Abstract The objective of this study is twofold. First, it aims to investigate the various values users achieve with smartphones, which is a form of user‐empowering information technology (IT).

An important attraction of smartphones is their personalized environment, which is mainly provided by varied applications.

Despite an exponentially increasing number of registered users, social virtual worlds have the problem of a high user attrition rate.

This paper presents a methodology for socio-cognitive research based on the theory of social representations. Elements of the methodology include:1) data elicitation through free word association; 2) content analysis/coding to identify key concepts in the social representation; 3) analysis of the structure of the representation using analysis of similarity and core/periphery analysis; 4) correspondence analysis to place the concepts on a perceptual space; and 5) interpretation of the social repr

However,
