Are events and affordances commensurate terms?

In this article, I argue that the dichotomy between events and affordances as Stoffregen (target article, this issue) devises is unwarranted and poten tially misleading. I challenge the notion that the role of the actor distin guishes events from affordances in any useful way. The research labeled eve nt perception is neither less ecological nor qualitatively different from r esearch on affordances. Instead, the main distinction is constituted by aff ordance being a perceptual property, whereas event pertains to a different semantic category. Nonetheless, the contemplation of these concepts, in par ticular an elaboration of the concept of affordance, is desperately needed.
