It will be possible to find studies with same problematic, the referring one to one same context, however with different metodolgica boarding and this, being determined for the professional and/or demand of the context, reflecting the wealth of the object of disciplines (EVANS, 2005). Although each professional to have its way to see the world, to follow one definitive theory and methodology, in accordance with its personal and/or professional interests, all study in ambient psychology will exclusively be come back toward the relation person-environment, and Wiesenfeld (2005, p.55) classifies as objective of this disciplines: To study the relation person-environment in the natural context, sight as totality (ontologia), to approach the said relation in holistic way (methodology), to incorporate diverse theoretical perspectives in its study (epistemologia), to emphasize the social dimension of the ambient human relation, to establish bonds with others you discipline interested in the thematic ambient human being (interdisciplinaridade), to apply the gotten knowledge to improve ambient quality e, therefore, the quality of life of the users of environments (social relevancy). Seen the multiplicity metodolgica to study the interaction man-environment, one becomes necessary to define methods for collection of data and techniques that will be used, giving an emphasis for the knowledge previous of the thematic one, available quantification of the time and resources. according to Gunther, Elali and Pinheiro (2004, p.3) ' ' the way most common to deal with the multiple boardings, theories and methods in an area as of the EPA is make reference to reference the necessity of an Inter treatment, multi- and/or to transdisciplinar (IMT) of the subjects for it trabalhados' '. Fedrizzi and Tomasini (2008, P. 320-321) define below these terms sufficiently used in ambient psychology: Multidisciplinaridade: it configures a situation where diverse you discipline if they involve, however, without the occurrence of its respective interactions; Interdisciplinaridade: here, the interactions and the coordination if define for the nature of the complexity of the problem in question; Transdisciplinaridade: finally, in this in case that, the interactions do not only become enter discipline, but also between the different involved social actors, are they, the local planners, administrators and populations.
