We show that during value-based decisions, humans do not always use all reward-related information to make their choice, but instead can “jump the gun” using partial information. In particular, when different sources of information were in conflict, early decisions were mostly based on fast bottom-up information, and sometimes followed by corrective changes-of-mind based on slower top-down information. This supports parallel decision processes among different information sources, as opposed to a single integrated “common currency.”
