James Paul Gee introduced the idea of affinity groups in his seminal What Video Games Have To Teach Us about Language, Learning, and Literacy (Gee, 2007). It is defined as the people associated with a given semiotic domain. That basically is a domain in which people use particular symbols or language to communicate and interact. We’re already well used to the concept, even if we don’t realize it. A given academic discipline, for example, will have its own vocabulary and, in that context, use language in a particular way, even if others use it differently in another context. It’s all about situated cognition and situated meaning. Games and their communities will have their own semiotics and constitute a semiotic domain. Members of an affinity group will have a way to recognize others who belong and to assess what counts as acceptable or recognizable within that semiotic domain.
