In the vision literature, there are many studies examining strategies that observers use to combine information provided by each of multiple cues in a visual environment. It has been shown that the weights applied to different cues are adjusted by the observers according to their reliability: cues that are informative for a task and stable cues that are less often manipulated by the experimenter, receive higher weights than less informative, and less stable cues that are manipulated more often (Jacobs 2002; Triesch et al. 2002). For example, Jacobs and Fine (1999) investigated the relative contribution of motion and texture cues to the perceived depth of a simulated object. After some training, in which one cue was informative and the other was irrelevant, observers’ weights for the relevant cue were larger than for the irrelevant one.
