1. 6. Cognitive training in young and old adults : Transfer, long-term effects, and predictors of gain

   Författare :Petra Sandberg; Anna Stigsdotter Neeyl; Michael Rönnlund; Boo Johansson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive training; aging; old adults; executive function; life-span; individual differences; episodic memory; inhibition; shifting; updating; cognitive control; strategy training; mnemonics; predictors; Psychology; psykologi;

   Sammanfattning : Aging, also in the absence of pathological conditions, is associated with cognitivedecline, especially in so called fluid abilities, such as episodic memory andexecutive functions. Due to an ongoing demographic shift, a larger part of thepopulation will reach higher ages, and more people will be affected by age-relatedcognitive decline. LÄS MER

3. 7. The aging brain and changes in cognitive performance : Findings from morphometry and quantitative susceptibility mapping of iron

   Författare :Ninni Persson; Håkan Fischser; Kristine B. Walhovd; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brain aging; volumes; ndividual differences; QSM; cognitive aging; iron; episodic memory; fluid-; crystalized abilities; sex differences; gender differences; Psychology; psykologi;

   Sammanfattning : Brain aging is a heterogeneous phenomenon, and this thesis illustrates how the course of aging can vary within individuals over time and between individuals as a function of age, sex, and genetic variability. We used two contrasts from magnetic resonance imaging (MRI), namely spin-lattice T1-weighted imaging, and quantitative susceptibility mapping (QSM) from gradient-echo images, to picture the aging brain, by means of morphometric measures and brain-iron concentrations.

4. 8. Essays on Cognitive Development and Medical Care

   Författare :Mattias Öhman; Matz Dahlberg; Erik Grönqvist; Louise von Essen; Martin Karlsson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fluoride; Cognitive ability; Non-cognitive ability; Income; Education; Employment; Dental health; Mortality; Information; Health; Screening; Abdominal aortic aneurysm; Myocardial infarction; Antidepressants; SSRI; Propensity score matching; Economics; Nationalekonomi;

   Sammanfattning : This thesis consists of four self-contained papers.Essay I (with Linuz Aggeborn): Fluoridation of the drinking water is a public policy whose aim is to improve dental health. Although the evidence is clear that fluoride is good for dental health, concerns have been raised regarding potential negative effects on cognitive development. LÄS MER

5. 9. An investigation of cognitive aspects affecting human performance in manual assembly

   Författare :Anna Brolin; Keith Case; Peter Thorvald; Leo De Vin; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive ergonomics; Manual assembly; Manufacturing; Usability; Cognitive workload; Information presentation; Material presentation; Product variants; Kitting; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

   Sammanfattning : Modern manufacturing systems seem to be shifting from mass production to mass customisation, which means that systems must be able to manage changes in customer demands and requirements, new technology as well as environmental demands. This in turn leads to an increase in product variants that need to be assembled. LÄS MER

7. 10. Intelligence and models for cognitive development

   Författare :Linda Wänström; Daniel Thorburn; Gösta Hägglund; Dag Sörbom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intelligence; cognitive development; sample size; multilevel models; latent growth curve models; Statistics; Statistik; statistik; Statistics;

   Sammanfattning : This dissertation focuses on cognitive development. In papers I and II, I study a special model, the second order latent growth curve model, that can be used to study cognitive development. Algebraic expressions for the variance of the estimation of slope differences are given. LÄS MER
