  2. 1. Peripheral Vision : Adaptive Optics and Psychophysics

    Author : Robert Rosén; Peter Unsbo; Larry Thibos; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. READ MORE

  4. 2. Tactile Perception - Role of Physical Properties

    Author : Lisa Skedung; Mark Rutland; Katrin Danerlöv; Sören Andersson; Ann Maria Cornell; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; Chemistry; Kemi;

    Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE

  6. 4. The psychophysics of human echolocation

    Author : Carlos Tirado Aldana; Mats Nilsson; Daniel Västfjäll; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Detection; Individual differences; Human echolocation; Lateralization; Localization; Echobot; Psychology; psykologi;

    Abstract : Echolocation is the capacity to detect, localize, discriminate, and, overall, gather spatial information from sound reflections. Since we began studying it in humans, we have learned several things. First, most humans can echolocate to some degree. READ MORE

  7. 5. Sick of smells : Empirical findings and a theoretical framework for chemical intolerance

    Author : Linus Andersson; Steven Nordin; Monique Smeets; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Chemical Intolerance; Unexplained Medical Symptoms; Environmental Intolerance; Event-related potentials; functional magnetic resonance imaging; psychophysics; sensitization; habituation; Psychology; psykologi;

    Abstract : Chemical intolerance (CI) is a term that refers to the surprisingly common phenomenon of persons getting ill from everyday chemicals. Although seemingly similar to asthma and allergies, CI sufferers do not react to exposures with increased histamine release. READ MORE
