Abstract：
Oxytocin is a primary neuropeptide which coordinates affiliative behavior. Previous researchers pointed to the association between genetic vulnerability on Oxytocin Receptor Gene (OXTR) and environmental factors (e.g., social relationships) to comprehend social behavior. Although an extensive knowledge of in-person social interactions has been obtained, little is known about online sociability. A gene-environment perspective is adopted to examine how OXTR and adult attachment moderate Instagram behavior. The genetic factors within the regions OXTR/rs53576 (A/A homozygotes vs G-carriers) and OXTR/rs2254298 (G/G homozygotes vs A-carriers) were assessed. The Experience in Close Relationships-Revised (ECR-R) questionnaire was used to collect participants\' (N = 57, 16 males) attachment with a partner. The number of posts, followed people (\"followings\") and followers were obtained from Instagram, and the Social Desirability Index (SDI) was calculated as the ratio of followers to followings. Interaction effects between OXTR groups and ECR-R scores on the number of posts and SDI were hypothesized. Results showed an effect of rs53576 on the number of Instagram followings. Specifically, people with A/A OXTR/rs53576 genotype had more followings than G-carriers independent of the anxiety or avoidance felt towards their partner. These preliminary results offer insights into future investigations on social media behavior.
摘要：
催产素是协调亲属关系行为的主要神经肽。以前的研究人员指出催产素受体基因(OXTR)的遗传脆弱性与环境因素(例如，社会关系)来理解社会行为。尽管已经获得了关于面对面社交互动的广泛知识，人们对网络社交能力知之甚少。采用基因环境视角来研究OXTR和成人依恋如何调节Instagram行为。评估了OXTR/rs53576（A/A纯合子vsG携带者）和OXTR/rs2254298（G/G纯合子vsA携带者）区域内的遗传因素。亲密关系经验修订（ECR-R）问卷用于收集参与者（N=57，16名男性）与伴侣的依恋关系。帖子的数量，跟随人(“追随者”)和追随者是从Instagram获得的，社会期望指数(SDI)计算为追随者与追随者的比率。假设OXTR组和ECR-R分数对帖子数量和SDI的交互作用。结果显示rs53576对Instagram关注次数的影响。具体来说,A/AOXTR/rs53576基因型患者的随访次数多于G携带者,而与对伴侣的焦虑或回避无关.这些初步结果为未来对社交媒体行为的调查提供了见解。
