This is an array of anatomical, neuropsychological, electrophysiological, and behavioural evidence for their model.

Norman proposed a similar dual-process model of vision, and described eight main differences between the two systems consistent with other two-system models.[14]

FactorVentral system Dorsal system
FunctionRecognition/identificationVisually guided behaviour
SensitivityHigh spatial frequencies - detailsHigh temporal frequencies - motion
MemoryLong term stored representations Only very short-term storage
SpeedRelatively slow Relatively fast
ConsciousnessTypically high Typically low
Frame of referenceAllocentric or object-centeredEgocentric or viewer-centered
Visual inputMainly foveal or parafoveal Across retina
Monocular visionGenerally reasonably small effectsOften large effects e.g. motion parallax
