The difference between objects and scenes... random thoughts [Of Two Minds]

I'm in the middle of my qualification exams and ran across this interesting paper:

Liu, Z Kersten, D Knill, DC Dissociating stimulus information from internal representation--a case study in object recognition. Vision research. 1999; 39(3): 603-12.

However, I'm very confused about them calling the figure on the left an object. This is a collection of objects in 3D space - making it a scene. I'm not sure that this nullifies their model - but this is not object recognition.

Vision is the process by which the brain converts the light stimuli into a mental world filled with abstract visual objects. If you stop to think about it, this is an incredible feat. There is nothing in the photons coming from two neighboring sections of an object that implies that they should…
How do we tell where an object is in a three-dimensional world when our eye only gives us two dimensions worth of information?

It shouldn't take you long to notice what's wrong with this picture: Obviously Nora is defying gravity in this shot -- you can't help but notice it. But in your first glance at the photo, how quickly do you notice what's wrong? Do you spot the oddity faster than you'd notice Nora in the original…
