Temporal audiovisual coherence strength determines visual weighting in fusion.

Evidence

Audiovisual fusion has long been considered as an automatic fusion process (e.g. Massaro 1987 ). However Exp. A. confirms that the contextual stimulus may modulate fusion as in our previous experiments (Nahorna et al. 2012 ; Ganesh et al. 2013 ; Nahorna et al. 2015 ) and extends the concept to the case of competing sources. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5177 (#corroborates, via linked claim)
