A hitchhiker’s guide to information theoretical measures in psychology by @nielsvs.bsky.social with me and Yves Rosseel authors.elsevier.com/c/1mOwr53na-... osf.io/preprints/ps...
A hitchhiker’s guide to information theoretical measures in psychology

Niels van Santen, Yves Rosseel, Daniele Marinazzo


https://doi.org/10.1016/j.jmp.2025.102969

Highlights
• Information theory and psychology have a rich history
• Information theoretical measures can be disconnected from information theory
• These measures complement variance-based measures of variability and association
• They are more general with respect to interpretation and possible data types
• There are many extensions towards the investigation of higher-order interactions.

Abstract
In psychology, as in other sciences, information theory can be used as a tool to complement more standard regression-based methods of data analysis. It is important to see the potential of information theoretical measures as statistical tools without implying a connection to their origins in communication theory and engineering. The use of these measures may provide us with additional insights due to their sensitivity to non-linear relationships, their flexibility to the mixing of data types, and their more straightforward generalization towards investigating higher-order interactions. We briefly reintroduce information theory and compare several measures such as mutual information and co-information with correlation and regression-based methods for the investigation of variable dependence.

How should #multisensory signals be combined when they are structured in time? To explore this, we: * Introduce a new multisensory task * Compare several models TLDR: * Prior models perform suboptimally * Our new model performs ≈ an RNN, while using less than 1/10th the number of parameters.
