Abstract
Introduction
Previous research reveals that two factors influence the perception of tiredness in a face: the height of the upper eyelid (pretarsal show, both increased and decreased), and increased eyebrow elevation. We aimed to design, develop and validate a set of stimuli to differentiate the characteristics that increase perception of a tired face.
Methods
A hand-drawn picture of a neutral face was modified using imaging software to create a series of ten images, varying in degrees of pretarsal show, upper/lower lid depression and elevation, and eyebrow shape and position. Participants (n=63) from the general population were presented with the images and asked to quantify on a scale of 0-10 the presence of eight emotions or states – “surprise”, “anger”, “tiredness”, “sadness”, “disgust”, “alertness”, “fear” and “happiness” with 0 being the lowest and 10 being the highest rating.
Results
One way repeated measures ANOVAs were conducted to determine, for each image, which emotions were rated significantly differently from each other. For the images with increased pretarsal show and upper lid depression, tiredness was rated significantly higher than other emotions (F[4.04,173.6]=33.67,p
