In this thesis I examined the coding mechanisms that underlie expression perception. My findings support a two-pool opponent coding system, with expressions coded relative to an implicitly-represented norm. I compared two potential contenders for this norm, the average expression and the neutral expression, and found that both may be equally good approximations of the true norm. I also explored the time course of the aftereffect produced by adaptation to expressions, and found that this expression aftereffect is surprisingly persistent. Together these studies form a systematic investigation of the way that facial expressions are visually represented.
