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.
Hundfoder mot hjärnans åldrande ? kan det fungera?
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.
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.
Luftvärnets verkanssystem i Utlandstjänst
This paper aims to analyze if ground based air defence of the Swedish Defence Forces is sufficiently equipped to protect units serving abroad. The Swedish ground based airdefece has its roots in the era of the cold war but the focus of Swedish Defence Forces has shifted from defending Swedish territory to peace keeping and peace enforcement in foreign countries. First I will take a look at the base factors for ground based air defence units serving in a peace keeping or enforcing mission and then use this to define what abilities you would like to have in a ground based air defence system. Finally I will compare these abilities whit the abilities of the ground based air defence systems that are in use whit the Swedish Defence Forces.My conclusion is that the question can´t be answered on a generel level but every mission has to be analyzed individualy.The author of this paper is Cadet Tobias Jönsson studying at the The Armed Forces Technical School to become an officer in the Swedish Defence Forces..

Får högpresterande elever den utmaning de har rätt till i skolan? : En empirisk studie baserat på lärares åsikter om arbetet med individualisering med fokus på högpresterande elever
The purpose of this study is to investigate five teachers? opinions on the work with individualization with focus on above-average pupils. I have issued four questions based on the purpose of this study: - How do these teachers define the theoretical concepts of individualization and above-average pupils? - How do the teachers reason about the concept of individualization with focus on the above-average pupils? - How do the teachers reason regarding the work with individualization in the Swedish language? - Do these teachers consider that there are difficulties to individualize the work so that it will challenge above-average pupils?The method used to conduct this study was a semi-structured qualitative interview with five teachers in primary school. The theory and the theoretical concepts this study is based on is: what defines the above- average pupils, the zone of proximal development, the concept of individualization and motivation and the importance of cognitive and non-Cognitive abilities.The study shows that the theoretical concept of above-average pupils is hard to define and it shows a difference between how the teachers choose to define it.
Undervisning för elever med särskilda matematiska förmågor : En studie om hur lärares undervisning i grundskolans tidigare år bedrivs och anpassas till elever med särskilda matematiska förmågor.
The purpose of this study is to see how some teachers in primary school creates and adapts their mathematics teaching for students with special mathematical abilities. It also aims to identify opportunities and challenges that teachers see in creating a teaching adapted to these students.In this study, qualitative interviews has been done to collect data. The interviews were conducted with five teachers who all are active in the primary school.The study results show that there is great variation in how the interviewed teachers create their mathematics teaching for students with special mathematical abilities. The use of mathematics book proved to be significant for how this adaptation took place. The result also shows that the teachers? explanations for the choice of the adaptations that they make in teaching vary.

Ingenjörpluton : Kung på en sak eller klåpare på tusen?
This essay is about the engineer platoon. The engineer platoon has many different tasks and from my own experience sometimes too many. The platoon is able to build bridges, clear mines and to perform all kinds of construction work in rural or in urban terrain.In this case study I compare goals/demands for the battalion to goal?s set up for the company and finally what effects this has on the engineer platoons abilities. The main question is, if the engineer platoon really can solve all tasks given to them in the document TOEM? Abilities such as effect, protection and movement are the bearing parts of the case study.The materials I have analyzed are mostly from documents published by The Swedish Armed Forces.
Fonologiska och kognitiva förmågor hos barn : en jämförelse mellan barn med cochleaimplantat och/eller hörapparat och normalhörande barn
Syftet med föreliggande studie var att undersöka eventuella skillnader mellan barn med cochleaimplantat (CI) och/eller hörapparat (HA) och normalhörande barn i åldrarna fem till sju år avseende fonologiska och kognitiva förmågor. I studien jämfördes resultat från elva till 44 normalhörande barn med åtta till 25 barn med CI/HA från fyra olika studier. Undersökningsmaterialet utgjordes av kortversionen av Stora fonemtestet, fonologiska representationer, TOWRE samt fem deltest ur testbatteriet SIPS. Testresultaten analyserades kvantitativt och för kortversionen av Stora Fonemtestet även kvalitativt. Resultatet visade att barnen med CI/HA generellt presterade lägre än de normalhörande barnen på test av fonologisk förmåga och fonologiskt arbetsminne, men att de låg i nivå med de normalhörande barnen avseende generellt och visuospatialt arbetsminne.
Renskötselrätten : som rättslig konstruktion
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.
