BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements Millisecond Software's version of the 
Cognitive Drug Research Computerized Assessment System (COGDRAS). 

The script runs 8 individual cognitive tests testing memory, attention and reaction times as a batch.
A final script collects all the relevant summary variables.

A starting script provides a brief overview of the testing session and practices the
response buttons. The default response buttons are:
Q = yes-key
P = no-key
(to change response buttons FOR THE ENTIRE batch go to section Editable Parameters in this script and
choose your response keys. Note that script ms_cogdras_start.iqx has to be edited to reflect the 
change) 

To change the order of the tests OR remove any of the tests from the batch go to section
EXPERIMENT and follow further instructions.
