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.
Undervisa engelska på engelska : Ett sätt att göra målspråket till arbetsspråk
High school students of today frequently come into contact with the English language throughradio and television. Many students even manage to read instruction manuals and understandhow technical devices work, such as, for example, computer games. However, most teachersunderestimate their students? ability and persist in using Swedish to explain how the Englishlanguage works. I have analysed how high school students manage when they take an Englishgrammar test in English.
Nivågruppering i grundskolans tidigare år : Hur och varför används den i matematikundervisningen
The aim of this essay is to examine why and how three teachers who work in elementary classes choose to use ability grouping during math lessons and what they think of ability grouping as a method to individualize the activities according to the pupil?s needs.I chose one main question for this study that is the following:What is the teacher?s point of view and experience of ability grouping in teaching mathematics?And three sub-questions:What are the motives behind the choice of ability grouping?What are the advantages of ability grouping?What are the disadvantages of ability grouping?In order to be able to answer my questions, I used the qualitative method. I interviewed three teachers who work in the elementary classes (First to fifth grade) to find out what they think about ability grouping and how it is experienced in mathematic teaching.The result shows that the common thing between these three teachers is that they don?t use ability grouping as the only teaching method. They all agree that the whole class teaching has many benefits for the pupils.
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.
Beslutsfattande och uppmärksamhet : Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi
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.
Förhållandet mellan barns populära status, individuella bearbetningsstil och arbetsminneskapacitet
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..
Vad ligger till grund för användares relevansbedömningar?: En litteraturundersökning
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.
Föräldrars upplevelser av att förlora ett barn i cancer
It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.
Boka en bibliotekarie - en studie i förmedlad informationssökning
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.
KBT och mindfulness i gruppinterventioner för insomni: en randomiserad, kontrollerad studie
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.
Ämneshantering hos flerspråkiga med Alzheimers sjukdom
In previous studies there has been indications that multilingualism has a delaying effect of the onset of dementia and damage on cognitive abilities (Bialystok et al., 2007; De Bot & Makoni, 2005, s. 58). Cognitive abilities refers to memory, attention, language, abstract thinking and understandings among other things (Läkemedelsverket). Other studies have seen that individuals with Alzheimer's disease (Swedish abbreviation AS from here on) have difficulties with managing a conversation (Hyltenstam & Stroud 1989). This study aims to describe the topic treatment in bilingual individuals with AS and compare their different languages.
I havet av siffror och bokstäver : En studie om matematik- och lässvårigheter hos barn i andra klass

KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?
Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.
