explain situations whereby instead of an incentive, there is rather a threat in place, for example, going outside during a natural disaster in order to help others.

It does not consider the cases where individuals are engaging with both extrinsic and intrinsic motivators. Developmental psychology can account for the complexities behind human motivation.
