A multisensory approach to temporal binding construes actions and effects as individual sensory signals, which are each perceived with a specific temporal precision. When they are integrated into one multimodal event, like an action-effect chain, the extent to which they affect this event's perception depends on their relative reliability. We test whether this assumption holds true in a temporal binding task by manipulating certainty of actions and effects. Two experiments suggest that a relatively uncertain sensory signal in such action-effect sequences is shifted more towards its counterpart than a relatively certain one. This was especially pronounced for temporal binding of the action towards its effect but could also be shown for effect binding. Other conceptual approaches to temporal binding cannot easily explain these results, and the study therefore adds to the growing body of evidence endorsing a multisensory approach to temporal binding.}, language = {en} } @article{PfisterKlaffehnKalckertetal.2021, author = {Pfister, Robert and Klaffehn, Annika L. and Kalckert, Andreas and Kunde, Winfried and Dignath, David}, title = {How to lose a hand: Sensory updating drives disembodiment}, series = {Psychonomic Bulletin \& Review}, volume = {28}, journal = {Psychonomic Bulletin \& Review}, issn = {1069-9384}, doi = {10.3758/s13423-020-01854-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235195}, pages = {827-833}, year = {2021}, abstract = {Body representations are readily expanded based on sensorimotor experience. A dynamic view of body representations, however, holds that these representations cannot only be expanded but that they can also be narrowed down by disembodying elements of the body representation that are no longer warranted. Here we induced illusory ownership in terms of a moving rubber hand illusion and studied the maintenance of this illusion across different conditions. We observed ownership experience to decrease gradually unless participants continued to receive confirmatory multisensory input. Moreover, a single instance of multisensory mismatch - a hammer striking the rubber hand but not the real hand - triggered substantial and immediate disembodiment. Together, these findings support and extend previous theoretical efforts to model body representations through basic mechanisms of multisensory integration. They further support an updating model suggesting that embodied entities fade from the body representation if they are not refreshed continuously.}, language = {en} }
