The unprecedented growth of social network users in the last decade has resulted significant increases availability individual-specific information such as holiday pictures, mobile check-ins at restaurants, and on everyday purchases. Consumers shopping through channels are increasingly using this making their purchase decisions. We find that ties impact magnitude observational learning. In case...

'Infant shyness', in which infants react shyly to adult strangers, presents during the third quarter of the first year. Researchers claim that shy children over the age of three years are experiencing approach-avoidance conflicts. Counter-intuitively, shy children do not avoid the eyes when scanning faces; rather, they spend more time looking at the eye region than non-shy children do. It is cu...

In many cooperatively breeding birds and mammals, group size is positively correlated with reproductive success. In marmoset and tamarin monkeys, species that display cooperative breeding, the presence of helpers appears to be critical for offspring survival, and breeders might be expected to display social strategies that would regulate group size. This study investigated the association betwe...

In this work, we examine familiar strangers on Blogosphere and issues of finding them. In our daily life, familiar strangers, as coined by Stanley Milgram, do not know each other, but frequently exhibit some common patterns. Blogosphere is a part of the Web where bloggers post in individual or community blog sites. The nature of the Web is a scale-free network, which determines that a power law...

Adversaries leverage social network friend relationships to collect sensitive data from users and target them with abuse that includes fake news, cyberbullying, malware, and propaganda. Case in point, 71 out of 80 user study participants had at least 1 Facebook friend with whom they never interact, either in Facebook or in real life, or whom they believe is likely to abuse their posted photos o...

In this research we explore anonymous, one-shot exchanges among “neighbors” and among “strangers” in four countries. Specifically, we compare levels of trust and reciprocity in a direct-reciprocal (dyadic) exchange, with those in network generalized exchanges among experimentally manipulated groups’ members (neighbors) or random experimental participants (strangers). We demonstrate that levels ...

Social interactions among individuals are wide-spread, both in natural and domestic populations. As a result, trait values of individuals may be affected by genes in other individuals, a phenomenon known as Indirect Genetic Effects (IGEs). IGEs can be estimated using linear mixed models. The traditional IGE-model assumes that an individual interacts equally with all its partners, whether kin or...

Even before COVID-19, it was well known in psychological science that people’s well-being is strongly served by the quality of their close relationships. But also social contact with people who are less well? In this article, we discuss three propositions support conclusion benefits derive from interactions acquaintances and even strangers.
