Impact of disguise on identification decisions and confidence with simultaneous and sequential lineups. Law and Human Behavior (IF3.795), Pub Date : 2020-12-01, DOI: 10.1037/lhb0000427 Jamal K Mansour,Jennifer L Beaudry,Michelle I Bertrand,Natalie Kalmet,Elisabeth I Melsom,Roderick C L Lindsay
Prior research indicates disguise negatively affects lineup identifications but the mechanisms by which disguise works have not been explored and different disguises have not been compared. We investigated how two different types of disguise, four levels of varying degrees of coverage, and lineup type influence eyewitnesses' identification decisions, accuracy, and confidence.
We predicted that identification accuracy would decrease as the disguise covered more of a perpetrator's face. We also predicted that type of disguise-stocking mask versus sunglasses and/or toque (i.e., knitted hat)-would influence identifications, but we had conflicting predictions about which disguise would impair their performance more.
In two experiments (Ns = 87 and 91) we manipulated degree of coverage by two different types of disguise: a stocking mask or sunglasses and toque. Participants viewed mock-crime videos followed by simultaneous or sequential lineups.
RESULTS AND CONCLUSIONS
Disguise and lineup type did not interact. In support of the view that disguise prevents encoding, identification accuracy generally decreased with degree of disguise. For the stocking disguise, however, full and 2/3 coverage led to approximately the same rate of correct identifications-which suggests that disrupting encoding of specific features may be as detrimental as disrupting a whole face. Accuracy was most affected by sunglasses and we discuss the role meta-cognitions may have played. Lineup selections decreased more slowly than accuracy as coverage by disguise increased, indicating witnesses are insensitive to the effect of encoding conditions on accuracy.
