When two or more trusted cues are available to estimate the same property of the world, human perceptual systems usually exhibit data fusion, and it is possible to change the relative weights given to different cues through training (Ernst et al., 2000).
In situations where multiple trustworthy sources provide information about the same aspect of the world, human perception tends to synthesize this information, allowing individuals to refine their estimates based on experience. This refinement process enables people to adjust the relative importance assigned to different sources.
