The Positions of Retinal Images

Abstract

THE thanks of your psychological readers are due to Mrs. Ladd Franklin for having, in her letter published in your number of February 13, called attention to Schön's experiments, which, as she says, have been unaccountably overlooked. I have in consequence been repeating the experiment which Mrs. Franklin describes, but so far with purely negative results. Although some of the observers gave answers which might hastily have been interpreted as confirmations of Schön's illusion, a further analysis showed conclusively that no one on whom I have experimented, so far, perceived it.
