  1. 1. The perception of actions and interactions : And the importance of context

    Författare :Joshua Juvrud; Gustaf Gredebäck; Denis Mareschal; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action understanding; action perception; motion; perception; context; environment; eye-tracking; pupil dilation; Psychology; Psykologi;

    Sammanfattning : The perception of actions and interactions is a dynamic process linked with perceptual processes, the internal and external states of the individual, prior experiences, and the immediate environment. Given these differential contexts, it is very likely there are differences in how infants perceive, interpret, and respond to actions. LÄS MER

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

    Författare :Martyna A. Galazka; Pär Nyström; Gustaf Gredebäck; Moritz Daum; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  4. 3. Neural processes underpinning pain perception : genetic, temporal, and behavioral factors

    Författare :Gránit Kastrati; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pain is an alarm system – warning us of dangers in the environment – yet becomes problematic when it transitions into chronic pain. It is defined, according to the International Association of Pain as “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage”.

  5. 4. Robot Manipulation Planning Among Obstacles: Grasping, Placing and Rearranging

    Författare :Joshua Alexander Haustein; Danica Kragic; Kostas E. Bekris; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; robot manipulation planning; sampling-based planning; fingertip grasp planning; placement planning; rearrangement planning; Computer Science; Datalogi;

    Sammanfattning : This thesis presents planning algorithms for three different robot manipulation tasks: fingertip grasping, object placing and rearranging. Herein, we place special attention on addressing these tasks in the presence of obstacles. LÄS MER

  7. 5. Flexible, Efficient, and Scalable Autonomous Exploration and Volumetric Mapping

    Författare :Daniel Duberg; Patric Jensfelt; Cesar Cadena; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exploration; Mapping; Autonomous Exploration; Volumetric Mapping;

    Sammanfattning : Autonomous mobile robots have in recent years started to enter households in the form of autonomous vacuum cleaners and lawn mowers. The applicability of more advanced and general purpose service robots is almost endless. That is, robots that can perform a variety of tasks, instead of being specialized for a single task. LÄS MER
