The investigation of top-down effects on perception requires a rigorous definition of what qualifies as perceptual to begin with. Whereas Firestone & Scholl's (F&S's) phenomenological demarcation of perception from cognition appeals to intuition, we argue that the dividing line is best attained at the functional level. We exemplify how this approach facilitates scrutinizing putative interactions between judging and perceiving.
