Figure 2.

Sample stimuli used in the present study. A sample target stimulus is shown in the “Identical” column. Sim3-Sim0 columns illustrate progressively less similarity with the target as more features, 1^st order relations, or 2^nd order relations are changed. For example, featural face changes were created by changing the lips of the target face (Sim3), the lips and nose (Sim2), the lips, nose and eyebrows (Sim1), or the lips, nose, eyebrows and eyes (Sim0). Although single stimuli are illustrated here, stimuli were presented in pairs so that the target and the sim3 stimulus form a sim3 pair.
