Is there terminology for perceptual illusions at the moment that figure-ground reversal occurs? I'm looking for a term in the perception / cognition area of research.  

I recently saw this visual illusion that 'flips' what is negative-space and what is positive-space.  This is known in the arts as "figure-ground reversal"

I am looking for a word / term that addresses when the thing we are observing changes, such that the parts that signify the 'figure' and 'ground' are themselves switched.  Is there a word for this?  Does Ecological Psychology have a way that it organizes such stimuli?



I would think there may be a term that address when our perception 'flips' the perception of a static image, and afterward we are biased to perceive the 'ground' differently.  This happens when we see a vase instead of faces.  

But I don't know that word, nor do I know if it applies to the occurrence of when a thing/image/perceptual-field changes, in order to action the figure-ground reversal.
There are many such illusions. It mostly belongs to pattern-recognition and gestalt psychology. From German it means "shape", "form", "essence". To answer your question, I think, here there are illusory contours (when you watch and understand an illusion) and lateral inhibition (when you have got new understanding of the picture and compare it with previous form).

Enjoy more pictures ;)
