Table 2 Sensitivity (d’), hits, and false alarms for the change deafness (AX same/different) task. d’ calculations are based on a differencing model (Macmillan & Creelman, 2005)

  1. aFalse alarms were calculated based on no change (catch trials). Catch trials do not include a change type (add, remove) or a change level (+3, 0, –3) manipulation, as there is no change to be manipulated. Thus, the False alarm rate is the same across all condition bins
