Unraveling the Mysteries of Cognitive Constraints

Published on April 10, 2023

Imagine you are a master chef, concocting a mouthwatering recipe. But here’s the catch: you have limited ingredients and tools at your disposal. In the world of cognition, our brains face a similar challenge. All forms of thinking, whether natural or artificial, are bound by constraints dictated by our brain’s computing architecture. This letter dives deep into the enigma of these cognitive constraints. It explores why our cognitive abilities are subject to limitations and delves into the tradeoffs and compromises that neural architectures must make, which ultimately shape the bounds of rationality and optimality. The authors unlock clues along the puzzle edge, shedding light on the computational aspects of cognition and proposing that some of these bounds can be modified by cognitive processes. By understanding the nature of these constraints and how they can be altered, we gain a more holistic perspective on the capabilities of our minds. Curious to unravel the mysteries? Dive into this fascinating research to uncover the secrets behind cognitive boundaries!

Abstract
All forms of cognition, whether natural or artificial, are subject to constraints of their computing architecture. This assumption forms the tenet of virtually all general theories of cognition, including those deriving from bounded optimality and bounded rationality. In this letter, we highlight an unresolved puzzle related to this premise: what are these constraints, and why are cognitive architectures subject to cognitive constraints in the first place? First, we lay out some pieces along the puzzle edge, such as computational tradeoffs inherent to neural architectures that give rise to rational bounds of cognition. We then outline critical next steps for characterizing cognitive bounds, proposing that some of these bounds can be subject to modification by cognition and, as such, are part of what is being optimized when cognitive agents decide how to allocate cognitive resources. We conclude that these emerging views may contribute to a more holistic perspective on the nature of cognitive bounds, as well as their alteration subject to cognition.
