Stimuli depicted are examples of photographs taken of men who consented to have their images reproduced for scientific communication.
300 faces were briefly presented in a random sequence and participants made a binary attractiveness judgement about each one: attractive or not attractive.
Moreover, previous studies have used laboratory stimuli, controlling for low-level visual properties for the purposes of drawing inferences about the visual system.
We then analysed each subject’s sequence of attractiveness judgements, binning them into two groups based on whether a given face was preceded by an attractive or unattractive face.
Comparing these groups allowed us to test whether face attractiveness on the current trial [t] was contingent upon the previous [t − 1] trial’s face being attractive.

Horizontal dashed line indicates general attractiveness (mean attractiveness score for all faces averaged across all subjects).
