“…However, there are several reasons why the effect observed in the experiments presented here must be at least partially mediated by input from the ventral pathway. First, the effect cannot be explained in terms of egocentric oculomotor coordinates, given that representations of oculomotor movements appear to be short-lived and are not stored (Goodale & Humphrey, 1998). Second, the results of Experiment 5 suggest that ®xations to distinct locations in space are not required to cause systematic saccades to these blank regions.…”

It has been argued that the human cognitive system is capable of using spatial indexes or oculomotor coordinates to relieve working memory load (Ballard, D. Here we examine the use of such spatial information in memory for semantic information. Previous research has often focused on the role of task demands and the level of automaticity in the encoding of spatial location in memory tasks. We present ®ve experiments where location is irrelevant to the task, and participants' encoding of spatial information is measured implicitly by their looking behavior during recall. In a paradigm developed from Spivey and Geng (Spivey, M. J., & Geng, J. (2000). submitted for publication), participants were presented with pieces of auditory, semantic information as part of an event occurring in one of four regions of a computer screen. In front of a blank grid, they were asked a question relating to one of those facts. Under certain conditions it was found that during the question period participants made signi®cantly more saccades to the empty region of space where the semantic information had been previously presented. Our ®ndings are discussed in relation to previous research on memory and spatial location, the dorsal and ventral streams of the visual system, and the notion of a cognitive-perceptual system using spatial indexes to exploit the stability of the external world. q

“…A division has been suggested between two main processing streams, a ventral stream leading from V1 to the inferotemporal cortex (IT), where shape processing, leading to object recognition, seems to take place (Ungerleider and Mishkin, 1982), and a more dorsal stream, going to the parietal cortex, that may be related to object-directed action (Goodale and Humphrey, 1998).…”

“…Later, this learning can be used to activate a population of neurons to orient the body toward a target or to activate few neurons representative of a class to be recognized, but in both cases, the same kind of distributed network establishing relations between poles of representation is exploited (cf Table 2). This unified view of coordination between poles of representation promotes the principle of purposive perception [15]: the axes of processing depend on the purpose of the poles to be associated and consequently determine the hints to be extracted in the intermediate representations.…”

Human communication emerges from cortical processing, known to be implemented on a regular repetitive neuronal substratum. The supposed genericity of cortical processing has elicited a series of modeling works in computational neuroscience that underline the information flows driven by the cortical circuitry. In the minimalist framework underlying the current theories for the embodiment of cognition, such a generic cortical processing is exploited for the coordination of poles of representation, as it is reported in this paper for the case of visual attention. Interestingly, this case emphasize how abstract internal referents are built to conform to memory requirements. This paper proposes that these referents are the basis for communication in humans, which is firstly a coordination and an attentional procedure with regard to their congeners.
