Symbols and quantities in parietal cortex: elements of a mathematical theory of number representation and manipulation
In this chapter, I put together the first elements of a mathematical theory relating neurobiological observations to psychological laws in the domain of numerical cognition. The starting point is the postulate of a neuronal code whereby numerosity—the cardinal of a set of objects—is represented approximately by the firing of a population of numerosity detectors. Each of these neurons fires to a...

How do symbols affect 3-to 4-year-olds' executive function? Evidence from a reverse-contingency task. Symbols and executive function 2 Abstract In two experiments 330 3-to 4-year-olds competed for stickers in a game where the optimal response strategy was to point to an empty box that their opponent would receive in order to obtain a baited box for themselves. When the baited box contained stic...
متن کاملAsymptotics and 6j-symbols
Recent interest in the Kashaev-Murakami-Murakami hyperbolic volume conjecture has made it seem important to be able to understand the asymptotic behaviour of certain special functions arising from representation theory — for example, of the quantum 6j -symbols for SU(2). In 1998 I worked out the asymptotic behaviour of the classical 6j -symbols, proving a formula involving the geometry of a Euc...
متن کاملEigenbehavior and Symbols
In this paper I sketch a rough taxonomy of self-organization which may be of relevance in the study of cognitive and biological systems. I frame the problem both in terms of the language Heinz von Foerster used to formulate much of second-order cybernetics as well as the language of current theories of self-organization and complexity. In particular, I defend the position that, on the one hand,...
