    Sammanfattning : This work consists of five articles about the statistical aspects of financial time series models. The first three papers investigate and develop the inverse normal Gaussian stochastic volatility (NIGSV) model, initially suggested by Barndorff- Nielsen (1997). LÄS MER

  3. 12. If only I could sleep, maybe I could remember

    Författare :Frida H Rångtell; Christian Benedict; Ti­ina Paunio; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sleep; Memory; Learning; Motor skills; Praise; Reward; Sleep deprivation; Sex-differences; LED-screens; Circadian rhythm; Competence-based self-esteem;

    Sammanfattning : Memory lies the ground for human cognitive skills, enabling complex social interaction, abstract thinking, and execution of precise motor skills. Development of these memory functions can be modified by several factors, including previous knowledge, reward, and sleep. LÄS MER

  4. 13. The influence of social relationships and leisure activity on adult cognitive functioning and risk of dementia : Longitudinal population-based studies

    Författare :Daniel Eriksson Sörman; Michael Rönnlund; Anna Sundström; Lars-Göran Nilsson; Martin Lövdén; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive functioning; cognition; memory; dementia; Alzheimer’s disease; cognitive reserve; reverse causality; old age; middle age; leisure activity; social relationships; social network; longitudinal; Psychology; psykologi;

    Sammanfattning : Today, as we live longer, dementia diseases are becoming more prevalent around the world. Thus, further knowledge of how to maintain levels of cognitive functioning in old age and how to identify factors that postpone the onset of dementia are of acute interest. Lifestyle patterns and social life are important aspects to consider in this regard. LÄS MER

  5. 14. Determinant Factors for Memory Performance in Human Aging: A Study of Environmental, Person-Based, and Non-Cognitive Predictors Contributing to Memory Performance in old Adults

    Sammanfattning : The aim of this thesis was to examine the importance of environmental, non-cognitive, and person-based variables for memory performance in old adults. Study I was conducted in cooperation with the Gerontology Research Centre and the Department of Psychology in Lund. LÄS MER

  7. 15. An Associative Memory Trace in the Cerebellar Cortex

    Författare :Dan-Anders Jirenhed; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; neuropsychology; Classical Conditioning; Cerebellum; Purkinje cell; Physiology; Fysiologi; Neurology;

    Sammanfattning : Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response.
