Das Projekt "Ortsveraenderungen als Gelegenheit zur Aenderung des Selbst" wird vom Umweltbundesamt gefördert und von Universität Heidelberg, Psychologisches Institut durchgeführt. An ecological approach to stability and change in the self-concept is presented. The self-concept develops and changes in an ecology consisting of objects, others and environments which serve as reflections, symbols, and conditions for self-relevant activities and interactions. It is stable as long as this ecology is stable. For instance, the network of others is stabilized through social commitment to a central role that also difines other relationships. Social commitments are entered or left on the basis of an evaluation by oneself and by a significant other, questioning or reinforcing the existing self-concept. Differential patterns of adjustment were found on self-relevant behaviours. Current research studies the restructuring of the ecology of the self after relocation. Methods for assessment of the ecology of the self were developed.
