Shared Emotion Geometry Across Small Language Models: A Cross-Architecture Study of Representation, Behavior, and Methodological Confounds
Researchers demonstrate that five mature small language model architectures (1.5B-8B parameters) share nearly identical emotion vector representations despite exhibiting opposite behavioral profiles, suggesting emotion geometry is a universal feature organized early in model development. The study also deconstructs prior emotion-vector research methodology into four distinct layers of confounding factors, revealing that single correlations between studies cannot safely establish comparability.
