8/ This supports a **multidimensional approach** to object space, showing that dimensions interact dynamically, depending on the visual context.
It also highlights the need for considering **temporal dynamics** to study neural processing.

6/ These results highlight two fundamental insights:
1 **Flexibility**: Object space adapts to the info available to the visual system.
2 **Temporal dynamics**: Object processing dimensions evolve rapidly over time.

5/ **Key finding #2:**
In silhouette stimuli, removing internal details flipped the result!
🔄 *Aspect ratio* became the primary dimension, stable over time, and better explained neural data during & after stimulus presentation.

4/ **Key finding #1:**
In intact stimuli, *aspect ratio* was encoded EARLY and TRANSIENTLY, while *category* and *animacy* dominated LATER and STRONGLY.
*Category* also better explained the brain's representational structure than aspect ratio.

3/ To tackle this, we presented participants with two types of object stimuli:
🔹 *Intact stimuli*: detailed objects
🔹 *Silhouette stimuli*: internal details masked
We tracked the brain's response using whole-head EEG. 🎥🧠

Still figuring things out. Looks like there's some momentum on this site.
Hello from Sydney! I'm into vision, brains, and rabbit holes.
Looking forward to connecting with #neuroscience and #psychscisky
