Researches in the Environmental Psychology consider interaction between man and the environment as the cause and the effect of modifications and adjustments involving perceptive and cognitive skills. In particular we want to make reference to the socio-cultural perspective and to Fenoglio’s ‘structure of opportunities’: the first paradigm considers man as a maker of sense and significance both in a social and in an individual perspective; the second paradigm considers the actions of man as functionally planned according to the physical and social characteristics of the environment. The object of our investigation is Mobility and it is analysed through: - a semiotic and communicative approach, according to which the individual actions take up symbolic meanings and they are considered as a form of social and cultural exchange; - an adaptation approach (locus of control), which is determined and influenced by the rules and ‘restrictions’ of mobility, the characteristics of roads and streets, and by the Highway Code. Mobility is a modern phenomenon involving crucial aspects of social interaction. On the one s ide it modifies the inter-individual and the intra-individual relations; on the other side it represents a priority in the political agenda due to its relevance for the whole community and to its effects on social life and interindividual relations. According to this point of view the ‘street’ becomes a social, cultural, intergenerational laboratory; a ‘Lewinian field’ where different forces originating from individual needs and self-interests conflict and where it is necessary to find a socially accepted way to turn them into responsible and shared behaviour. The research, carried out in Bergamo in 2006 and 2007, has also pointed out the relevance of an intergenerational approach which involves different points of view in both educational and repressive processes in order to facilitate an osmosis of social and cultural values. The experimental research has involved the University of Milan, the Municipality of Bergamo, the Metropolitan Police of Bergamo, some Nursery Schools and some Compulsory and Secondary Schools in Bergamo. The police officers are leading an educational programme with the supervision of a team of psychologists: they are testing some pedagogical kits on pupils and students but also on their families - in particular parents and grandparents - with the aim of modifying the attitudes and social values concerning driving behaviour.
