For example, your passport photo may look quite different from your driving licence, or your face in holiday photos. In fact, these differences can mean you look like a different person from one photo to the next, to those that don&#8217;t know you.<\/p>\n<div id=\"text\">\n<p>Research has shown <strong>when photos of an individual&#8217;s face are judged too dissimilar to go together, people will tend to think they show several different identities<\/strong>.<\/p>\n<p>Scientists from the University of Bristol tested this concept further by exploring what happens when the photos show faces with different expressions.<\/p>\n<p>Annabelle Redfern from the School of Experimental Psychology led this research which has been published in the journal\u00a0<em>i-Perception<\/em>.<\/p>\n<p>She said: &#8220;We created packs of 40 cards, each card showing a different face. The packs were either of neutral, un-expressive faces, or of highly expressive faces. We asked people to sort the packs into piles, so that there was a pile for each person.<\/p>\n<p>&#8220;Even though there were only two different faces in the packs, people tended to think there were many more &#8212; between five and eight on average.<\/p>\n<p>&#8220;But <strong>when the faces were expressive, people also made another type of mistake: they confused the identities<\/strong>, and were more likely to place photos of both faces together, as if they were of the same person.&#8221;<\/p>\n<p>This study shows that expressive faces can cause identity confusions, where photos of different people are thought to be of the same person.<\/p>\n<p>It also demonstrates that <strong>we don&#8217;t ignore, or factor out, expressions when we recognise someone from their face<\/strong>.<\/p>\n<p>Annabelle added: &#8220;The next stage in this research, following up on this study, is to explore what happens when we increase the familiarity of a face.<\/p>\n<p>&#8220;As we start to learn a face, and how it expresses itself, then we find that expressions stop hindering the recognition process.<\/p>\n<p>&#8220;This makes a lot of sense, if you think about your own experience with faces; if you know someone, you will recognise their face, irrespective of what expression it has.&#8221;<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the\u00a0University of Bristol press release: Photos of the same person can look substantially different.
