Answer:
Generativity
Step-by-step explanation:
Erik Erikson proposed a theory of psychosocial development that goes through all of the individual lifespan on different stages.
Generativity versus stagnation is the seventh of eight stages of Erik Erikson's theory of psychosocial development.
This stage takes place during middle adulthood (ages 40 to 65 yrs). People going through this stage have a feeling to create or nurture things that will outlast them, often having mentees or creating positive changes that will benefit other people (like children or grandchildren). Through this generativity we develop a sense of being a part of something bigger.
When people don't find a way to contribute to the world, they become stagnant and feel unproductive.
In this example, Olivia is 46 and wants to create a mentoring program at her company, thus, she has a feeling to create something that will outlast her by having mentees and passing along her knowledge.
Thus, we can conclude that Olivia is likely experiencing Generativity.
