There was a burst of something that was magic and also more, a shout louder than an earthquake and containing a thousand books, a thousand libraries, all spoken in a single cry that was Hermione; too vast to be understood, …

This is one of the saddest things I have ever read.

Also, it reminds me of Ed Fredkin's work on digital philosophy; specifically, conservation of information:

In ordinary physics, conservation of information is not something that has the same absolute character as conservation of momentum. If DP makes sense, then that would mean that in the real world information could never be lost, and as a consequence we might conclude that information would be conserved, absolutely, just as momentum is conserved.

I predict once Harry inevitably becomes omnipotent, he will recover Hermione's pattern, and reconstitute it in the center of a Hermione shell.

The study mentioned in your first link is most likely "Preferences and demands of the white rat for food", by Paul Thomas Young. This paper is includes a section tantalisingly named "Spatial factors in the feeding behavior of rats", which turns out not to be related to Feynman's story:

Eight rats showed marked individual differences in spatial behavior between the extremes of right and left dominance. The tendency of an animal to eat the test-food in a given position, right or left, frequently appears instead of preferential discrimination. Two attempts were made to control the factor of position.

1. The path of approach to the test-foods was moved bit by bit to the right or left.

2. The angular position of the pair of food-containers in relation to the line of approach was varied so as to advance one and withdraw the other.

Both methods gave the same result. It was possible to reduce, eliminate and even reverse the tendency of an animal to eat the food in a given right or left position. When the spatial advantage of both foods was the same, the conditions were most favorable for discovering the rat's food preferences. The animal could not, however, be forced into making a choice. Preference is assumed to depend upon organic factors rather than upon the environmental arrangement of test-foods.

Young's biographical note does not include a list of papers, but his Distinguished Scientific Contribution Award note does:

For his lifelong study of hedonic processes in behavior. Convinced of their significance for psychology, he endeavored to give objective reference and experimental validity to the concept. Although hedonic theorizing ran counter to the prevailing temper, he persisted in the belief that the control of behavior must be analyzed for affective value as well as intensity value. His research on preference showed the effect of experience in modifying acceptability; his work on need-free organisms clarified acceptance and appetitive behavior. Most recently, he has been examining composite stimuli and preference. Current renewed interest in hedonic theory rests in good measure on his experimental demonstrations and theoretical arguments."
