Sidney Bradford, born 1907, was born blind but regained sight at age 52. He was the subject of many scientific studies of perception by neuropsychologistRichard Gregory.
Just after the restoration of his sight, Bradford was able to read (visually) the time on the ward clock. He could thus see by analogy with earlier touch experience.
Bradford did not perceive the ambiguity of the Necker cube and was unable to interpret the perspective of two dimensional art. Nevertheless, he could accurately judge the distance to objects in the same room (being familiar with these distances prevision by virtue of walking to them).
Sidney was born on July 19, 1843 in the town of Varick, on the shore of Cayuga Lake in the Finger Lakes Region of Upstate New York.
Sidney, without a musket, could have skipped the battle, but "he did not like to see the other boys going in, and he remain behind," so he followed the regiment into its position.
Sidney Burroughs was one of the many young men who nobly sacrificed a promising future for the welfare of his country, and must never be forgotten.
SidneyBradford, (May 30, 1906 - August 2, 1960), went blind at 10 months of age but regained sight after a cornea transplant at the age of 52.
For example, not having grown up with vision, Bradford did not perceive the ambiguity of the Necker cube.
In a similar analogy between vision and sightless (touch-only) experience, Bradford was able to visually read the time on the ward clock just after his operation.
