Part of an email from Jayme to Steffen Werner, Oct 7, 2006
Changizi’s article started me thinking about Hubbard’s stimuli in his original RM in depth study where he used “approaching” and “receding” squares. When I went back to the original study I noticed that there was something wrong with stimuli measurements. I don’t know why but it kept nagging at me so I came home from work yesterday and started plotting out Hubbard's stimuli—and there is definitely something wonky between his probes and his inducing stimuli. Of course his sloppiness isn't what's interesting but rather that he seems to have inadvertently created two different temporal trajectories with the same, or nearly the same stimuli, so that there are different temporal depths.
And I remembered what you suggested in our meeting that we could set up an experiment with incongruities. I thought that was a great idea but I couldn't think of what to manipulate (and after 2 or 3 days of thinking I only came up with a couple of invertible word pairs). I began to wonder if there wasn't a way to exploit different temporal depths, which led me to start playing around with time/space plots (see below). If you keep time constant, at regularly spaced intervals, but vary the rate at which the object grows—imagine these are Hubbard's approaching squares seen from the side —then you get these different temporal depths. I used a rate of 1.10, 1.15, and 1.25 in these graphs—Hubbard used 1.5.
If you do the opposite and hold space constant, you get exactly the same depth.
Then I decided to invert the graphs and you get this weird visual similarity between space/time inverted and time/space inverted.
And you're probably wondering what on earth this has to do with our experiment and the answer is I'm not sure but I keep wondering if there isn't something useful in these relationships that we could exploit for incongruities.
In all of my ePortfolio work I talk about using the blog as an engine for collecting evidence and tagging that evidence so that during the selection process it is easy to filter. But I never follow my own advice. So as of today (1/15/13) I am going to begin dumping things in here and see if I can train myself to get in the habit of posting something at least once a week.
