A doctor’s visit, prompted by a persistent rash, led to a startling revelation. The doctor, eyes wide, mentioned a rare genetic anomaly. As she left the office, she bumped into a woman in the waiting room. The woman was holding a tissue to her mouth, and the movement looked clumsy and heavy.

"They just told me," the woman whispered, "that I have… this thing."

Role in Research

This story is one of 1,000 stories generated for the emotion depressed. 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 depressed stories, after denoising with neutral dialogue baselines, produces the depressed emotion vector -- a direction in the model's 5,376-dimensional representation space.
