Hi Dave,
I've checked the Inquisit Language Reference, but can't seem to find much information or examples on using the noreplace and noreplacenorepeat functions.
So, I have three main questions:
1. In the following script, if using noreplace, will that mean each of the three trials is run through randomly four times?
2. If I use noreplacenorepeat instead of noreplace, will that mean each of the three trials is run through randomly four times, but the only change is that a given trial will not run directly after itself (e.g., there will be no trial_a followed directly by another trial_a). Does noreplacenorepeat have any other effect?
3. Does the script run through the items in each trial in sequential order, or are they run in random order? (e.g., For trial_a, will the items run through sequentially as /1 = "A", /2 = "B", /3 = "C"). Does using noreplace or noreplacenorepeat affect the order in which the items within a trial are run? Is it possible that a given item will ever be run directly after itself (e.g., /1 = "A" followed directly by another /1 = "A" which this trial_a is run)?

Thanks in advance!
