Susan has been hauling buckets full of berries to the kitchen where other classmates are preparing to make pies. On the last trip she got caught on a raspberry cane and tore a runner in her tights. She imagines other students are looking at her and noticing the line up the back of her leg. This aspect of adolescent egocentrism is known as the imaginary audience.

The answer is imaginary audience.

Explanation:

Imaginary audience is a term that describes the state which an individual believes or imagines that there are a number of persons or people enthusiastically watching or listening to him or her.

This kind of state is most common with adolescents (which Susan is most likely one). However, the fantasy of an imaginary audience can be exhibited by people of any age whether in childhood, adolescence and adulthood.
