Someday, susan would like to participate in a marathon. even though she has been an avid long-distance runner for many years, susan has always been reluctant to sign up for a full marathon because she is usually about 10 pounds overweight. while watching a recent marathon in her city, susan noticed that a significant number of the participants were also somewhat overweight. despite their extra pounds, these runners completed the marathon and did so in a respectable amount of time. after seeing this, susan has decided to go ahead and begin training for her own marathon. this scenario provides an example of:

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.
