Observers were presented with images selected from the popular fantasy game Dungeons and Dragons (D&D; figure 1a). The images could be of humans, creatures with eyes in the centre of the face (humanoids), and creatures with eyes that are not on the face but broadly distributed on other parts of the bodies, such as the hands or the tail (monsters). The question is straightforward: will there be a preferential bias to select the eyes of monsters despite the fact that their eyes are not in the centre of their face? —Biology Letters
Study used D & D characters to test how subjects responded to eyegaze in human, humanoid, and monster characters.
