The BPS Research Digest reports on a new study that shows that 90 minutes of being blindfolded significantly improves our ability to locate sounds.
Next the participants spent 90 minutes sitting quietly with the blindfold on. Crucially, when they repeated the [sound location] task after this, their accuracy was improved as they no longer underestimated the location of the sounds as much… In fact their performance had become more typical of a blind person performing this kind of task.
There’s more on the study over at the BPSRD including a link to the original paper.
