PsychoPy version : 3.2.4
What are you trying to achieve?:
I am doing the ultimatum game experiment, where the participant gets different monetary offer splits from the opponent and then has the option to either accept or reject the offers. After accepting or rejecting the offer, the participant should get a feedback message about the amount of money that they got or did not get.
If the offer is rejected, then the message should say that the participant received 0 cents. However, if the offer is accepted, then there are three possible messages saying that the participant either received 1, 3 or 5 cents (depending on the offer itself).
What did you try to make it work?:
So far I have created an excel folder that contains two possible variables “accept” and “reject”, where the corresponding texts to the monetary offers are written.
In Builder I then created two routines within the loop, one that should run if the right key button is pressed (accept_trial) and the other one if the left key button is pressed (reject_trial). In each of the routines I first created a text, referring to either $accept text in excel or $reject text in excel.
I also included one code to each routine, where resp_trial is the name of the variable for the keyboard response.
Example of the code for accepting the offer, written in Begin Routine:
if resp_trial.keys == 'right' : continueRoutine = True else: continueRoutine = False
Example of the code for rejecting the offer, written in Begin Routine:
if resp_trial.keys == 'left' : continueRoutine = True else: continueRoutine = False
What specifically went wrong when you tried that?:
The problem occurs with presenting the feedback message - always two feedback messages get presented, no matter whether the offer was accepted or rejected, instead of only showing the one relevant message. The first message therefore says, that the participant received 0 cents and the second one says that they received either 1, 3 or 5 cents.
