a) Representations in dorsal stream are sustained over time whereas those in ventral stream are short-lasting. b) fMRI has shown us that this is so named because of the neural regions where these streams start and finish - they are in the central neural regions. c) Allocentric is independent of observer's perspective, whereas Egocentric is dependent on the observer's perspective. d) Allocentric is dependent on observer's perspective, whereas Egocentric is independent of the observer's perspective.
