Linday and wells (1985): argued that sequential better than simultaneous because witnesses making absolute rather than relative judgments of similarity in sequential: use d" as a (cid:373)easure. Gronlund (2004): found simulatensous-seq lineup difference due mostly to more conservative response criterion in sequential: get fewer hits and fewer false alarms, the actual discriminability is no different. Gronlund et al (2012): roc analysis shows sequential lineups never more accurate than simultaneous in discriminability.
