Dear all,
OS: Mac OS 10.15.7
PsychoPy version: v2021.2.3
Standard Standalone? yes
What are you trying to achieve?:
I am trying to build an experiment whereas the participants will receive instructions in different time points based on the subgroup that they belong to. More specifically, the subgroup A will receive general and specific instructions right after the “welcome message” and the subgroup B will receive general instructions after the “welcome message” and specific instructions after some time in “condition 1”.
What did you try to make it work?:
-
I have added to the Info Dialog the variable “subgroup” and I add the letters A or B accordingly.
-
This is my Builder with the Components related in red square:
-
I have added a Code Component in the “general_instructions” Routine:
Including the following code in the “Begin Experiment”:
if expInfo['subgroup'] == "A" :
instructionsspecloopnreps = 1
instructionsspecloopnrepsb = 0
elif expInfo['subgroup'] == "B" :
instructionsspecloopnreps = 0
instructionsspecloopnrepsb = 1
-
The content of the “instructions_spec_loop” is:
loopType: random
Is trials: unchecked
nReps: instructionsspecloopnreps -
Regarding “condition1”, I have added the following code in a Code Component:
if money_1 == 'add50_euro1' :
totalamount_con1 = 2250 + 50
msgfeedb_con1 = "You earned 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(2300)
totalAmount2.append(2300)
if expInfo['subgroup'] == "A" :# This relates with my problem
instructionsspecloopnrepsb = 0 # This relates with my problem
elif expInfo['subgroup'] == "B" : # This relates with my problem
instructionsspecloopnrepsb = 0 # This relates with my problem
elif money_1 == 'rem50_euro1' :
totalamount_con1 = 2300 - 50
msgfeedb_con1 = "You lost 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(- 50)
totalAmount2.append(- 50)
elif money_1 == 'add50_euro2' :
totalamount_con1 = 2250 + 50
msgfeedb_con1 = "You earned 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(+ 50)
totalAmount2.append(+ 50)
elif money_1 == 'rem50_euro2' :
totalamount_con1 = 2300 - 50
msgfeedb_con1 = "You lost 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(- 50)
totalAmount2.append(- 50)
elif money_1 == 'rem50_euro3' :
totalamount_con1 = 2250 - 50
msgfeedb_con1 = "You lost 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(- 50)
totalAmount2.append(- 50)
elif money_1 == 'add50_euro3' :
totalamount_con1 = 2200 + 50
msgfeedb_con1 = "You earned 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(+ 50)
totalAmount2.append(+ 50)
elif money_1 == 'rem50_euro4' :
totalamount_con1 = 2250 - 50
msgfeedb_con1 = "You lost 50 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(- 50)
totalAmount2.append(- 50)
if expInfo['subgroup'] == "B" : # This relates with my problem because I want after 7 times in condition1 the participants in subgroup B (and only them) to be presented with the specific instructions
instructionsspecloopnrepsb = 1 # This relates with my problem
elif money_1 == 'rem100_euro1' :
totalamount_con1 = 2200 - 100
msgfeedb_con1 = "You lost 100 euro. The amount of money that you have now is {} euro.".format(totalamount_con1)
totalAmount.append(- 100)
totalAmount2.append(- 100)
instructionsspecloopnrepsb = 0 # This relates with my problem
- The content of the “condition1_instructionsspec_loop” is (as seen in red square):
loopType: random
Is trials: unchecked
nReps: instructionsspecloopnrepsb
What specifically went wrong when you tried that?:
The problem is that sometimes the experiment works as I want by presenting the instructions for subgroup A and subgroup B in correct order and other times, without any intervention by me, the experiment stops after the “general_instructions” Component and I receive this message:

Thank you very much for your attention and your time,
Pauline
. Unfortunately I have added “instructionsspecloopnreps = 0” in a " Begin Experiment" code tab, but the problem remains the same. Thank you very much for your response and you time.
