based oninterviews with six student teachers at the end of theireducation. The interviews have been analysed with a departurepoint in the research questions to the following themes; seekingand finding information, critical evaluation of sources and,analysing and using information.The major findings concern the teacher students? emphasis onthe importance of the critical evaluation of sources and theirscepticism towards Internet use, both for their own studies aswell as for their future pupils.

Personer med utmattningssyndrom: : Finns det ett samband mellan subjektiv och objektiv kognition?

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.

Svensk asylpolitik : En studie kring styrning och långa handläggningstider på Migrationsverket

The Swedish Migration Board has during a long time had problems with long processing times for persons that apply for asylum. The government has set targets that investigation should not exceed 6 months although it is done in almost 70% of cases.The study's aim has been to examine if steering can be linked together to long processing times and, if so, explain why. The intention has not been to provide a comprehensive picture of the problem but has defined itself to ensure steering impact. The study has been carried out by studying relevant governing documents, previous research and by interviews with administrators and decision-makers in two of the Migration Board asylum units.The analyses of the study show that a combination of inadequate steering and inadequate resources have contributed to aggravate the implementation, which has lead to long processing times..

En dag på arbetet: sjuksköterskeprofessionens informationspraktik

The aim of this thesis is to create an understanding of nurses' information practices. To be able to search, find, use and critically evaluate information is important, not just during studies, but also in professional life. This study is intended to deepen our understanding of nurses ' information literacy in a workplace context.The main questions are: What information do nurses need on a daily basis and how do they experience information activities? What factors determine the sources they use? Do information practices vary in the workplace? Do nurses? professional experiences impact on their information practices? Nine nurses were interviewed using semi-structured interviews. The interviews have been analysed through a hermeneutic approach.

Biblioteks- och informationsvetenskap som kunskapsområde En bibliometrisk studie.

The objective of the study is to map the cognitive structure of Library and Information Science, using a quantitative, bibliometric method. This empirical study shows how co-citation analysis combined with word-frequency analysis can be used to describe the subject content of the field. The research questions to be answered are: -Which clusters of authors can be identified? -How can these clusters be described in respect of their subject content, if the descriptors associated with the authors in the clusters are counted? The results show that the cognitive structure of Library and Information Science can be described by 13 clusters of authors, where each cluster is representing a specific aspect of the subject- domain. For the description of the subject content of the clusters, descriptors DE of the LISA database have been used..

Utveckling av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning i ett ettårsperspektiv

The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year.

Etableringssamtal

Abstract I vår studie har vi intervjuat arbetsförmedlare som arbetar med etableringssamtal på Arbetsförmedlingen. Syftet med vår studie var att undersöka hur etableringssamtal går till och vilka faktorer påverkar samtalets utgång. Med hjälp av etableringssamtal så skall de nyanlända etablera sig snabbare och denna insats är frivillig. Vi genomförde kvalitativa forskningsintervjuer med åtta arbetsförmedlare som arbetar på etableringskontoret och som utför etableringssamtal. Resultatet analyserades utifrån samtalsmodellen The Skilled Helper av Gerard Egan, Vance Peavys konstruktivistiska vägledningsmodell samt begreppet gap som är taget från Cognitive information processing teori.

Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare

The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.

Digitizing the Parthenon using 3D Scanning : Managing Huge Datasets

Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.

?Jag tänker inte sitta hemma och sticka? ? En studie av sex nyblivna pensionärers informationsbehov och biblioteksvanor.

This study is about information needs and library habits among newly retired people. The purpose of this master thesis is to examine the affective and cognitive needs that come with retirement. In what way do the information needs of this group change due to retirement? In order to answer this question we make use of two theoretical models; Role theory and Wilson?s model of information needs. When it comes to library habits, we use Andersson and Skot-Hansens model to examine how newly retired people use the library now and how they could use it on basis of their needs in their new role.

Aktivitens betydelse för åldersrelaterad kognitiv försämring

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..

Implementation av ett interface till Emotiv Epoc

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.
