Експерименти Джорджа Стреттона з перевернутим зором

In 1896–1897, psychologist George M. Stratton wore a special optical device that altered the orientation of his visual field; it was an experimental apparatus, not a standardized invention commonly called an “invertoscope.” In the first trial he wore it for a total of 21.5 hours over three days; in a later trial, for about 87 hours over eight days. He described gradual adjustment in movement and at times a feeling that objects appeared upright again. This does not mean the brain literally flips an image: later studies found rapid motor adaptation but not a full subjective return of upright vision. Removing the apparatus temporarily disrupted familiar coordination; a universal claim that readapting afterward is faster does not follow unambiguously from Stratton’s single-subject experiment.
