- •Positive affect (PA) might be involved in resilience against chronic pain.
- •Stronger increases in PA are associated with steeper fear generalization gradients.
- •This is due to better fear inhibition in response to movements resembling the original safe movement.
- •Steeper generalization gradients are not associated with more spreading of fear inhibition in response to movements resembling the original painful movement.
- •PA may improve safety learning by promoting generalization from safe to novel movements.
