  2. 6. Unwanted wanted sounds : Perception of sounds from water structures in urban soundscapes

    Author : Maria Rådsten Ekman; Mats E Nilsson; Catherine Lavandier; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perception; psychoacoustics; soundscape; water-sound; psykologi; Psychology;

    Abstract : Water structures, for example, fountains, are common design elements in urban open public spaces. Their popularity is probably explained by their visual attractiveness. Less is known about how the sounds of water struc-tures influence the urban soundscape. READ MORE

  4. 7. Binding Three Kinds of Vision

    Author : Leo Poom; Myron Braunstein; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Attribute-invariance; binding; contours; edge linking; gestalt-laws; illusory contour; lateral interactions; neuronal mechanisms; tilt effect; vision; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Pictorial cues, together with motion and stereoscopic depth fields, can be used for perception and constitute ‘three kinds’ of vision. Edges in images are important features and can be created in either of these attributes. READ MORE

  5. 8. Breast Tomosynthesis: Aspects on detection and perception of simulated lesions

    Author : Pontus Timberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. READ MORE

  6. 9. Bird Vision: Spatial acuity and colour discrimination in bright and dim light

    Author : Olle Lind; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal vision; Visual ecology; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    Abstract : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. READ MORE

  7. 10. Colour Vision in Birds : Comparing behavioural thresholds and model predictions

    Author : Peter Olsson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gallus gallus; receptor noise; visual modelling; animal training; colour discrimination; colour constancy;

    Abstract : Birds use colour vision for many biologically relevant behaviours such as foraging and mate choice. Bird colour vision is mediated by four types of single cones, giving them an extra dimension of colour information compared to trichromatic humans. READ MORE
