ABSTRACT
Social psychologists study the effects of one individual on another individual, and the relationships between individuals and groups. For example, social psychologists study altruistic behavior, which is an interaction between an individual and at least one other individual. They also study how one person can affect another person's attitudes, or what kind of general messages are more effective than others in changing people's attitudes. When looking at the influence of messages we might appear to be focusing on single individuals, but the influence of other individuals is implicit in the message. Social psychologists also study cognitive processes that are concerned with other individuals. For example, how are impressions formed of other people?
