Hi all,I need to design experiment that has one quite complicated part...Imagine a chart which has 3 categories horizontaly, and 2 verticaly.It gives 6 places where you could put some informations (Graph 1)Graph 1 :) X | Y | Z$| 1 | 2 | 3&| A | B | C----------------In the chart there are text informations and they can be coded as a text stimuli as well as image - doesn't metter.
All information are definied (1,2,3 and A,B,C).Conections between numbers and letters are definied as well.
If 1 then AIf 2 then BIf 3 then C
I need to have those 3 boxes (horizontaly - X,Y,Z) randomly asign to information for each participant.
Inother words I'm looking for way to design random order for location foreach number inside those 3 boxes, and way to define from startconnection between numbers and letters in those boxes.
How to do it?
I have script where I have a static information, but I'm not sure where to start coding with this random order.Need to say one more thing. Each information is hidden under a red box during the experiment. Participants can use the mouse to see what's under those red boxes, however he can see only one information at once.
I don't have time to map this out in any detail, but I would use <counter> elements chained together with the 'current' function to encode the possible combinations of screen positions. This thread contains some more hints on this approach: http://www.millisecond.com/forums/Topic2148.aspx.
BTW, the 'current' option in '/select' might also be useful in the number to letter mapping (1->A, 2->B)...
