Social psychologists are more like to examine how external influences determine behavior. this is called ; whereas personality psychologists are likely to promote the idea that internal factors determine behavior. this is called

Attribution, Traits

Explanation:

Attribution is a social psychology term that has been used by social psychologists to define the external factor that infers the cause of behavior and events. Attribution is a phenomenon that is used by every person in their daily routine without any awareness and that infer our biases.  

For instance when you got failed in the exam then you blame the external factor such as a teacher for explaining the topic clearly.  

Traits: The traits are the factor that underlies a personality. These traits are innate. The big five factors is a test that measures the five traits of a person. These traits are introversion, extroversion, openness, conscientiousness, and agreeableness.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
