Abstract: This paper presents a new methodology for\nexamining the phenomenon of subitizing. Subjects\nwere presented with a standard numerosity-detection\ntask but for a range of presentation times to allow\nTask-Accuracy Functions to be computed for\nindividual subjects. The data appear to show a\ncontinuous change in processing for numerosities\nfrom 2 to 5 when the data are aggregated across\nsubjects. At the level of individual subjects, there\nappear to be qualitative shifts in enumeration\nprocessing after 3 or 4 objects. The approach used in\nUiis experiment m a y be used to test the claim that\nsubitizing is a distinct enumeration process that can\nbe used for small numbers of objects.
