Dates: July 25 to July 29, 2025 (paper and poster sessions July 26 to July 28) 

Venue:  The Ohio State University, Ohio Union and Blackwell Inn

The MathPsych/ICCM 2025 organizing committee invites abstracts for talks, posters, and symposia to be presented at the 58th Annual Meeting of the Society for Mathematical Psychology (MathPsych) and the 23rd International Conference on Cognitive Modeling (ICCM) at The Ohio State University in Columbus, Ohio, USA.

The dates of the conference are July 25 to 29, 2025. July 25, 2025, will be dedicated to workshops, and a Women of Mathematical Psychology-sponsored Professional Development Symposium Event. Talks and keynotes will take place July 26 to 28, 2024. The annual ACT-R Workshop will also be held at Ohio State University on July 29, 2025. 

 

The conference showcases leading research on mathematical and computational theories of human cognition. We welcome contributions from the complete spectrum of formal approaches to modeling cognition, including connectionism, symbolic modeling, dynamical systems, Bayesian modeling, and cognitive architectures.

Conference workshops. There will be two workshops hosted on the morning of July 25th, one MathPsych and one ICCM hosted workshop. Both will take place at the Blackwell Inn & Conference Center. Here are the descriptions of the two workshops -- be sure to indicate which ones you would like to attend when you register for the conference!

Workshop #1. Bringing Cognitive Modeling Up to Speed with Simulation-Based Inference, a tutorial approach: Simulation based inference (SBI) is an emerging and transformative paradigm for statistical inference, driving model-based insight in a variety of research domains. Traditional statistics education implicitly relies on likelihood functions as the backbone of parameter inference for computational models. However, deriving analytical likelihoods is often infeasible, even for models that are simple to simulate. SBI circumvents this challenge by enabling parameter inference directly from simulation code, eliminating the need for explicit likelihood derivations. Recent advances in computational statistics, deep learning, and user-friendly software have supercharged SBI. In psychology and cognitive science, these developments have made it possible to infer parameters for a wide range of cognitive models. Many of these models were of long-standing theoretical interest but remained untestable due to the lack of efficient inference methods. As a result, our research community has now gained access to a much larger array of computational models that can be routinely tested against data. This workshop aims to guide participants from principles to practice. It will provide attendees with a comprehensive overview of the landscape of SBI techniques as well as a hands-on path from simulation to parameter estimation, using a large basket of methods and covering multiple practical use cases. Participants will gain a clear understanding of the current ecosystem of tools for SBI, the strengths and limitations of specific SBI techniques for different use cases, and the potential synergies between conceptual approaches and existing software libraries.

Workshop #2. High performance computing for dynamical systems and Bayesian estimation with on-demand computing resources: Cognitive modeling often requires high computational resources. Complex models must often be run for long periods of time, and experiments must often be repeated. Many researchers limit their models and designs to meet these computational restrictions, however using the right tools, models can be distributed and scaled to meet the computational requirements of the most complex models. In this workshop, we aim to show a flexible and scalable modeling environment that can be used in both local settings, and High Performance Computing (HPC) Clusters. We will present and make use of the Julia programming language, some of its tools for modeling dynamical systems, and Bayesian parameter estimation, as well as the methods to offload workloads from your desktop to HPC clusters.
