Personal Relationships
Personal relationships involve the everyday associations we have with others. Principal factors contributing to the success or failure of personal relationships are how interpersonal relationships are formed, what they do to us once they are formed, and what people do in relationships.

To understand the complexities of a relationship, it's necessary to examine the observable qualities of relationships: the actual behaviors of persons in relationships, the stimuli that trigger various reactions (including reactions such as attraction, anger, and satisfaction), the sequences of interactions between persons involved in relationships (their communication strategies), and the manners through which individuals express themselves and their intentions (with a focus on emotions). Other issues include personality variables, deviance and relationships, power and authority in relationships, and clinical topics such as loneliness.

The mental activities involved in relationships are especially important for understanding how persons make conclusions and judgments about one another, how emotions are experienced, and how decisions are made to attempt to influence one another or simply to live up to another's expectations.
