Cognitive Daily has a nice post on an experiment designed to probe how we combine information from different senses: in this case, touch and vision.

Experimenters gave subjects visual (little sparks on a video screen) and touch (taps on the hand) cues, and had them count how many.

It turns out that when people got both types together, they interpreted them differently than when they got only one or the other—they responded to the sameness and difference (analogy) between the cues to construct their reality.
