Substituting the Senses

Check out this essay forthcoming from the power team of Clark, Kilverstein and Farina.

Sensory substitution devices are a type of sensory prosthesis that (typically) convert visual stimuli transduced by a camera into tactile or auditory stimulation. They are designed to be used by people with impaired vision so that they can recover some of the functions normally subserved by vision. In this chapter we will consider what philosophers might learn about the nature of the senses from the neuroscience of sensory substitution. We will show how sensory substitution devices work by exploiting the cross-modal plasticity of sensory cortex: the ability of sensory cortex to pick up some types of information about the external environment irrespective of the nature of the sensory inputs it is processing. We explore the implications of cross-modal plasticity for theories of the senses that attempt to make distinctions between the senses on the basis of neurobiology.



Well, this article was inevitable – first mentioned here). Francis Heylighen has been talking about this for a few years now as has myself in discussing Hayek, distributed cognition and co-evolved mind and sociality not to mention my ongoing interest in stigmergy which I argue is a species of EM.

Abstract: This article explores the notion of the Web-extended mind, which is the idea that the technological and informational elements of the Web can sometimes serve as part of the mechanistic substrate that realizes human mental states and processes. It is argued that while current forms of the Web may not be particularly suited to the realization of Web-extended minds, new forms of user interaction technology as well as new approaches to information representation do provide promising new opportunities for Web-based forms of cognitive extension. In addition, it is suggested that extended cognitive systems often rely on the emergence of social practices and conventions that shape how a technology is used. Web-extended minds may thus depend on forms of socio-technical co-evolution in which social forces and factors play just as important a role as do the processes of technology design and development.

Keywords: cognition, cognitive extension, cognitive technology, extended mind, Internet, linked data, Web science, World Wide Web.


Stigmergy 3.0: From Ants to Economies

Marge and my intro now available as an uncorrected proof. Stay tuned for the rest of the papers comprising this special issue.

According to Andy Clark “[M]uch of what goes on in the complex world of humans, may thus, somewhat surprisingly, be understood in terms of so-called stigmergic algorithms” (Clark, 1996, p. 279; 1997, p. 186). Pierre-Paul Grassé, the brilliant mind who first conceptualized the notion probably wouldn’t disagree (Grassé, 1959). Grassé was as much a zoologist as he was an entomologist. Under his editorship the monumental (17-volume) Traité de Zoologie, Anatomie, Systématique, Biologie was guided.
