Figure 1. Representative Emotion Match and Shape Match trials.
Target items are at the top of each display, and choice items at the bottom. In the Emotion Match trial (left panel), the target face and the choice face on the right both express fear, and are therefore a correct match. The choice face on the left expresses anger, and is therefore an incorrect match. In the Shape Match trial (right panel), the correct choice is the item on the right, as it corresponds in shape to the target item.
