I'm afraid they're too old. I wasn't able to track them with Google Scholar / WOS.

<p>If one is experiencing elaborated visual hallucinations, what will happen when one puts on reversing goggles? Will hallucinations change their orientations as well? Links to relevant papers will be most welcome.</p>

Interesting question...The idea of global precedence may be useful here. This question particularly reminds me of this idea in the context of [face inversion identification tasks](http://en.wikipedia.org/wiki/Global_precedence#Face_inversion).
