Answer:
Social modeling.
Explanation:
Social modeling, also called social learning, refers to an individual's ability to reproduce observed behavior, similar to what happened to Susan after seeing the success of overweight people in the marathon. This type of learning is distinguished from other types of learning in that it is based on imitation and, therefore, in the fact that without it such behaviors would hardly be apprehended.
Social modeling is based on the premise that learning can occur through direct experiences, that is, through experiences and models of observing the behavior of other individuals and the rewards they receive.
