Data are reported from 3,213 research eyewitnesses confirming that accurate eyewitness identifications from lineups are made faster than are inaccurate identifications. However, consistent with predictions from the recognition and search literatures, the authors did not find support for the "10 -12-s rule" in which lineup identifications faster than 10 -12 s maximally discriminate between accurate and inaccurate identifications (D. Dunning & S. Perretta, 2002) . Instead, the time frame that

The authors suggest several factors that are likely to moderate the 10 -12-s rule. 1 We follow convention from the processing speed literature in referring to the time that elapses from presentation of the lineup to when the participant indicates his or her choice as "response latency," rather than decision time or latency, because it incorporates both decisional and motor components.
