The process by which separatesensory cues to (typically) the same event in the external environment arecombined (integrated) into a single multisensory percept. Recent models of this process have argued thatmature adults achieve this in an optimal way via maximum likelihood estimation that is they weight each cue in the combined estimate in accordance with itsreliability (Ernst & Banks, 2002).
