Aphantasia: the inability to form or use mental images as part of one's thinking or imagination
One can have aphantasia and still solve spatial reasoning problems
In which black-and-white panels do the two objects not match each other?
In the color panels, in which hand (left or right) is the stick figure holding the shape/color that matches the background?
(Answers below.)
Apparently people with aphantasia perform these tasks without manipulating visual images. In fact, they often do better than people who use visual image manipulation.
It’s not clear to me what it means to have aphantasia and still see and understand the images shown above.
Answers:
A: The figures in 3 and 4 don’t match.
