In reference to three theoretical models in social psychology: the theory of the "Self", the Social Representations theory, the intra-group and inter-group dynamics investigation, we analyse the difficult relations between the generations. Computer languages, one of the main obstacles to communication between generations, become a tool of the relationship between elderly and young people in researches/ experimentations of inter-generational vacation (Viterbo, 2000-2012) carried out by the Generational Meetings Laboratory of Milan’s University. The research data analysis shows that computer’s lab tasks and digital photography activities, historic trails and nature trails during the holyday, help the knowledge and the relationship between people of different generation, in overcoming stereotypes and prejudices. As during laboratory of informatics activities, during leisure as well, the research highlights the intergroup relations evolution that, from an approach phase it evolves towards the acquaintance among the attendants, up to generate moments of real empathy. The researches/experimentationsenable institutional networks in the host territory: "To socialize the generations, by socializing the institutions".
