How do we know that people are part of a family? Findings from a  new study published in the <em>Journal of Vision<\/em> increases our understanding of the brain\u00e2\u20ac\u2122s ability to see through these underlying variations in facial structure.<\/p>\n<p>\u00e2\u20ac\u0153Being able to see the family resemblance between faces that have  some underlying difference, such as the difference between male and  female faces, is an ability that is not well understood and merits  further investigation to work out how visual information about faces is  organized,\u00e2\u20ac\u009d says author Harry J. Griffin, PhD, of the Department of  Cognitive, Perceptual and Brain Sciences at University College London.<\/p>\n<p>As described in the paper, (Relative faces: Encoding of family resemblance relative to gender means in face space),  researchers conducted two experiments using original and synthesized  cross-gender \u00e2\u20ac\u0153sibling\u00e2\u20ac\u009d faces that resemble each other and \u00e2\u20ac\u0153anti-sibling\u00e2\u20ac\u009d  faces that have the opposite characteristics of the original face.<\/p>\n<p>In the first experiment, participants were asked to identify  male-female sibling pairs. Possible pairings included a face with its  synthesised opposite-gender sibling, a face with its opposite-gender  anti-sibling, and a face with a randomly selected opposite-gender face.  Participants chose the sibling pair significantly more often than the  randomly selected cross-gender pairings and the random pairings more  often than the anti-face pairings.<\/p>\n<p>\u00e2\u20ac\u0153This pattern of results shows that<strong> when we see a face, we compare it  to an average face for that gender, allowing us to pick out only the  face cues that tell us about family membership while disregarding the  irrelevant gender cues<\/strong>,\u00e2\u20ac\u009d explains Griffin.<\/p>\n<p>In the second experiment, using the visual adaptation method of  biasing an observer\u00e2\u20ac\u2122s perception of objects through prolonged exposure,  participants were shown a male anti-sibling generated from a female  face. The results indicate that adapting to the male face clearly  influenced the perceived identity of a subsequent identity-ambiguous  female face. According to the researchers, this implies that the cues  underlying family resemblance for both male and female faces are  processed within the same brain space.<\/p>\n<p>\u00e2\u20ac\u0153We used this simple, non-invasive method to show that <strong>the facial  appearance of men and women are processed by overlapping populations of  brain cells<\/strong>,\u00e2\u20ac\u009d says Griffin.  \u00e2\u20ac\u0153This takes our understanding beyond the  conceptual and gives a picture of how the brain actually works.\u00e2\u20ac\u009d<\/p>\n<p>The research team hopes their findings will prompt other researchers  to investigate the perception of similarity in other aspects of facial  appearance such as underlying differences in age or racial groups. They s  also suggest the results may have an impact on the computer science  industry.<\/p>\n<p>\u00e2\u20ac\u0153Understanding how we encode faces can inform computer scientists who  are building face recognition systems for security applications and  computer graphics teams building synthetic faces for applications in the  film and gaming industry and to enhance human computer interaction,\u00e2\u20ac\u009d  added computer scientist and team member Peter McOwan from Queen Mary,  University of London.<\/p><\/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 Association for Research in Vision and Opthalmology press release: Whether comparing a man and a woman or a parent and a baby, we can still see when two&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2011\/11\/new-research-sheds-light-on-how-we-see-family-resemblance-in-faces\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[18,41],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/126"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=126"}],"version-history":[{"count":3,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/126\/revisions"}],"predecessor-version":[{"id":128,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/126\/revisions\/128"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=126"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=126"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=126"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
