This script implements Millisecond'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_training.iqjs 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.

COGDRAS runs 8 cognitive tests in the following order:
1. Immediate Word Recognition Test (immediatewordrecognition_cogdras.iqjs) 2. Picture Presentation (picturepresentation_cogdras.iqjs) 3. Number Vigilance Test (numbervigilance_cogdras.iqjs) 4. Simple Reaction Time Test (simplereactiontime_cogdras.iqjs) 5. Choice Reaction Time Test (choicereactiontime_cogdras.iqjs) 6. Memory Scanning Test (memoryscanning_cogdras.iqjs) 7. Delayed Word Recognition Test (delayedwordrecognition_cogdras.iqjs) 8. Picture Recognition Test (picturerecognition_cogdras.iqjs)
Each test can be run within this batch script or as stand-alone tests. Each test takes approx. 2-3 minutes to run.
