Abstract:
Human beings engage in multiple social interactions daily, both in person and online. There are, however, individual differences in the frequency and quality of these interactions. This exploratory study focuses on online interactions and aims to model these differences by looking at potential environmental and genetic factors. The environmental factor is the childhood parental relationship, as reported by the participants in the dimensions of the Parental Bonding Instrument (N = 57, 41 females). At a genetic level, buccal mucosa cell samples were collected to assess participants\' genetic susceptibility, and OXTr regions rs2254298 (G/G homozygotes vs. A-carriers) and rs53576 (A/A homozygotes vs. G-carriers) were analyzed. To capture participants\' online activity, Instagram was probed. The number of people that the individual follows (\"followings\"), followers, and posts were used as a proxy for the quantity of interaction, and a Social Desirability Index (SDI) was computed as the ratio of followers to followings. An interaction between OXTr groups and parental bonding scores on the number of followings and posts was hypothesized. A gene-environment interaction for OXTr/rs2254298 on the number of Instagram posts was identified. In line with the hypothesis, participants with a genetic risk factor (A-carriers) and a history of low paternal care showed fewer Instagram posts than those without this risk factor (G/G genotype). Moreover, an interaction effect between maternal overprotection and OXTr/rs2254298 on the Instagram SDI was detected. These findings could represent an indirect pathway through which genes and parental behavior interact to shape social interactions on Instagram.
摘要:
人类每天参与多种社会互动,无论是在人和网上。有,然而,这些相互作用的频率和质量的个体差异。这项探索性研究侧重于在线互动,旨在通过观察潜在的环境和遗传因素来模拟这些差异。环境因素是童年的父母关系,根据参与者在父母束缚文书维度中的报告(N=57,41名女性)。在基因层面,收集颊粘膜细胞样本以评估参与者的遗传易感性,和OXTr区域rs2254298(G/G纯合子与A-携带者)和rs53576(A/A纯合子与G-携带者)进行了分析。要捕获参与者\'在线活动,Instagram被调查。个人跟随的人数(“跟随”),追随者,帖子被用作交互数量的代理,社会期望指数(SDI)计算为追随者与追随者的比率。假设OXTr组和父母结合得分之间关于追随者和帖子数量的相互作用。确定了OXTr/rs2254298对Instagram帖子数量的基因-环境相互作用。根据假设,有遗传风险因素(A-携带者)和低父亲照护史的参与者的Instagram帖子少于没有该风险因素(G/G基因型)的参与者.此外,在InstagramSDI上检测到母亲过度保护和OXTr/rs2254298之间的相互作用作用。这些发现可能代表了一种间接途径,基因和父母行为通过这种途径相互作用来塑造Instagram上的社交互动。
