The perception–action model proposes that vision for perception and vision for action are subserved by two separate cortical systems, the ventral and dorsal streams, respectively [Milner, A. D., & Goodale, M. A. (1995). The visual brain in action (1s... Read More about Both egocentric and allocentric cues support spatial priming in visual search.
