  2. 1. The Role of Odor and Sensory Irritation in Human Chemical Sensitivity

    Author : Li Zheng; Birgitta Berglund; Staffan Hygge; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Odor and irritation detection; recognition; threshold; choice theory; intensity; chemical sensitivity; threshold; and sensitivity index.; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The main objective of this thesis is to apply complimentary psychophysical theories and methods to investigate human perception of odor and sensory irritation of chemical compounds present in indoor air. Three psychophysical theories: Signal Detection Theory (SDT), Threshold Theory and Luce’s Choice Theory (CT) were applied to measure detection and recognition of odor and sensory irritation of two odorous irritants (pyridine and formaldehyde) by using the method of constant stimuli.

  4. 2. Physiological properties of unmyelinated low-threshold tactile (CT) afferents in the human hairy skin

    Author : Katarina Wiklund Fernström; Göteborgs universitet; []
    Keywords : Human; microneurography; mechanoafferent; unmyelinated; sensory; touch; temperature; capsaicin;

    Abstract : For more than a decade it has been known that human skin is supplied with a system of slowly conducting unmyelinated afferents that respond strongly to innocuous skin deformation (Nordin, 1990; Vallbo et al., 1993). READ MORE

  5. 3. Foot lesions in diabetic patients aged 15-20 years : a population-based study

    Author : Bengt Borssén; Folke Lithner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus; Foot deformities; Sensory threshold; M. extensor digitorum brevis;

    Abstract : Foot problems are not only the most common but in general also the most severe of the diabetic complications. The age group 15-50 yrs in this study was chosen because these patients were considered to be at their most active age and were felt to require optimal foot function. READ MORE

  6. 4. Physical loads and aspects of physical performance in middle-aged men and women

    Author : Margareta Torgén; Uppsala universitet; []
    Keywords : Medical sciences; physical work load; age; gender; muscle strength; aerobic power; sensory threshold; epidemiology; questionnaire; reproducibility; validity; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Abstract : This investigation aimed at a description of different aspects of physical loads during a 24 year follow-up (1970-1993) in 484 men and women born between 1935 and 1952, in relation to different aspects of physical performance, as measured at follow-up. The subjects were originally recruited in 1969 from the Stockholm county generalpopulation. READ MORE

  7. 5. Auditory and Olfactory Abilities in Blind and Sighted Individuals : More Similarities than Differences

    Author : Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; Psychology; psykologi;

    Abstract : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.
