Hermann von (*) Helmholtz was the father of the early modern science of this faculty, which is used to perceive the autokinetic effect and the phi phenomenon.
A 1982 book that purports to be a "computational investigation" of this ability treats it as an information-processing system on computational, algorithmic, and physical levels. That book was authored by David Marr, who names a top prize in the computer field of this ability. Before moving onto investigating phantom limbs, V.S. Ramachandran investigated this ability, which yielded results in dynamic aftereffects. The ancient Greeks were split on whether this ability was governed by the "emission theory" or the "intromission theory." Hermann von (*) Helmholtz was the father of the early modern science of this faculty, which is used to perceive the autokinetic effect and the phi phenomenon. For 10 points, name this faculty that depends on the perception of light.
