Letter: Not-so-invisible gorillas: another explanation

Published 8 January 2025

From Derek Bolton, Sydney, Australia

Ian Phillips considers distrust of one’s senses to be the most likely explanation for subjects denying having seen anything unusual in a video despite an unexpected object popping up, even if they could nevertheless convey some details of it. Alternatively, could it be to do with the phenomenon of blindsight? Visual processing involves many layers and brain regions. In blindsight, damage to one area can result in not being aware of any visual image yet still being able to guess the colours and locations of objects correctly (23 November 2024, p 12).
