By combining separate measures of recall and recognition, we show that people know about 5000 faces on average and that individual differences are large. Do our thoughts do something different with familiar and unfamiliar faces, we perceive facial expressions but where do they come from and what exactly do they mean? A collection of ten "1000 Faces " NFTs in various colours, each one is unique. Personally designed by the artist with lots of love, passion, effort & hard work.
