Although linked, researchers have long distinguished appetitive from consummatory phases of reward processing. Recent improvements in the spatial and temporal resolution of neuroimaging techniques have allowed researchers to separately visualize different stages of reward processing in humans. These techniques have revealed that evolutionarily conserved circuits related to affect generate distinguishable appetitive and consummatory signals, and that these signals can be used to predict choice and subsequent consumption. Review of the literature surprisingly suggests that appetitive rather than consummatory activity may best predict future choice and consumption. These findings imply that distinguishing appetite from consumption may improve predictions of future choice and illuminate neural components that support the process of decision making.
