| description | We report three experiments that test the limits of the Mona Lisa effect. The
gaze of a portrait that is looking at us appears to follow us around as we
move with respect to the picture. Even if our position is shifted
considerably to the side, or if the picture is severely slanted, do we feel
the gaze to be directed at us? We determined the threshold where this effect
breaks down to be maximally 70° of picture slant relative to the observer.
Different factors modulate this remarkable robustness, among them being the
display medium and the nature of the picture. The threshold was considerably
lower when the picture was mounted on a physical surface as opposed to a
computer simulation of slant. Also, the more the portrayed object deviated
from the photograph of a human head, the less robust the Mona Lisa effect
became. Implications for theories of perspective distortion are discussed. |
