Workshop 'Computational Complexity of Decision Making'

Date
Tuesday, 19 November – Thursday, 21 November 2024

Location
Lecture Theatre 2, Melbourne Business School, The University of Melbourne, 200 Leicester Street Carlton.

About

A central aim of cognitive science is to understand the fundamental mechanisms that enable humans (and animals) to navigate and make sense of complex environments. As humans possess limited cognitive resources for processing vast amounts of information, understanding how humans perform complex cognitive tasks requires comprehending the underlying factors that drive information processing demands and how these affect behaviour.

The workshop "Computational Complexity of Decision-Making" (CCDM) aims to unite experts from a range of disciplines who share a unified objective: to understand the influence of information processing demands on cognition and decision-making. Our primary goal is to foster advancements in this field and speed up the path towards new discoveries.

The single-tracked, in-person workshop will facilitate a dialogue across multiple disciplines, including economics, cognitive science, computer science, psychology, and neuroscience, with the aim of achieving cross-pollination of ideas, promoting the integration of different viewpoints, and contributing to the development of mechanisms, policies, and tools that can enhance decision-making capabilities.

The workshop's objectives are multifaceted, aiming to consolidate a direction for the research program, foster interdisciplinary collaborations, increase awareness of ongoing research, and heighten understanding of the topic's importance. We welcome contributions from all fields and methodological approaches, including, but not limited to:

  • Theoretical advances incorporating tractability into models of cognition and economic theory.
  • Empirical research on the effects of information processing demands on human and animal behaviour.
  • Contributions to understanding the neural underpinnings of problem-solving and deliberation in relation to computational complexity.
  • Theoretical and empirical characterisation of task complexity and its effect on performance and strategy use.
  • Advances in information processing models and schemas such as cognitive load theory.
