    Keywords : preschool vision screening; referral criteria; children; vision; preterm; cerebral visual impairment; visual perception; ocular fundus morphology;

    Abstract : Aims: Papers I & II: To evaluate the consequences of changes in the criteria for referral to an eye clinic following general pre-school vision screening. According to the former criteria all 4 year old children in the Göteborg area, with visual acuity (VA) ... READ MORE

  4. 17. Reaching for Excellence? : Does training improve motor abilities and cause cascading effects in the visual attention and social perception domain?

    Author : Linda van den Berg; Gustaf Gredebäck; Pär Nyström; Erik Domellöf; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early Motor Training; Sticky Mittens; Infants; Motor Development; Reaching; Grasping; Social Perception; Visual Attention; Psychology; Psykologi;

    Abstract : claimed in the last 20 years. Being able to reach for objects provides infants with an interactive interface with their environment. After reach onset, objects can be explored closer to the face and manipulated. Social perception abilities and visual attention have both been found to relate to motor development. READ MORE

  5. 18. Mind in Action : Action Representation and the Perception of Biological Motion

    Abstract : The ability to understand and communicate about the actions of others is a fundamental aspect of our daily activity. How can we talk about what others are doing? What qualities do different actions have such that they cause us to see them as being different or similar? What is the connection between what we see and the development of concepts and words or expressions for the things that we see? To what extent can two different people see and talk about the same things? Is there a common basis for our perception, and is there then a common basis for the concepts we form and the way in which the concepts become lexicalized in language? The broad purpose of this thesis is to relate aspects of perception, categorization and language to action recognition and conceptualization. READ MORE

  6. 19. Bio-inspired retinal optic flow perception in robotic navigation

    Author : Björnborg Nguyen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robotic navigation; active fixation; visual perception; bionics; Retinal optic flow fields; gazing; optic flow; retinal flow path;

    Abstract : This thesis concerns the bio-inspired visual perception of motion with emphasis on locomotion targeting robotic systems. By continuously registering moving visual features in the human retina, a sensation of a visual flow cue is created. An interpretation of visual flow cues forms a low-level motion perception more known as retinal optic flow. READ MORE

  7. 20. 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
