I am working in DirectRT and I am attempting to do RWG. While DirectRT does randomize the tasks, it does so in such a way that it repeats one line instead of randomizing the four and using each of those four only once (as we would like it to do).
For example:
---The Input---
Code:
block-trial-RBG-RWG-stim
1 1 0 1 triangle
1 2 0 1 ball
1 3 0 1 heart
1 4 0 1 star
---The Resulting Orders----
Code:
Test 1 Test 2 Test 3
-triangle -heart -star
-star -star -ball
-heart -ball -triangle
-triangle -star -triangle
Is there a way to randomize the trials such that the results would appear as:
Code:
Test 1 Test 2 Test 3, etc.
-triangle -heart -star
-heart -star -ball
-heart -ball -triangle
-ball -triangle -heart
so that each trial is randomized but only appears once in a test?
