In the last chapter, we saw how our social natures mean that we tend, on the whole, to be cooperative and compliant with other people, although that isn’t always the case. We respond differently to different people, and sometimes to the same people but in different situations. Sometimes, circumstances mean that we react defensively or aggressively towards others, and sometimes, too, we find that we just don’t like someone. In this chapter, we will be exploring how we react to other people. We will begin by looking at some of the processes involved in person perception, and then move on to what psychologists have discovered about liking and attraction.
