The effects of delay on the performance of computerized feature systems for identifying suspects
In suspect identification, witnesses examine photos of known offenders in mugshot albums. The probability of correct identification deteriorates rapidly, however, as more photos are examined. Computerized feature systems, which display mugshots in order of similarity to witness descriptions increase success by reducing the number of mugshots examined. Previous experimental tests failed to examine the effects of delay (in eliciting witness descriptions) on recall memory and system performance, as well as the effects of number of raters per mugshot, and live target suspects (rather than using photos of men as targets). In two studies (one with live and one with photo target suspects), subject witnesses described targets after delays varying from several days up to four weeks. Delay had no effect on the number of photos examined, although in the fourth week the accuracy of witness feature descriptions of suspects began to deteriorate. Two raters per mugshot significantly improved performance. More raters did...
