Ying Yang @yyagpsy.bsky.social · 07/08/2025Check our comment about number sense: likely innate, surely not visual. 010
Ying Yang @yyagpsy.bsky.social · 01/06/2025Overall, these findings reveal a multifaceted neural representation of numerosity across sensory modalities and presentation formats. 7/7 000
Ying Yang @yyagpsy.bsky.social · 01/06/2025Next, we used RSA to characterize the fine-grained representational structure. Partial correlation results revealed a posterior-to-anterior gradient: posterior regions coded more for modality, while anterior regions coded more for format. 6/7 100
Ying Yang @yyagpsy.bsky.social · 01/06/2025This pattern may reflect everyday statistics: numerosities within the same format—especially sequential—often co-occur, while cross-format pairings are rare. The brain may internalize these regularities, grouping numerosities by format even across senses. 5/7 100
Ying Yang @yyagpsy.bsky.social · 01/06/2025Cross-decoding in conjunction-defined ROIs revealed shared representations only when numerosities shared temporal structure—even across senses. No significant decoding emerged across formats, even within the same modality. 4/7 100
Ying Yang @yyagpsy.bsky.social · 01/06/2025Searchlight MVPA identified regions encoding numerosity per condition. Conjunction analysis revealed overlap decoding numerosity across modalities and formats. 3/7 100
Ying Yang @yyagpsy.bsky.social · 01/06/2025Humans can perceive numerosity across senses and contexts, but how and where the brain abstracts numerical information from low-level input remains debated. We investigate this question by studying numerical stimuli spanning sensory modalities and presentation formats. 2/7 100
Ying Yang @yyagpsy.bsky.social · 01/06/2025🎉🎉Happy to share the first preprint of my PhD project with @olicolli.bsky.social ! We explored how numerosities across senses (👁️ and 👂) and presentation formats (spatial or temporal) are organized in the brain. www.biorxiv.org/content/10.1... 1/7🧵biorxiv.orgMultifaceted brain representation of numerosity across the senses and presentation formatsHumans can extract numerosity from different senses and a variety of context.

Ying Yang @yyagpsy.bsky.social · 18/05/2025It’s been amazing so far to meet so many inspiring people and talk science at #VSS2025. Tomorrow I’ll be giving a talk in Talk Room 2 on how the brain abstracts numerals from various sensory inputs. Come check it out! 041
