Hi Dave,
I have two questions that I need your help.
My experiment has 4 conditions and I want to randomly assign one condition to each participant (so each participant should only complete one of the four conditions).
Right now my script looks like this:
*******************************************************************************************************************
*******************************************************************************************************************
EXPERIMENT
*******************************************************************************************************************
*******************************************************************************************************************
<expt conditionCOG9>
/subjects = (1 of 4)
/groupassignment = random
/ blocks = [
1 = cogcondition;
2 = StartInfo;
3 = Practice_EmotionalStroop;
4 = EmotionalStroopcog9;
5 = panasfinal;
6 = vamsfinal;]
/ postinstructions = (end)
/onexptend = [
values.completed = 1;
]
</expt>
<expt conditionCOG2>
/subjects = (2 of 4)
/groupassignment = random
/ blocks = [
1 = cogcondition;
2 = StartInfo;
3 = Practice_EmotionalStroop;
4 = EmotionalStroopcog2;
5 = panasfinal;
6 = vamsfinal;]
/ postinstructions = (end)
/onexptend = [
values.completed = 1;
]
</expt>
<expt conditionsup9>
/subjects = (3 of 4)
/groupassignment = random
/ blocks = [
1 = supcondition;
2 = StartInfo;
3 = Practice_EmotionalStroop;
4 = EmotionalStroopcog9;
5 = panasfinal;
6 = vamsfinal;]
/ postinstructions = (end)
/onexptend = [
values.completed = 1;
]
</expt>
<expt conditionsup2>
/subjects = (4 of 4)
/groupassignment = random
/ blocks = [
1 = supcondition;
2 = StartInfo;
3 = Practice_EmotionalStroop;
4 = EmotionalStroopcog2;
5 = panasfinal;
6 = vamsfinal;]
/ postinstructions = (end)
/onexptend = [
values.completed = 1;
]
</expt>
*******************************************************************************************************************
End of File
*******************************************************************************************************************
And my current setting for Subject IDs is “User entered” and I will be asking for an email address.
My questions are:
1. does my script look like it is doing what I want to achieve? (randomly assigning each participant to one of four conditions)
2. do I have to change the current setting for subjects IDs for my study to run smoothly? (e.g., change it to “Random selection without replacement” and enter 4 for the section where it asks for “enter the total number of groups.” like the picture I am inserting here
As always, thank you for your help!!
