Subjects make decisions according to event rates, not event counts. a, Example subject. Abscissa indicates the number of event counts. Each colored line shows the subject's performance for trials where the event count on the abscissa was presented over the duration specified by the labels. For a given event count (11 events, black arrow) the subject's choices differed depending on trial duration. n = 3656 trials b, Same data and color conventions as in a except that the abscissa indicates event rate instead of count. For a given event rate (11 events/s, black arrow), the subject's choices were very similar for all trial durations. c, d, Data for four subjects; conventions are the same as in a and b. n = 9727 trials. Prop, Proportion.
