Abstract

The current study investigated whether small differences in the background colours between the lineup members would influence identification accuracy of own-race and other-race faces. Using the well-established 1-in-10 paradigm, half of the array faces had exactly the same backgrounds, and half were on backgrounds of slightly different hues of green. For target present arrays, participants were more accurate at identifying own-race faces when compared with the other-race faces when all backgrounds were the same. However, when backgrounds had slightly different hues, there was no difference in how accurate people were at identifying faces from both races. For target absent arrays, participants were more likely to incorrectly choose a face if the backgrounds were not all the same, regardless of the race of faces. Real-world implications from these findings are that using lineups where the backgrounds are slightly different hues may increase the likelihood of the false identification of innocent suspects.

摘要

当前的研究调查了列队辨认成员之间背景颜色的细微差异是否会影响对同种族和其他种族面孔的识别准确性。采用成熟的十分之一范式,一半的阵列面孔背景完全相同,另一半则处于色调略有不同的绿色背景上。对于有目标面孔的阵列,当所有背景都相同时,参与者识别同种族面孔的准确率高于识别其他种族面孔。然而,当背景色调略有不同时,人们识别这两个种族面孔的准确率没有差异。对于无目标面孔的阵列,无论面孔的种族如何,如果背景不完全相同,参与者更有可能错误地选择一张面孔。这些发现的现实意义在于,使用背景色调略有不同的列队辨认可能会增加错误识别无辜嫌疑人的可能性。
