Research Groups: Visual Attention and Perception Representation of Space and Time in Cognitive Processes

Differences in visual and haptic grasping space and near scale space perception Annekatrin Klopp Issue: The perception of space, especially of the grasping space and the near distant action space, is multimodal. The single perceptual systems provide information about space that converge and partly overlap with information of the other modalities. The resulting redundancy of information is an important characteristic of perception. It is said that the absence of one sensory system (for instance in blindness) destroys the informational structure that is normaly available (Millar 1994). Experiments with conflicting visual and haptic information demonstrate a more or less strong dominance of vision. The question here is how the information of the different modalities is coming to terms or converges. There are two theoretical standpoints in this question. Are there two different modality specific modes of representation that converge and form up a new mode of representation or is there a basic mode of representation into which the information of the other modality has to be integrated.

In GrKK since 10/97 as Ph.D. student

Goal: Are there different modes of representations in the different modalities for the same space compartments?. Do the modes of representation differ in different space tasks (for instance in form perception)? Are there different intra-modal representations which are responsible for the differing performances in visual and haptic space tasks? These are some questions I hope to answer .
