Here are some of the questions I am working on with regard to
Since I am really focusing, at present, on the fovea, I am
interested in what is really picked up in a fixation. This is related
to the idea of the old span of apprension ideas. Most objects are
larger than the fovea and since the periphery seems to be involved in other
aspects of vision than object recognition (Leibowitz,
Rodemer, & Dichgans, 1979) then it is important to know what exactly
is picked up from an object in this brier image.
There are several subquestions here:
What is seen in a brief presentations. On way to look at
this is what is not missed when subtracted from an object.
How is integration across fixation accomplished.
This is a toughie. However, Krantz
(1988) found that extraocular signals recoordinate our visual axes
relative to the world slighly before a saccadic eye movement begins and
is finished just after it ends. This fact should help the brain
accomplish this fact.
What does the output from eye look like. If we apply
current models of receptive fields to an image and look at the output in a
graphical format, what would we see?
Here I have a list of questions
that seem beyond the current effort but I hope to engage down the road.
You might think of these as long range questions. I also have some
speculations related to these questions that suggest some possible avenues
