Fig 1.
An example trial in which the passport photo contains 50% of the target identity (left) and 50% of the fraudster’s image (right, embedded in the passport frame). The individuals shown in Fig 1 have given written informed consent (as outlined in PLOS consent form) to publish these images.
Fig 2.
Morph levels used in passport frames for Experiments 1 and 2.
The individuals shown in Fig 2 have given written informed consent (as outlined in PLOS consent form) to publish these images.
Fig 3.
Mean passport image acceptance rates across morph levels for Experiment 1.
(Error bars denote standard error.)
Fig 4.
Mean response rates across morph levels for Experiment 2.
Fig 5.
Face matching plotted against proportion of 50/50 morphs detected (some points over-lay).
Fig 6.
Morph levels between a participant and a foil face from the GFMT.
The individuals shown in Fig 6 have given written informed consent (as outlined in PLOS consent form) to publish these images.
Fig 7.
Mean acceptance rates across morph levels for Experiment 3.
(Error bars denote standard deviation).
