Researcher Kohske Takahashi presents a new sort of optical illusion that he has named “curvature blindness” which is manifested as the identical sets of lines pass over the grey field and appear to retain and take on alternating properties of a wave and a more angular trough. No one is certain about the mechanism behind this cognitive illusion but Takahashi suspects that registering sharper corners might be the default, Gestalt mode of human visual perception and what we retreat to when faced with a confusing arrangement. Same-otherwise, this visual trickery and related stunts could also be grounded in the self-deception that the human brain creates for our benefit that reduces the granularity of the senses and make things seem smooth and continuous, despite gaps and delays.
