Art and Religion VI: "Imagination can change what we see and hear"

Having just wrote on Tanya Luhrmann and the role of the imagination in religion, I just noticed that Science Daily came out with an article on how the "imagination"can influence what we hear and what we see. Now, just by reading this, it is vague in what sense they are using the term imagination. And how they actually got participants to "imagine" something from creating an illusion.

"In the first experiment, participants experienced the illusion that two passing objects collided rather than passed by one-another when they imagined a sound at the moment the two objects met. In a second experiment, the participants' spatial perception of a sound was biased towards a location where they imagined seeing the brief appearance of a white circle. In the third experiment, the participants' perception of what a person was saying was changed by their imagination of a particular sound."

Without reading the actual paper, I would be interested in how they actually measured and induced the "imagination". But I don't think the claim is new but rather reinforces that our imagination can influence our perceptions of reality. Imaginary friends, Schizophrenics, Hallucinations, hearing the wrong thing, phantom sounds, etc. etc. all of these things can affect our experience of reality.
