The autumn leaves swirled around Daniel's feet as he browsed the yard sale. He had a deep sigh, a familiar ache in his chest. Then, there he was: Bartholomew, his childhood teddy bear, sitting forlornly amongst a pile of discarded trinkets.

A wide smile spread across Daniel's face, his eyes crinkling at the corners. He felt a bubbly anticipation.

He examined Bartholomew, then held the bear close, feeling a rush of affection. He knew exactly what he would do: he would spend the entire evening re-reading his old favourite books, with Bartholomew by his side, just like when he was a child. He felt a thrill of excitement at the prospect.

Role in Research

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