The duration of uncertain times: audiovisual information about intervals is integrated in a statistically optimal fashion.

Often multisensory information is integrated in a statistically optimal fashion where each sensory source is weighted according to its precision. This integration scheme isstatistically optimal because it theoretically results in unbiased perceptual estimates with the highest precisionpossible.There...
