[ Using Standalone PsychoPy on Windows 10. Builder View ]
I’m working on an experiment which requires to display a text character on screen during very short time gaps (20 frames each).
So I’m using a single text object, which gets the value of the character supposed to be displayed on a custom code, provided as follows:
[ Begin Routine section ]
txtset1 = ["A","B","C","D","E","F","G","H","I","J","K","L"] txtset2 = ["A","B","C","D","E","F","X","H","I","J","K","L"] txtrand = randint(1,10) if txtrand > 2: letras = txtset1 else: letras = txtset2
[ Each Frame section ]
aux = randint(0,len(letras)) chosen = letras[aux]
“Chosen” is the name of the variable set on the Text object, so it is the one being updated on each frame
The issue here, is that setting this “on each frame” is way too fast for this experiment. As said before, each character is expected to appear on screen during 20 frames. For example, during the first 20 frames any random character from the list should be displayed, then another random character during the next 20 frames and so on.
There is no option for setting the value for custom durations, so I thought of asking for help here.
A friend suggested creating a text object for each and one of the available characters, but that’s not exactly optimal, specially when the character list increases, so I’m aiming to solve this using a single text object.
Still, I don’t have any problems using the Coder View, so if you suggest a solution which requires that View, I’ll be glad to hear about it too.
Thanks in advance.
