This communication collects the results from a survey on how a number of urban functional and symbolic interventions get integrated in the cognitive schemes, in districts in the city of Barcelona lacking these kinds of elements. We evaluate how these interventions also affect the identification and social life of their inhabitants. A survey has been carried out on a sample of three hundred and forty individuals by means of a questionaire. The results show that the contributions have had an important incidence in the cognative schemes of the citizens, although they do not reach an identification with the district. By now they are, however, integrated in the individuals the way of the look the city is inteded to show.
