On revising assumptions

Michaels (2000) reviewed some basic assumptions in the ecological approach in the light of recent experimental findings. Other reviews have also recen tly appeared (e.g., Stoffregen, 2000; Stoffregen & Bardy, in press). Here, it is suggested that some assumptions underlying the ecological approach ar e actually restrictive. The consequences of relaxing them are discussed as well as the contribution that phenomenological methods might make.
