“He’s…going?” David repeated the words, his voice a low monotone. His advisor, Professor Lee, was leaving. The implications were vast, complex, terrifying. His palms were slick with sweat.

He spent the rest of the day in a stupor, walking through campus aimlessly. He barely registered the passing students, the familiar landmarks. Everything felt distant, like an imperfect copy of the real thing.

He couldn't bring himself to open his thesis. The blank page, once a challenge, now represented a monumental task.

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.
