Answer:
differential susceptibility
Explanation:
Differential susceptibility model was proposed by Jay Belsky, this theory explains the way two different individuals respond to the effect of their environment. In this theory there is the plastic group (which Marissa belong to) and the fixed group (which Jessica belong to). The plastic group are largely affected by the positive and negatives in their environment when compared to the fixed group.
The theory explains that people do not vary in the level at which they become vulnerable to the negative effect in their environment but that generally it is based on their developmental plasticity.
