On sensation, perception and thought: A reply to Rönnberg

A traditional partition of cognitive phenomena into sensation, perception and thought is reintroduced in response to recent arguments (Rönnberg, 1990) for conditions that must be met in order to distinguish between perception and cognition. The suggested division seems grossly compatible with Ronnberg's basic aim and receives support from several different lines of inquiry, including single cell recordings in the brain, neurospsychology, computational studies of vision and experimental psychology.
