Procedurellt minne hos universitetsstuderande med dyslexi

Dyslexi är en form av läs- och skrivsvårighet som inte kan förklaras av t.ex. bristfällig undervisning, låg begåvning eller synproblem. Orsaken till dyslexi anses vanligen vara nedsatt förmåga av fonologiskt processande. Flera studier har dock visat att dyslexi även är förknippat med språkliga, kognitiva och motoriska svårigheter som inte kan förklaras av nedsatt förmåga av fonologiskt processande. Det procedurella minnessystemet engageras vid inlärning, processande och konsolidering av kognitiva och motoriska färdigheter.

Seriell återgivning av två-röstslistor: ord organiseras inte efter röst

AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.

Intra-individuell variabilitet i nära transfer : Om åldersrelaterade skillnader i intra-individuell variabilitet i prestation och effekten av kognitiv träning

Syftet med denna studie var att undersöka om träning av exekutiva funktioner kan påverka den intra-individuella variabiliteten (IIV) i reaktionstid hos unga vuxna och äldre. De 29 yngre och 30 äldre deltagarna i studien delades upp i två grupper, en träningsgrupp som gick igenom 15 sessioner av träning i exekutiv funktion och en kontrollgrupp som endast deltog vid pre- och posttestning. I träningsbatteriet tränades de exekutiva funktionerna uppdatering, skiftning och inhibering i enlighet med det teoretiska ramverk om exekutiv funktion som skapats av Miyake (2000). I studiens pre- och postmätningar användes reaktionstidsdata från tre tester: Serial Reaction Time (SRT), Flanker och Alternating Runs. Dessa tester skiljde sig från de som användes i träningsbatteriet.

Barns upplevelser av rörelse : -en intervjustudie med sex- och sjuåringar

In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.

Optimering av multiprocessorsystem med hjälp av schemaläggning

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

Framtagning av fäste för räcke

The mission from IKEA of Sweden was to make a further development of their existing trolley in the FRAKTA -serial. IKEA wants that the new product would make the opportunities better for people who don't have cars to carry their goods home easily on the bus, train or walk after their purchase.The report includes a suggestion for a new product that will fit into the existing FRAKTA -serial. The new development product will continue the same standard as the other products in the serial and it will also make it possible for customers to carry their goods home by public transportations..

Inverse Discrete Cosine Transform by Bit Parallel Implementation and Power Comparision

The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by 0.35 ìm technology. When implementing a design, there are several considerations like word length etc. were taken into account.

Skolsituationen för elever med betyget MVG i matematik : En fallstudie av fyra elever i grundskolans årskurs 9

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Seriemördare i fiktionen : Jeffrey Dahmer som karaktär hos Lotta Lotass och Joyce Carol Oates

Serial killers are present in most Media today: TV-shows, books, magazines, news shows and music. Research about them has been made in many fields, such as criminology, psychology and psychiatry. There is also research about the serial killer as a cultural being. In my paper I have looked into the serial killer in fiction. I have chosen to compare two novels that deal with the serial killer Jeffrey Dahmer.

Kommunikationseffektivitet och kommunikationsstrategier för L1- och L2-talare i referentiella problemlösningsuppgifter

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

Rätt person på rätt plats: Sambandet mellan personlighet, yrkesval och arbetstrivsel

This study investigated the relation between Extraversion and Conscientiousness with job satisfaction and job selection in the two occupational groups of telemarketing and administration. The study also set out to explore the relation between social desirability as assessed with an Implicit Association Test (IAT) and total reaction time on the IAT. The questionnaire was administered over the Internet to forty-one subjects (24 women and 17 men) in the age range 16-65. Results indicated that people working with telemarketing tend to be extrovert while people working with administration often are conscientious. Job satisfaction correlated with Extraversion in the telemarketing group.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
