New preprint! What the eyes do when searching for a visual target reveals the psychological similarity between objects, just like more classic (but much longer & tedious) tasks like triplet odd-one-out and direct comparison. www.biorxiv.org/cgi/content/... #BRAINFLOW @upcite.bsky.social @cnrs.fr

Eye movements reveal representational geometry

Mental representations are the explanatory construct of the cognitive sciences, but there is no widely accepted characterization of how they cause behavior. Visual representational geometry can be quantified by similarity scores, but almost all methods require an explicit judgment. To examine how representations cause behavior by varying task demands, observers must perform different tasks while continuously reporting similarity, leading to dual-task interference. This study develops scanpaths as an implicit similarity measure, and uses representational similarity analysis to validate it. Observers searched for a target; fixations on distractors may reveal similarity. Similarity was also quantified by an odd-one-out task in the same participants, and ratings from different participants (Jiang et al. 2022). Representational geometries between tasks correlated. A generative model predicted first fixations in novel data. This double validation of the scanpath method opens the door to examining the causality of representations by determining if and how they vary with task demands. ### Competing Interest Statement The authors have declared no competing interest.

You think you can(not) multitask? Turns out that the sensorimotor system is flexible and intelligent when perceiving and acting on the environment in parallel. Check out one of the main projects from my @dfg.de funded Walter Benjamin!

#JNeurosci: Findings from Fooken et al. reveal how the brain integrates knowledge of sensorimotor demands with predictions about environmental events to flexibly manage competition for gaze between action and monitoring tasks. https://doi.org/10.1523/JNEUROSCI.2157-25.2026

Why is touch perceived as weaker during movement? In our new preprint 📝, we examine tactile suppression during reaching. Using optimal control theory, we show that tactile suppression reflects dynamic, uncertainty-dependent integration of forward model predictions and sensory feedback.

Finished reading „The Dispossessed“ by Ursula Le Guin. Such a deep book. “No man earns punishment, no man earns reward. Free your mind of the idea of deserving, the idea of earning, and you will begin to be able to think.”
