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

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
