Lenses and Patterns for Motivational Game Design
Consumers often choose media not just based on the media's projected mood, but also based on how that mood relates to their own moods at the moment. In Mood Management Theory, this mood alignment is referred to as semantic affinity, which describes the similarity between the consumer's current mood and the mood projected by the consumed media. Mood alteration is most effective when mood alignment is low, while mood preservation is supported by high semantic affinity, although the effect may not be as intense.
