It would be interesting to know if blind or blind-folded dogs also exhibit this behaviour.

My intuition is that head-tilting behaviour is more analogous to how we (humans) look up and the to left/right when concentrating. That feels less like augmenting the visual data and more like blocking visual input while we focus compute on recall and more complex thought.

My dog is blind and does the head tilt when she hears certain noises (e.g. dogs barking). She was not born blind though, in case that could make a difference.

It’s interesting some poker players before making a ridiculous bluff will look up and to the right.

It's a common tell for lying in general, not just bluffing in poker.
