A schematic diagram illustrating the delayed match-to-sample memory task in Experiment 1. Note. Each trial begins with a 30-s study phase of a latent fingerprint impression (a). After the study phase, there is a 500-ms delay (b). Next, a sequence of 10 fully rolled fingerprint impressions is presented (c). One of these is the target stimulus, while the remaining nine are distractor stimuli. Following their selection, participants receive corrective feedback for 500 ms before proceeding to the next trial (d)
