This experiment has been reproduced in one way or another. Most significantly by Jan Degenaar, who spent many hours wearing "left to right inverting goggles", in his excellent and readable thesis "Perceptual engagement, a sensorimotor approach to phenomenal experience". To my mind, the most important observation is that the scene did not "fully" invert "back to normal", but it was only visuals which Degenaar had appropriately re-learned which appeared "normal". For example, on the first day, walking down a street would make him see a car drive down the road to one side of him, but he'd hear it on the other side of him. Later on, the vision and the sound appeared on the same side, but if he looked at the number plate it was still "backwards". He had learned to locate sound while wearing inverting goggles, so the experience was "normal", but not learned to read while wearing inverting goggles, so that experience was still "strange". Other papers, such as "The myth of upright vision" show that the change happens faster than can be attributed to "neural plasticity". https://scholar.google.com/scholar?cluster=1962488607431732206&hl=en&as_sdt=0,5 https://scholar.google.com/scholar?cluster=19624886074317322...
