Big malls with multiple commercial and entertainment activities, concentrated in one place, originated in North American cities, rapidly expanding to the rest of the world. These kinds of spaces, typical of the metropolis, concentrate in a single space a wide diversity of facilities, which would otherwise be spread throughout the city. Malls have not been left outside people-environment studies. Therefore we can find research on wayfinding, orientation and architectural legibility (Ufuk & Feyzan, 2000; Yoo, 1992), among others. The malls offer multiple activities concentrated into a limited time frame, in order to motivate frequent visits promoting habitual patterns of mall attendance. Thus, malls become new reference places for users in the same way that residential and dwelling places and neighborhoods as well as working places, are reference places. This view of the mall raises the need for the studying of these places, approaching psychological processes such as appropriation of space, place identity and place attachment, in order to know the variables and their possible relationships in each one of them. Such studies could facilitate architectural conception and design of the malls. As Hidalgo (1998) has indicated, there are few places apart from communal ones in which studies have been made about attachment, besides those mentioned by Altman & Low (1992). Services that traditionally were offered in the neighborhood (Amérigo, 2000) have been transferred to the mall, even though the neighborhood keeps on being where place attachment generally happens. Malls generate an artificial environment which offers the possibility of new social relationships and for this reason these sociophysical spaces may become objects of place attachment.
