There are two types of learning that occur in development stages of adulthood.
Informational Learning: This type of learning is when a person learns a new skill.
Transformational Learning: This type of learning is when a person can alter how they see something and often see a bigger perspective.
The first is more horizontal thinking and the latter is more vertical thinking. It seems the more you can learn horizontally, the more opportunity you have to learn vertically. Both of these learnings cause a person to evaluate the way they see themselves within their current environments. If a person doesn't like their identity within their current environment, they look for making a change.
