Multisensory responses reach higher levels earlier. Left: this analysis determined if and when responses quantified as qsums (top) or event estimates (bottom) reached threshold criteria levels. Middle and Right: multisensory responses crossed criteria levels more often (Middle) and earlier (Right) than did unisensory responses, and there were virtually no cases (see asterisk and arrow) where unisensory responses reached a criterion not also reached by the multisensory response.
