The 20th International Multisensory Research Forum (IMRF) brings together experts in multisensory research from Europe and overseas in Ulm, Germany. We will present work on “Parsing response times in multisensory decisions: the effect of signal strength and effector organ” on Tuesday afternoon (Session “Time, Space and Motion”, 3:15-4:45pm).
Looming motion is an ecologically salient signal that often signifies danger. In both audition and vision, humans show behavioral biases in response to perceiving looming motion, which is suggested to indicate an adaptation for survival. However, it is an open question whether such biases occur also in the combined processing of multisensory signals. Towards this … Read more
The availability of signals from multiple senses is often beneficial for perceptual decisions. To study such benefits, models of multisensory decision-making are typically fed with the behavioural performance as measured separately with unisensory component signals. Critically, by doing so, the approach implicitly makes the so-called context invariance assumption, which states that processing of a signal … Read more
Responses to two redundant sensory signals are typically faster than responses to the individual component signals. This redundant signals effect (RSE) is extensively studied not only with an impressive variety of signals but also across different subject populations focusing on development, aging, and many clinical samples. Yet, a standardized methodology to analyse and interpret the … Read more
The European Conference for Cognitive Science (EuroCogSci) will feature contributed papers, symposia, and posters covering all subfields of cognitive science, and will bring together a large number of experts from Europe and overseas in Bochum, Germany. We will present new work on logic decision gates in multisensory processing on the first day of the conference … Read more
The 42nd edition of the European Conference on Visual Perception (ECVP) will be held in Leuven, Belgium from August 25th – 29th, 2019. We will present new modelling work on multisensory reaction times on the final day of the conference in the session on information processing (5-6 pm, location AV03.12).
Multisensory signals allow faster responses than the unisensory components. While this redundant signals effect (RSE) has been studied widely with diverse signals, no modelling approach explored the RSE systematically across studies. For a comparative analysis, here, we propose three steps: The first quantifies the RSE compared to a simple, parameter-free race model. The second quantifies … Read more
