Answer to Question 1
The positive face of affiliation (affiliative interest) is a concern for interpersonal relationships but not at any expense. Although people with this need value and work at maintaining good relationships, this doesn't prevent them from giving negative feedback or making tough decisions. However, the negative face of affiliation (affiliative assurance) makes people look for assurance about the security and strength of their relationships and avoid rejection. They seek approval from others and avoid issues and conflicts that might threaten relationships.
Answer to Question 2
People motivated by the positive need for power (socialized power) use it for the good of othersto make their organizations better. They are hesitant to use power to manipulate others. People with this need are less defensive and selfish and work to empower others. An example is a coach. People motivated by the negative need for power (personalized power) use it to dominate others. They have little inhibition or self-control and they exercise power impulsively. They tend to exploit and manipulate others and often satisfy their needs vicariously. An example is a dictator.
