Human social interactions ensure recognition and approval from others, both in offline and online environments. This study applies a model from behavioural genetics on Instagram sociability to explore the impact of individual development on the behaviour on social networks.We hypothesize that sociable attitudes on Instagram resulted from an interaction between serotonin transporter gene alleles and the individual’s social relationship with caregivers. We assess environmental and genetic components of 57 Instagram users. The self-report questionnaire Parental Bonding Instrument is adopted to determine the quality of parental bonding. The number of posts, followed users (“followings”), and followers are collected from Instagram as measures of online social activity. Additionally, the ratio between the number of followers and followings (“Social Desirability Index”) was calculated to estimate the asymmetry of each user’s social network. Finally, buccal mucosa cell samples were acquired, and the polymorphism rs25531 (T/T homozygotes vs C-carriers) within the serotonin transporter gene was examined.In the preliminary analysis, we identified a gender effect on the number of followings. In line with our predictions, we specifically found a gene- environment interaction on the standardized Instagram “Social Desirability Index”: users with the genotype more sensitive to environmental influences (T/T homozygotes) showed a higher Instagram “Social Desirability Index” than non-sensitive ones (C-carriers) when they experienced positive maternal care.This result may contribute to the understanding of online social behaviour from a gene*environment perspective.
