In psychology, the term transience refers to the decreasing ability to retrieve something that we already learned either from our long-term-memory or short-term-memory. This can happen because of brain damage but also because of lack of practice.
In this example, Amber took 4 years of Spanish and then 2 years of spanish in college but one year after she graduates she realizes that she remembers very little of the Spanish language. We can see that <u>her ability to retrieve what she learned decreased over that year,</u> therefore this would illustrate the concept of transience.
