Persistence of social signatures in human communication (2012, background): “These were collected during a study (19) that tracked changes in the ego networks of 24 students over 18 mo as they made the transition from school to university or work (details in Materials and Methods).”
Associations among relational values, support, health, and well‐being across the adult lifespan (2017, background): “Indeed, Walen and Lachman (2000) suggest that friendship networks may exert a larger influence on health in late life not only because they are selective relationships (Roberts & Dunbar, 2011) but also because friendships may often be the only relationships left in an individual’s life.”
Do online social media cut through the constraints that limit the size of offline social networks? (2016, background): “This limit is thought to arise from a combination of a cognitive constraint (the product of the relationship with neocortex size known as the social brain hypothesis (SBH) [18,23]) and a time constraint associated with the costs of servicing relationships [24,25].”
How many hours does it take to make a friend? (2019, background): “The size of the next two groups follows the rule of three (40–50 friends; 120–150 clansmen) (Dunbar, 1996; Miritello et al., 2013; Roberts & Dunbar, 2011).”
The structure of online social networks mirrors those in the offline world (2015, methodology): “In humans, self-rated estimates of the emotional closeness for dyadic relationships (using a simple 0–10 analogue scale) correlate closely with the frequency of contact (Roberts and Dunbar, 2011; Arnaboldi et al., 2013a), and these in turn correlate with willingness to behave altruistically towards ”
