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.

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.

Rotundus AB är ett världsledande företag inom området för sfäriska robotar som håller på att utveckla den markbundna farkosten GroundBot(tm). För att detektera robotens translations- och rotationsrörelser används accelerometrar och hastighetsgyron. Dessutom används sensorerna för tröghetsnavigering när GPS-täckning saknas.Målet med projektet innebär att ta fram en metod för att utvärdera precisionen hos sensorer för robotens tröghetsnavigeringsenhet. Metoden koncentrerar sig på fyra av sensorernas felkällor: Skalfaktor, bias, slumpvandring och biasinstabilitet.För att beräkna skalfaktorn och biasen används linjära minsta kvadratmetoden där utsignalen från sensorn anpassas mot ett teoretiskt värde. Slumpvandringen och biasinstabiliteten utvärderas med Allans varians..

Att ha attityder grundade i rationella tankar uppfattas som mer önskvärdän att ha attityder som är grundade i externa faktorer. Människor ärbenägna att uppfatta individer som håller med dem som mer rationellaoch mindre externt influerade i sina preferenser än individer som intehåller med. Construal Level Theory förutsätter högre psykologiskdistans för med sig ökad bias. Högstatusindivider har en högrepsykologisk distans vilket leder till ökad bias. I studien undersöks hurpsykologisk distans och individens benägenhet att tolka världen naivt,utifrån eget perspektiv, inverkar på mellangruppsattributioner.Resultaten visar att deltagarna skattar preferenserna av de som harsamma åsikt i en fråga som mer rationella än dem som har motsatt åsikt,och att maktposition leder till ökad bias.

Bemanningsbranschen i Sverige växer snabbt och närmare en procent av den totala arbetskraften i landet är anställd i bemanningsföretag. Tidigare forskning har ur ett organisationspsykologiskt perspektiv undersökt hur direktanställd personal reagerar på inhyrd personal och vice versa, då indikationer på att stigmatisering av inhyrd personal negativt påverkar arbetstillfredsställelsen framkommit. Dock har inga socialpsykologiska studier om direktanställdas arbetstrivsel i telemarketingbranschen kunnat hittas. Utifrån denna bakgrund syftar denna studie till att undersöka ingroup/outgroup bias i relation till direktanställd personals arbetstrivsel inom telemarketingbranschen. I en enkät ombads direktanställda vid ett telemarketingföretag att ta ställning till påståenden om personalrelationerna på arbetsplatsen.

Syftet med föreliggande studie var att försöka reda i litteraturen kring två välkända begrepp inom Affective Forecasting nämligen Impact Bias, som innebär att människor har en tendens att överskatta i vilken utsträckning de kommer att uppleva en viss känsla i en framtida situation än vad som senare visar sig vara fallet, och Empathy Gaps, som innebär att människor har en tendens att underskatta i vilken grad känslotillstånd kommer att påverka deras preferenser i en framtida situation samt pröva dessa begrepp i en och samma enkätundersökning. Etthundra sextiotvå studenter, slumpvist uppdelade i två grupper, Känslogrupp och Preferensgrupp, deltog frivilligt i undersökningen. Enkätundersökningen var en mixad design med grupp (känsla kontra preferens) som mellangruppsfaktor och förtest kontra eftertest som inomgruppsfaktor. I studien visade samtliga gruppers resultat i linje med Impact Bias teorin, dvs. att deltagarna i både Känslogrupp och Preferensgrupp skattade lägre i eftertest (actual) än pretest (forecasting).

The content of teaching materials considerably affects pupils? attitudes and worldview. This paper is an analysis of textbooks used in 7th through 9th grade of the Swedish School system in Swedish as a Second Language (SSL) and English as a Foreign Language (EFL). The purpose of this paper is to look at which minority groups, the five official national minorities as well as other minorities, are included and portrayed in the textbook series Tre gånger svenska and Wings Mini as well as to see if there is any bias in their portrayal. The seven types of bias investigated; invisibility, stereotyping and generalizations, unreality, imbalance and selectivity, fragmentation and isolation, linguistic bias and cosmetic bias are an adaption of the framework to detect bias in curriculum materials presented by Sadker and Zittleman (2002/2003).

Earlier models that measured de facto harmonization of international accounting mainly used indices and other related statistical models. Those approaches do not account for the relative importance of individual balance sheet items or expense items being harmonized. This paper therefore proposes a different approach using Runsten?s (1998) permanent measurement bias model. That way it is possible to quantify the harmonization process by accounting for differences among companies.

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 high debt levels experienced in European Countries have lead to academic interest in the deficit bias -the tendency for governments to run budget deficits and accumulate debt. In part one of this thesis a surveyof the economic literature on the origins and solutions to the deficit bias are conducted. The proposedinstitutional solution to the deficit bias in the form of Fiscal Policy Councils (FPC) are outlined and existingEuropean FPCs presented. Based on the works of Calmfors and Wren-Lewis (2011) the EuropeanCommission (EC) is defined as an FPC. Based on this survey, two hypothesis are formulated: (1) theforecasts of future macro-economic events and fiscal performance will differ between the national FPCs andthe national government.

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..
