He’d lost his appetite. The pizza he’d ordered sat untouched on the table, its cheesy aroma failing to pique his interest. Earlier that day, he’d found the note tacked to his dorm room door. "Moved on. Goodbye." Signed, only with a looping, familiar initial. Professor Harding. The sudden departure had left a void, a hollow ache in his gut.

He ran his hand through his hair, a nervous gesture he hadn't noticed he'd adopted. He hadn't been able to focus on his studies all day, the assignments seemed impossible. He slumped in his chair. He felt like his limbs were made of lead. The simple act of getting up, of walking, felt like an insurmountable effort. He wished Harding had had the decency of a phone call.

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.
