Training reduces the strength of Pavlovian biases

Full materials for the study described in: Training reduces the strength of Pavlovian biases. (Preprint, 2023). Fleming, H., Feng, G., Rutledge, R., Roiser, J., & Robinson, R.

This project comprised a baseline testing session (Orthogonal Go/No-Go Task, Affective Bias Task, Risk Taking Task, BDI, STAI), one week of training on a variant of the Go/No-Go Task, and finally a follow-up session containing the same tasks as on the first day.

These tasks have all been described previously - see citation list below.
