Perception-Action Integration

Principle investigators: Edmund Wascher, Kristina Küper

Cooperation/Partners: Christian Beste (Dresden)

The transfer of visual information into an adequate action is essential for goal-directed behavior. Knowledge about the mechanisms of visuo-motor transfer is therefore essential for any action (and, in particular, for human-machine interactions).
The work in this project starts from selection of relevant information. Which features of a signal get amplified and which extenuated? How is information transfered into the process of action selection?
The integration of these questions into a physiolgically plausible model is the final aim of this research.

Goals

  • Validation of mechanisms of competitive information processing and extending this approach to other experimental settings
  • Integration of mechanisms of information uptake with storage and response selection accounts (in co-operation with the junior group “working memory”
  • Evaluating a neurophysiolgical model of perception action integration also by means of neurogenetics
