- How does metabolic learning shape human behaviour? In our recent study www.sciencedirect.com/science/arti..., we found that it shapes flavour preferences but, surprisingly, not action. Thread 🧵
- For animals to be motivated by a particular food, they first have to learn that it’s rewarding (containing calories, or other nutrients). In animals, metabolic learning is assessed through behaviour, but in humans it's usually measured with self-report questions – leading to mixed results.
- So we investigated whether metabolic learning actually drives differences in *human behaviour*. To do this, we made use of a phenomenon called Pavlovian-instrumental transfer (PIT), where a Pavlovian stimulus acquires incentive salience, biasing action.
