  1. 1. Subjective Cognitive Complaints in the Working Population : The Influence of Objective Cognitive Functioning and Working Conditions

    Författare :Cecilia U. D. Stenfors; Lars-Göran Nilsson; Töres Theorell; Linda L. Magnusson Hanson; Gabriel Oxenstierna; Nancy Pedersen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Subjective cognitive complaints; cognitive functioning; declarative memory; episodic memory; semantic memory; working memory; executive cognitive functioning; psychosocial working conditions; demand-control-support model; population-based; Psychology; psykologi;

    Sammanfattning : Cognitive functioning is important for managing work and life in general. However, subjective cognitive complaints (SCC), involving self-perceived difficulties with concentration, memory, decision making, and clear thinking are common in the general and in the working population and can be coupled with both lowered well-being and work ability.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cognitive tests; neuropsychology; Alzheimer’s disease; dementia with Lewy bodies; mild cognitive impairment; treatment evaluation; acetylcholinesterase inhibitors; differential diagnosis; longitudinal studies; dementia; cerebrospinal fluid; forecasting;

    Sammanfattning : Background It is estimated that 34 million people suffer from dementia, costing society US$422 billion each year. Alzheimer’s disease (AD) is the most common dementia and the global prevalence is predicted to increase to over 100 million people by the year 2050, with the greatest increase in developing countries.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cognitive Control; fNIRS; mental fatigue; exhaustion disorder; TBI; children; mathematical cognition; proactive cognitive control;

    Sammanfattning : This thesis aimed to investigate the ability to adjust cognitive processes and behavior, i.e., cognitive control, and its related functional activity in the cortex. LÄS MER

  4. 4. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

    Författare :Sushmit Mishra; Mary Rudner; Stefan Stenfelt; Jerker Rönnberg; Thomas Lunner; Mithell S. Sommers; Linköpings universitet; []
    Nyckelord :Working memory; cognitive spare capacity; updating; inhibition; Arbetsminne; kognitiv reservkapacitet; uppdatering; inhibition;

    Sammanfattning : Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

  5. 5. Cognitive Sensing and Transmission Strategies

    Författare :Kasra Haghighi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hidden Markov Model; Spectrum Sensing; Sequential Spectrum Sensing; Cognitive Radio; Spectrum Utilization;

    Sammanfattning : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. LÄS MER
