Aphantasia (/ ˌeɪfænˈteɪʒə / AY-fan-TAY-zhə, / ˌæfænˈteɪʒə / AF-an-TAY-zhə) is the inability to visualize. [1] The phenomenon was first described by Francis Galton in 1880, [2] but has remained relatively unstudied. Interest in the phenomenon renewed after the publication of a study in 2015 conducted by a team led by Adam Zeman ...

It is not due to a deficit in vision (acuity, visual field, and scanning), language, memory, or intellect. [1] While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as ...

Classic examples of this phenomenon are the Necker cube, [6] and the rhombille tiling (viewed as an isometric drawing of cubes). To go further than just perceiving the object is to recognize the object. Recognizing an object plays a crucial role in resolving ambiguous images, and relies heavily on memory and prior knowledge.
