Dear all, we just published a database of 500 Mooney face stimuli for visual perception research. Please find the paper here: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0200106 Each face was tested in a cohort of healthy adults for face detection difficulty and inversion effects. We also provide a comparison with Craig Mooney's original stimulus set. The stimuli and accompanying data are available from Figshare (https://figshare.com/account/articles/5783037) under a CC BY license. Please feel free to use them for your research. Caspar
