"Although Barker theoretically conceptualized discrepancies between the "program" of the setting and events actually happening, he was primarily interested in states of "congruence" or "fit". Theoretical considerations and results of empirical studies are presented which focus on intra- and interpersonal processes resulting from events evaluated as contradicting to programs of settings. The results and their interpretation indicate that (a) Barker's approach generally offers room for this kind of events (b) criticisms concerning the static and a-psychological character of his concept may be taken up productively (c) for this, a crossfertilization of ecological with socialpsychological concepts is inevitable."
