Testing will be conducted in a laboratory setting at the University of Leeds. Subjects will be tested in small groups (5-10 maximum) in a large room. Each participant will be assigned at random to either the experimental or control group. Participants will be spaced out across the room and boards will be placed between participants to prevent them from seeing each other. Each participant will be sat in front of a computer and wear headphones. We have a dedicated computer laboratory that will accommodate this format of testing. The video will be projected on each individual computers and responses (identification decision and confidence judgments) will be collected through E-Prime computer software on a 3.20 GHz PC with a 17inch screen. Participants will be asked to write their face descriptions or their lists of capitals and countries on paper.
