She’d dedicated her entire semester to this project; all-nighters, endless revisions, and sacrifices of her social life. The feedback, a cascade of criticisms, felt like a personal attack.

Her hands, clammy and cold, gripped the edge of the desk. A strange numbness spread through her limbs. She felt disconnected from her body, as if observing herself from a great distance. Her breath hitched in her throat, and a knot formed in her stomach.

Role in Research

This story is one of 1,000 stories generated for the emotion dumbstruck. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 dumbstruck stories, after denoising with neutral dialogue baselines, produces the dumbstruck emotion vector -- a direction in the model's 5,376-dimensional representation space.
