Visual anomolies as a precursor to acquired aphantasia
1 min readByBenson Kaukonen
i have late onset of aphantasia; i noticed that i was unable to make visual memories maybe ten years ago, when i was in my late 60s ..... an editorial aside is that none of the eye doctors, general practitioners, or neurologists i consulted keyed in on my repeating that i "can not make visual memories ....." my snarkiness aside, i've wondered what might have been a causative factor, and here's what i'm wondering:
my left and right eyes do not "yoke," meaning that i have double vision; were i to watch a ballet solo i'd see a pas de deux; sometimes the two images merge but mostly not, and what i'm thinking is that visual signals, arriving at minutely different times in the visual cortex, cannot be processed as a coherent image and cancel one another out ......
cancellation of signals arriving at different times is an audio phenomenon in recording or live musical situations; called phase shifting it occurs when the signals from two microphones, placed at different distances from a sound source, have their signals summed and ...... all the high frequencies disappear!
i'm curious as to how people might account for late onset or how they account for their experience as an aphatasic in general ......
lemme know!
