ABSTRACT
As behavior designers, artificial intelligence (AI) programmers have very similar issues to deal with; they have to make their behaviors “readable” by players in different situations and have their players recognize and understand the behavior. This chapter encourages AI programmers to think about the aspect of their behavior design and to ground AI programmers in a sample of the psychological aspects that come into play from the player's perspective. The characters themselves were portrayed using different clothing and gender options, with the aim of the study being to understand more about the effect of the communication mode on the choice. The chapter convinces AI programmers that many of the psychological tools they can use to affect players' perceptions function at a high level of abstraction and can often be implemented with very minimal development cost. Psychology itself is an ongoing area of research and we are only just beginning to investigate the psychology involved in games.
