Personal constructs influence behavior. If I see the world as a friendly place, I'll be friendly, for example.

Answer 2

I have an antisocial friend, who has an antisocial personality (look that up). She views everything that happens as a plot to get her, or to hurt her, or to take advantage of her. Her social perspective: She must manipulate, lie, cheat, steal in order to get ahead. She will do anything to control others.
After you have looked up the traits of the antisocial personality, and reflect on her behaviours listed, you should be able to answer your questions.
