This was apparently a response to my message posted to the psyche-b discussion list. http://listserv.uh.edu/cgi-bin/wa?A2=ind0109&L=psyche-b&F=&S=&P=1199 This message announced availability of a free online version of my out of print 1978 book, The Computer Revolution in Philosophy at this URL http://www.cs.bham.ac.uk/research/cogaff/crp/ I also made some comments on vision to which he responded > Date: 30 Sep 2001 14:25:16 GMT > Organization: AOL http://www.aol.com > > >(...) because much of normal sight is "blind-sight" -- < > > If I were blind I'd not see at all. I was assuming that people reading the psycbe-b postings would be aware of research on "blind sight" in which people with certain kinds of brain damage claim not to be able see yet when asked to point at something do so successfully: i.e. they have a competence which usually goes with sight, but they lack the awareness of having sight, hence "blind-sight". There's a lot of literature on this, though I am not an expert. E.g. see http://cognet.mit.edu/MITECS/Entry/stoerig or Weiskrantz, L. (1986). Blindsight: A Case Study and Implications. Oxford: Oxford University Press. > When coming to normal sight, I might not regard the sequencer's or whatever as > being blind nor my own. > > My own just like MBD baud rate. I don't understand any of that. Sorry. You seem to be referring to a type of deficit that I do not recognize, and I don't know what sort of sequencer is being referred to. > Concerning some posture control due to something I heard I assumed that there > is some structure near the ear that is to do with that. There is a huge amount of published literature on this sort of thing. I was referring to the fact that there are experiments which show that we use optical flow in posture control even though we are not aware of the fact that there is any optical flow. Work on this was reported many years ago by David Lee at Edinburgh university. > I am not sure anymore > if there were several ring-like bones or something else and some fluid where > the position of that was relevant?

(And why do I even bother to ask English > vocabulary?) "affordance" is a technical term coined by the psychologist JJ Gibson in his theory of vision. It is well known to scientists who study vision. See J.J Gibson, The Ecological Approach to Visual Perception, Lawrence Earlbaum Associates, 1986, (originally published in 1979), I have the impression that you really are not interested in the work I reported though I cannot tell whether you have read it or are reacting only to the summary in the email message. Since most of your comments are not related to the work I was referring to, I guess I should let your points stand unopposed. We seem to be interested in different topics. I apologise if I wasted your time. Best wishes.
