Stronger evidence for the implicit learning of base rates comes from the learning phases of categorization experiments. When asked verbal questions at the end of the experiment, however, subjects showed misuse of the base-rate information. That is, whatever was learned was learned by the observation of many stimulus events, and competence in using that acquired knowledge would not be demonstrated by reporting to an experimenter, but rather would be evinced by responding appropriately to that same stimulus when it next appeared in the environment.
