Abstract:
This talk is about two largely unrelated studies in the area of perception. In the first part, results from an experiment on human adaptation to visual feedback delays will be presented. Humans recalibrate their perceived simultaneity to compensate for additional latencies and the amount of perceptual recalibration correlates to the magnitude of behavioural effects. This study is the first to show strong adaptation, as it is known to result from spatial perturbations (e.g., prism goggles), in the temporal domain. The second part presents results from an evolutionary robotics model of multisensory size discrimination. This exploratory study raises a number of issues about the kind of experimental procedure used in behavioural research on multimodal integration. Simulation models of this kind are suitable tools to sanity-check your implicit prior assumptions underlying experimental research.
