ABSTRACT
All systematic attempts to understand or explain human experience and be havior entail assumptions about the nature and importance o f people’s rela tionships with their environments. Often, these assumptions are hidden, and are not thoughtfully examined (cf. Slife &. Williams, 1995). In environ mental psychology, researchers and theorists have a special obligation to ex am in e an d re flec t on th eir un derly in g a ssu m p tio n s regard in g person-environment transactions, because such events are a core concern o f the field (cf. Craik, 1996).
