I need to send the trigger according to the response the person gives. The responses are collected using keyboard component of the builder. The 8 allowed keys are from ‘f1’ to ‘f8’. The triggers that I send are very strange and every time different even if participant presses the same response button.
I use different version of the code with the simplest idea, but it does not work:
#this sends the first trigger that is taken from the excel file, and it works fine
#the second trigger should be sent 8 seconds later, and it should consist of the concatenation of the stimulus #type and the response given by the participant
x=key_resp_run1.keys #this should catch what response the participant chose, from f1 to f8
y=stimul_type #this is taken from the excel file
z=str(y)+str(x) #this concatenates the stimulus type and the response, for example,
#if the stimulus type is “4” and the response of the participant is “f5”, I want the trigger 4f5
the triggers which are sent are sometimes 2-digit, sometimes 3-digit, and even if the same stimulus type and response are pressed, the triggers that are sent are different.
I guess, the problem is in the line
x=key_resp_run1.keys #key_resp_run1 is the name of the keyboard component
