Experiment 3 used the five-sequence condition of Experiment 2, but the ISI was either 150 ms or 800 ms.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Participants reported which patient(s) were abnormal with median 95% accuracy.
