List and explain the five factors that influence relationship formation, providing an example for each

What will be an ideal response?

1. Personality traits: We look for personalities that are similar to ours. These personalities emerge as we get to know one another; sometimes we find we've misperceived the other's personality, which can cause the relationship formation to halt. Example: As an agreeable person, I was attracted to a friend with a similar personality, but I found later than she was actually neurotic, which was so difficult for me to manage that I ended the friendship.
2. Physical appearance: We're attracted to people who are physically attractive, even for friendships and business relationships. Example: Numerous studies—often replicated on TV news magazine shows, such as ABC's 20/20—show that more attractive people earn higher grades, are hired more frequently over equally qualified others, and even earn higher tips than those who are not as physically blessed.
3. Similarity-Complementarity: We're attracted to people who have more things in common with us (similarity), ranging from shared demographics to shared physical characteristics. But we're also attracted to those whose strengths balance our weaknesses (complementarity). Example: My best friend and I are the same age and gender, and have similar senses of humor (similarity); however, she is high strung, while I am easy-going, opposite traits that work to offset each others' weaknesses (complementarity).
4. Proximity: We develop relationships with people who are near us, either physically or psychologically. Example: My best friend and I were in the same grade at school and went to the same college after we graduated. Now that we live apart, we have to use mail, the phone, and electronic communication to remain psychologically close.
5. Technology: We exchange many electronic messages every day, proving that we are using CMC to facilitate interpersonal relationships. Example: I have reignited old friendships through Facebook.
