The consequences of an action influence the frequency with which that action is displayed in the future. what does this describe?

This is law of effect.

Explanation:

The "law of effect" is a principle developed by "Edward Thorndike". It is the principle on behavioral conditioning, which means that if a response has a pleasing effect are likely to occur again. And if a reaction doesn’t produce satisfying effect would have less frequency in future. For example, if an employee is praised by the boss for starting his work early, it is likely that the employee’s behavior will repeat in future.

Thus, the given statement is law of effect.

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. : )
