This commentary attempts to make two points: First, although Purves, Morgenstern, and Wojtach (PMW) are likely correct that the retinal image alone is an insufficient basis for successful visually guided action (Purves et al., 2015a, p. 1), their “vision as reflexive” strategy emphasizes the perceptual associations and neural portions of the visual system at the cost of understating the central role environmental information plays in vision. Second, although PMW are correct that early empirical strategies did not sufficiently incorporate neural aspects of the visual system (pp. 2–4), recent attempts to demonstrate how affordances relate to the nervous system help demonstrate that ecological psychology (EP, Gibson, 1966/1983, 1979/1986) remains a viable empirical framework for investigating and explaining vision.
