It is well established that if multiple cues provide information about the same quantity, from these combined by weighting each cue inverse of its variance. This implies weights are determined variances only. However, this view challenged studies showed feedback actual value can induce changes in when consistent with one but not other. We developed a paradigm allowed us to measure time course reweighting. Subjects placed an object flush onto slanted surface. Monocular and binocular provided slant could be inconsistent another. received haptic whether they had oriented correctly contacted was either monocular or information. found weight given visual increased relatively fast, leading mean change 0.18 after 52 conflict trials. Thus, unless somehow influences reliability individual cues, fully also depend on accuracy cue.
