Abstract The human response to uncertainty has been
well studied in tasks requiring attention and declarative
memory systems. However, uncertainty monitoring and
control have not been studied in multi-dimensional,
information-integration categorization tasks that rely on
non-declarative procedural memory. Three experiments are
described that investigated the human uncertainty response
in such tasks. Experiment 1 showed that following
standard categorization training, uncertainty responding
was similar in information-integration tasks and rule-based
tasks requiring declarative memory. In Experiment 2,
however, uncertainty responding in untrained information-
integration tasks impaired the ability of many participants to
master those tasks. Finally, Experiment 3 showed that the
