 beliefs about the capacity to influence and shape outcomes in our lives

Explanation:

Every individuals have our own perception to explain the outcome of our lives. Sometime we believe that the personal sitaution is totally within our control and sometimes we believe that it's not.

This personal beleif is what we referred to as our perceived contral.

In genral, perceived control can be divided into two:

- Internal locus of control

People who has internal locus of control percieved that all outcome in their lives can is depended on them, and they have the power to change their outcome. This tend to make people become motivated, constantly willing to improve, and dependable.

- External locus of control

People who has external locus of control perceived the outcome in their lives is the result of other factors beside their own. This tend to make them constantly blaming others for their failure, unmotivated , and constantly having a defeatist attitude.

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. : )
