Comparing cognition across major transitions using the hierarchy of formal automata

Abstract

The evolution of cognition can be understood in terms of a few major transitions—changes in the computational architecture of nervous systems that changed what cognitive capacities could be evolved by downstream lineages. We demonstrate how the idea of a major cognitive transition can be modeled in terms of where a system's effective computational architecture falls on the well‐studied hierarchy of formal automata (HFA). We then use recent work connecting artificial neural networks to the HFA, which provides a way to make the structure‐architecture link in natural systems. We conclude with reflections on the power and the challenges of traditional thinking when applied to neural architectures.This article is categorized under: Cognitive Biology > Evolutionary Roots of Cognition Psychology > Comparative Philosophy > Foundations of Cognitive Science
