In interpersonal conflict, you are in conflict with other individuals. This is considered a major level of conflict and can occur between co-workers, siblings, spouses, roommates and neighbors, reports Lewicki, Barry, and Saunders, writing in "Essentials of Negotiation." This is the form of conflict most people have in mind when they think about being in conflict.
In the other hand According to Lewicki, Barry, and Saunders,
intrapersonal conflict is also called intrapsychic conflict. It occurs within
you. This conflict can develop out of your own thoughts, ideas, emotions,
values and predispositions, reports Lewicki, Barry, and Saunders. Intrapersonal
conflict occurs when you internally argue with yourself about something, such as
when you want a new pair of shoes but you know you should not spend the money
on them.
