“…Dissociation between perception and action can be found in many studies (Goodale & Milner, 1992;Loomis et al, 1992;Smeets & Brenner, 1995;Philbeck et al, 1997;Fukusima et al, 1997;Kelly, Loomis & Beal, 2004;Kudoh, 2005). However, there is also evidence against this dissociation, with many papers trying to reconcile the pathways (Kugler & Turvey, 1987;Goodale & Humphrey, 2001, Norman, 2002. In this study, results might sustain the hypothesis of the dissociation between perception and action, with the "middle rule" being related to a perceptual strategy, while the navigation from "landmark to landmark" implies an action strategy.…”

“…In the context of visual control of the action, Goodale and Humphrey (2001) state that perceptual tasks differ from motor tasks as a consequence of information processing in two independent neural pathways: the ventral (related to perception, e.g. object recognition) and the dorsal (related to directed action, e.g.…”

“…The vision for perception system has evolved in addition to the vision for action system (reviewed in Rossetti and Pisella, 2002; Glover, 2004; Goodale and Milner, 2004; Goodale and Humphrey, 2005; Goodale, 2007; Umiltá, 2007). The fact that a second visual system with different properties has evolved to provide suitable information for conscious perception must mean there is biological value in perceptual systems.…”

This research is an investigation of whether consciousness—one's ongoing experience—influences one's behavior and, if so, how. Analysis of the components, structure, properties, and temporal sequences of consciousness has established that, (1) contrary to one's intuitive understanding, consciousness does not have an active, executive role in determining behavior; (2) consciousness does have a biological function; and (3) consciousness is solely information in various forms. Consciousness is associated with a flexible response mechanism (FRM) for decision-making, planning, and generally responding in nonautomatic ways. The FRM generates responses by manipulating information and, to function effectively, its data input must be restricted to task-relevant information. The properties of consciousness correspond to the various input requirements of the FRM; and when important information is missing from consciousness, functions of the FRM are adversely affected; both of which indicate that consciousness is the input data to the FRM. Qualitative and quantitative information (shape, size, location, etc.) are incorporated into the input data by a qualia array of colors, sounds, and so on, which makes the input conscious. This view of the biological function of consciousness provides an explanation why we have experiences; why we have emotional and other feelings, and why their loss is associated with poor decision-making; why blindsight patients do not spontaneously initiate responses to events in their blind field; why counter-habitual actions are only possible when the intended action is in mind; and the reason for inattentional blindness.

“…The ventral stream flows from the primary visual cortex to the inferotemporal cortex and is primarily involved in transforming visual information into object recognition and perceptual representations. The dorsal stream, which projects from the primary visual cortex to the posterior parietal cortex, uses information about an object located in extrapersonal space to direct behavioral interactions, such as a reach, with that object (Goodale & Humphrey, 2001). The ventral and dorsal streams then project to the orbitofrontal (Merigan & Maunsell, 1993;Wilson, Scalaidhe, & Goldman-Rakic, 1993) and dorsolateral prefrontal (Barbas & Pandya, 1989) cortices of the prefrontal lobe, respectively.…”
