Determining such communicative cues are significantly heritable means variation in this ability has a genetic basis, which led the researchers to the vasopressin receptor gene, known for its role in social bonding. <\/p>\n The study results, which are published in Scientific Reports, give researchers insight into the biology of disorders in which receptive joint attention is compromised, such as autism spectrum disorders (ASD), and may ultimately lead to new diagnosis and treatment strategies. <\/p>\n According to Yerkes researchers Larry Young, PhD, and Bill Hopkins, PhD, co-authors of the study, receptive joint attention is important for developing complex cognitive processes, including language and theory of mind, and poor joint attention abilities may be a core feature in children with or at risk of developing ASD. <\/p>\n Young is division chief of Behavioral Neuroscience and Psychiatric Disorders at Yerkes, director of the Center for Translational Social Neuroscience (CTSN) at Emory and William P. Timmie Professor in the Emory University School of Medicine Department of Psychiatry and Behavioral Sciences. Yerkes researcher Hopkins is also a core faculty member in the Neuroscience Institute of Georgia State University and newly named science director of the Iowa Primate Learning Sanctuary. <\/p>\n Young and Hopkins led a collaborative team of researchers from Yerkes, the CTSN, the Neuroscience Institute at Georgia State University and the University of Texas M.D. Anderson Cancer Center. They studied chimpanzees to determine the extent to which the animals follow gaze or pointing by a human. <\/p>\n \"We used chimpanzees in this behavioral study because their receptive joint attention abilities are well documented and their closeness to humans makes the study results the most likely to be generalizable to humans,\" says Hopkins. <\/p>\n Young's previous research in which he showed the vasopressin receptor gene was necessary for remembering individuals (or social memories) and for social bonding in male rodents was key to designing the current study. According to Young, variation in the length of a stretch of repetitive DNA, known as junk DNA, in the control region of the vasopressin receptor gene predicted if a male prairie vole was likely to form monogamous bonds with a mate. Human-based studies suggest that a similar repetitive element, referred to as RS3, in the control region of the human vasopressin receptor gene predicts romantic relationship quality and generosity. <\/p>\n <\/p>\n More: PUBLIC RELEASE DATE: 4-Feb-2014 Contact: Lisa Newbern lisa.newbern@emory.edu<\/a> 404-727-7709 Emory Health Sciences Following another's gaze or looking in the direction someone is pointing, two examples of receptive joint attention, is significantly heritable according to new study results from researchers at the Yerkes National Primate Research Center, Emory University.
