Due to teaching diligencies, I wasn't able to assist VSS this year, but all talks and posters seems once again pretty amazing !! Wishing everyone a nice @vssmtg.bsky.social 2026. What a wonderful conference ^^

#BIDS has been extended to #EyeTracking data! There is now a standard for organizing and sharing eye tracking, covering gaze position, pupil size, meta data, messages, and more. Great news for #OpenScience! 🎉 Martin Szinte et al: www.biorxiv.org/content/10.6...

6. Lastly, we found reliable results across two different populations from the US and Mexico. We also computed our data across different distance metrics, correlation methods, and statistical methods. so we are looking forward to feedback! To learn more, check out our preprint!😊

5. Finally, we trained CNNs and algorithmic models on our image dataset (with 40 categories) on object-based properties, and we found that only supervised and models with high performance correlate significantly with object-based and neural spaces.

Alejandro Gamba (he/him) @alejogamba.bsky.social · 08/07/2025
4. When looking at their 2nd-level bimodal correlations, we found that only object-based properties correlate significantly with neural regions (being more strongly correlated with visual areas than associative areas). Our behavioral and bimodal results were supported by MDS.

Alejandro Gamba (he/him) @alejogamba.bsky.social · 08/07/2025
3. We computed traditional noise ceilings across brain regions, but also added analyses to compute noise ceilings per ROI, which we believe may be a more informative way of contrasting explainable variance across models to show how it relates to bimodal correlations :)
100
Alejandro Gamba (he/him) @alejogamba.bsky.social · 08/07/2025
2. Neurally, we evaluated 11 ROIs between visual and pre-frontal regions to compare the granularity of their representational spaces, and show lower across-subjects variance in visual regions compared to prefrontal areas, which is an important factor for bimodal correlations ;)

1. By collecting similarity jugments for multiple object properties (e.g. category, shape), subjective feelings (scariness and preference), and more abstract ratings (general similarity), we identified what we call an "object-based" space and a "subject-based" space.

3. We advocate for the usage of Noise Ceilings per ROI (rather than the whole group as usual) to understand better behavior-Neural correlations at a 2nd-level.

Alejandro Gamba (he/him) @alejogamba.bsky.social · 02/04/2025
Main take-home points: 1. There are at least 2 mental representational spaces across properties. 2. Only "object-based" representational spaces & high-performance CNNs correlate significantly with neural ROIs.

A potential issue might be to control for the angular separation in the internal stimuli condition to attribute/assure repulsion or not :)
