Darwinian domain-generality
Subtitle: The role of evolutionary psychology in the modularity debate. MA thesis (2017) by Michael Lundie, Georgia State University. The abstract:
“Evolutionary Psychology (EP) tends to be associated with a Massively Modular (MM) cognitive architecture. I argue that EP favors a non-MM cognitive architecture. The main point of dispute is whether central cognition, such as abstract reasoning, exhibits domain-general properties. Partisans of EP argue that domain-specific modules govern central cognition, for it is unclear how the cognitive mind could have evolved domain-generality. In response, I defend a distinction between exogenous and endogenous selection pressures, according to which exogenous pressures tend to select for domain-specificity, whereas the latter, endogenous pressures, select in favor of domain-generality. I draw on models from brain network theory to motivate this distinction, and also to establish that a domain-general, non-MM cognitive architecture is the more parsimonious adaptive solution to endogenous pressures.”
“I argue that endogenous selection pressures gave rise to neural network structures called a rich club/ hub core that maintains a balance between functional integration of domain-specific sub-systems and metabolic efficiency” (20). “Incorporating the notion of endogenous pressures into models of cognitive architecture helps to illuminate findings from Bullmore and Sporns’ (2012) account of cognitive economy in brain network topology. With the aim of identifying the selection pressures that shaped the precise organization of neural structures, their analysis uncovered the network structures that relay outputs between networks and efficiently process information to facilitate central cognition (2012: 338).
