Social scientists characterize social life as a hierarchy of environments, from the micro level of an individual's knowledge and perceptions to the macro level of large-scale social networks.

Thi...

Child-child similarity on attachment and temperament were examined, in turn, as predictors of interaction quality between previously unacquainted children. At 33 months, child-mother attachment security was assessed, and parents reported on child temperament. At 39 months, 114 children were randomly paired into 57 same-sex dyads and observed during 3 laboratory visits over a 1-month period. Pos...

Social networks support efficient decentralized search: people can collectively construct short paths to a specified target in the network. Rank-based friendship—where the probability that person u befriends person v is inversely proportional to the number of people who are closer to u than v is—is an empirically validated model of acquaintanceship that provably results in efficient decentraliz...

As a mixed-method study, this study investigated EFL test-takers’ perceptions of paired speaking tests and the role of interlocutor variables (i.e., peer interlocutor’s acquaintanceship, gender, and proficiency level) in pairing in a Cambridge English Language Assessment Open Center.

Across several choice domains—cars, dates, and hotels—we show that different attribute part...
