title: Two visual streams: Interconnections do not imply duplication of function.
abstract: Abstract Schenk and McIntosh (S&M) provide a useful review of the perception-action model (PAM), highlighting some of the gaps that need to be filled, and counteracting the erroneous belief held by some that the PAM implies two mutually independent streams. Although we agree with S&M's contention that the functional independence of the two streams has been overestimated, we reject their speculation that "the specializations proposed may be relative rather than absolute." We argue that the contributions made by the two streams are quite distinct, and that establishing how they work together is the key to a full understanding of visually guided behavior.
