INSTRUCTIONS
If you click on the MAKE A LESION button, one of the arrows or boxes is
randomly selected and no longer functions. Your mission is to discover
which box or arrow is lesioned by administering tests to the system and
seeing whether the system can still perform the test or fails on it.
To administer a test, click on the RUN A TEST button then click on a
test description in the scrollable list of tests. You'll get a message
at the bottom right hand corner of the window telling you whether the
damaged system succeeded or failed on this test.
When you think you know which box or arrow is the lesioned one, click
on the PROPOSE A LESION button, then click on the box or arrow that you
suspect is the lesioned one. The system will tell you whether you are
right or wrong.
If you are unsure what is involved in one of the tests, select DESCRIBE
A TEST from the ACTIONS menu, then click on the relevant test
name in the scrollable window.
If you are unsure what the function of a particular module (box) is,
select DESCRIBE A MODULE from the ACTIONS menu, then click on the
module you want to learn more about.
If you want to know, for any module or connection, which tests require
that this module or connection be intact for success on the test,
select WHICH TESTS DEPEND from the ACTIONS menu, and then click on the
module or connection you are interested in.
If, as you are proceeding with testing, you want to know what boxes and
arrows you have demonstrated to be intact so far, check the REVEAL
BOXES AND ARROWS box. Now whenever you administer a test that the
system succeeds on, the boxes and arrows that must be intact for
success on that test turn green.
If at any time you want to know what lesion was made, click on the SHOW
THE LESION button. The lesioned region of the model will turn red and
flash.
If you want to make the lesion yourself, when the MAKE A LESION button
is showing, click on a box or arrow to lesion it.
NOTE: Quite often there is no way of assessing whether it is a box that
is damaged or the arrow coming into it e.g. lesioning the
letter-to-sound rules box or lesioning the arrow coming in to it has
the same effect. Wherever this is the case, the set of boxes and arrows
which can't be discriminated are grouped together so that if one is
lesioned all are treated as having been lesioned.
We plan to update this system periodically in response to
comments/criticisms from users. These, plus bug reports, should be
sent to ssaunder@maccs.mq.edu.au
