  1. 21. Keep it rolling : Straight-line orientation in South African ball-rolling dung beetles

    Author : Lana Khaldy; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ball-rolling dung beetle; Orientation; Heading direction network; Compass; Weighting; Celestial cues; Sun; Polarised light;

    Abstract : Representing a substantial range and variety in morphological and ecological niche, found on all continents of the globe (except for the Antarctic), the ball-rolling dung beetles provide an excellent model in which to study the heading direction network and the factors by which it is influenced. As soon as a ball-rolling dung beetle has located a fresh dung pile to feed on, it immediately starts shaping a piece of dung into a ball, rolling it away from the dung pat in as straight of a trajectory as the terrain allows.

  2. 22. Ocular aberrations and visual quality in aspherical and multifocal contact lenses

    Author : Anna Lindskoog Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Contact lenses;

    Abstract : Good visual quality and precise accommodation are required to be able to focus objects at distance and near, and are essential in order to be able to perform most tasks in life. Most eyes are not ideal eyes, i.e., they have different refractive errors which distort the produced image. READ MORE

    Abstract : Perception is a fundamental function because it allows organisms to be in contact with the environment and adjust to environmental conditions. Humans also possess higher intellectual functions, which allow for elaborate handling of perceptually obtained information. READ MORE

  4. 24. Social causality in motion : Visual bias and categorization of social interactions during the observation of chasing in infancy

    Author : Martyna A. Galazka; Pär Nyström; Gustaf Gredebäck; Moritz Daum; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social causality; motion; animacy perception; chasing goal-directed motion; heat-seeking; EEG; P400; Nc; spatial proximity; non-contact causality; functional specialization; specialized perception; evolution; Psychology; Psykologi;

    Abstract : Since the seminal work of Fritz Heider and Marienne Simmel (1944) the study of animacy perception, or the perception and attribution of life from the motion of simple geometrical shapes has intrigued researchers. The intrigue for psychologists and vision scientists then and today centered on the stark disconnect between the simplicity of the visual input and the universal richness of the resulting percept.
