Ecological psychology and experimental psychology appear as two different, unconnected worlds. Could they be reconciled or even integrated to one world? Ecological psychology claims to be responsible for all kinds of person-environment - interrelationships and may attempt to usurp experimental psychology by pronouncing all psychological experiments to be behavior settings. Supposing experimental psychology would not resist: would that have any consequences for it? Or would that amount to a Pyrrhic victory for ecological psychology? And how could experimental psychology enter into the realm of ecological psychology? What would be the repercussions on itself? The paper attempts to find at least some answers.
