A Reply to Fodor and Phylshyn - Part 2

Continuing the reply that I think should have been made to Fodor and Pylyshyn's 1981 attack on Ecological Psychology. In F&P's article, the key elements of which are summarized here. They assert a very traditional, dualistic view of perception - as a process requiring sensory information to be supplemented by other cognitive processes in order to create an representational mental model of the world. They then point out (rightly) that some of Gibson's insights can be integrated into the traditional view and further assert (wrongly) that Gibson is thus offering nothing new. In so doing, I want to avoid as much as possible taking any bait offered by F&P which risk reeling us into to covert dualistic assumptions. I suggest that the best way to avoid such missteps is to stay firmly rooted in the line of thinking descended from pragmatism. Part 1 of my reply covered the meaning of "perception", "specification", and "direct perception", and the importance of remembering that if two things have all the same consequences, then they are the same thing (one crucial way of avoiding false distinctions). In this part I will continue to explain Gibson's approach by elucidating problems in F&P's critique.

Specification and Perception - Fodor and Pylyshyn (1981)

After doing a mediocre job suggesting a that Gibson's needs to be defended from within the Pragmatism-lineage (as opposed to, say Descartes's lineage or Kant's), something more blunt and obvious might be in order. I have argued that much confusion was created in the past debates over ecological psychology because its critics were not treating it as part of the pragmatic lineage, and its defenders met the attack on the critics’ terms. This lead, I think, to the defenders formalizing ecological psychology in a way that loses some of the unique potential of the approach. The trouble seems to have originated, largely, in the 1981 criticism by Fodor and Pylyshyn, which was replied to in the same year by Turvey, Shaw, and Mace. While the resulting "TSM" model of ecological psychology has led to much success, I won't deny that for a minute, I think that much of the current confusion within the field of ecological psychology traces back to this exchange. Below I will go back through Fodor and Pylyshyn's paper, to point out where I think they unfairly set out their challenge, i.e., where they tried to judge ecological psychology based on premises the pragmatic tradition rejects. In the next post, I will sketch what I think the reply to Fodor and Pylyshyn should have been. In a later post, I will go through Turvey, Shaw, and Mace's paper, to show how the acceptance of Fodor and Pylyshyn's premises lead them to conclusions at the heart of current debates in the field.

Two Ecological Psychologies - Continued

Continuing on my attempt to update Cutting's 1982 paper... two questions seemed of the most interest to blog readers 1) Why did Cutting write the original article? 2) What consequences of following Gibson's approach vs. the Connecticut approach?

WHY DID CUTTING WRITE IT?

The first question is more difficult. A lot was going on in the field at the time. All I can say for sure is that Cutting thought that Ecological Psychology was being moved away from Gibson's vision, and he thought that some aspects of the emerging approach were problematic (either because they undid desirable novelty of Gibson's approach, or because they resulted in tautology and related logical problems). It is worth noting, however, that regarding most of the differences, Cutting did not claim either approach was superior, only that they were different. He thought these differences would lead, presumably in the near future, to a splintering of the field. While I think most of Cutting's insights about the two emerging approaches were spot on, it has been thirty years, and the field is still together. Explaining why Cutting was wrong in that final prediction requires that we answer reader's second question.
