What have experimental studies revealed about our ability to recognise faces
There have been many experimental studies which have helped contribute to our knowledge of the ability of humans to recognise faces. There are many problems that occur when it comes to the ability to recognise faces especially when recognising a face from a picture or a camera still e. ... Studies carried out on the different ways in which face recollection can be affected will be referred to. ... The ability for a human to recognise face’s is believed to be relatively good, humans can usually identify familiar faces with no or little effort, despite lighting, viewpoint and expressions. However when it comes to recognition of unfamiliar faces there is a problem but this problem is more to do with picture recognition than face recognition and our ability to remember and match the faces. ... Lighting and Negation: A photographic negative is more difficult to recognise than an inverted image as a negative inverts the pattern of brightness across an image. ... The person will be able to obtain information about the size and position of facial features but that is about it. Inverted or negated familiar faces are easier to recognise if they have been bottom-lit indicating that Inversion has an effect on perception of shape as well as disrupting processing. ... Inversion removes the sensitivity which humans acquire when configuring upright faces. ... unusual faces are better remembered than typical ones. Studies have shown that faces rated as typical are more likely to give rise to a false positive recognition while distinct faces are better recognised on tests. ... However the error rate was still on average ~20%, with some faces giving rise to very high error rates. ... Mike Burton carries out an experiment on the effects of familiarity in which he examines the ability of a subject to recognise images from a security system depending on whether they are familiar with the target or not.
