One study in our lab [9] provided direct support for a dissociation between vision-for-perception in the ventral stream and vision-for-action in the dorsal stream.
Of course, if participants see differently there is a fresh stream of possibilities for action – depending on what they see and their value system in relation to what they see happening, they will act accordingly.
By and large, it was a wretched year for Hollywood's major studios, with a steady stream of action movies and comedies performing belly flops into empty pools.
WASHINGTON -- For all the stagnation in Congress, there's a constant stream of action on one front: Judicial nominations.
In addition, the strong link found between perception of a visual illusion and visuomotor action provides additional support to the view that the original, controversial proposal by Goodale and Milner (1992) of two separate and distinct visual streams for perception and visuomotor action should be re-evaluated.
Goodale and Milner [ 5, 12] have proposed a dichotomy whereby the ventral stream handles vision for perception, whilst the dorsal stream is a non-conscious vision for action pathway.
These results and others [e.g. 16], [18], [e.g. 33], [34] thus question the original, controversial proposal by Goodale and Milner [11] of two separate and distinct visual streams for visual perception and visuomotor action.
In this paper, we propose a global spatial-temporal three-stream CNNs architecture, which is able to be used for action feature extraction.
Much evidence supports a 'two stream' hypothesis whereby the visual processing involved in preparing for action is conducted by a different neural pathway from that involved in simple identification of objects.
The most parsimonious explanation of our results is that visuomotor actions are directed by the visual system without the need to invoke two wholly separate pathways for action and perception in the dorsal and ventral streams respectively.
