Smartphone use undermines enjoyment of face-to-face social interactions

Social network dynamics of face-to-face interactions

The recent availability of data describing social networks is changing our understanding of the "microscopic structure" of a social tie. A social tie indeed is an aggregated outcome of many social interactions such as face-to-face conversations or phone calls. Analysis of data on face-to-face interactions shows that such events, as many other human activities, are bursty, with very heterogeneou...

Analysing Face to Face Computer-mediated Interactions

Detailed analysis of face to face computer mediated interactions implies a study of a corpus composed of the interaction traces produced by the collaborative tool and video and audio recordings. Because of their separate nature, it is frequently difficult to perform this joint analysis. In order to facilitate such analyses we propose a model for describing corpora composed of sources from diffe...

Face to face with the social brain.

Recent comparative evidence suggests that anthropoid primates are the only vertebrates to exhibit a quantitative relationship between relative brain size and social group size. In this paper, I attempt to explain this pattern with regard to facial expressivity and social bonding. I hypothesize that facial motor control increases as a secondary consequence of neocortical expansion owing to corti...

Modeling face-to-face social interaction networks

On the complementary roles of face-to-face and mediated social interactions

Social interaction patterns have long been a subject of great interest. Several recent studies (e.g., [3, 2]) have examined the influence of face-to-face and mediated (e.g., phone, text and online social networks) communication channels on employees’ mood, but since their motivation stemmed from professional productivity, they did not include interactions that occurred outside the working envir...
