n-back/CRT - memory task

[Anne-Wil]

Hi Maayan,

You need a so-called 'user defined variable': open the script window and 
click on the 'user' tab (at the bottom). If you define a variable on that 
tab ('dim variable as...' ), the information held in that variable will be 
kept over trials (as opposed to variables in lists or defined within 
procedures, which are 'reset' at each run of a procedure).

Good luck!
