mousetrap & counterbalancing positions of response buttons
I have a question regarding how to counterbalance positions of response buttons in an experiment designed with Mousetrap-os.
In this experiment, participants answer questions by clicking on one of the two response buttons in the upper corners of the screen, which are "agree" and "disagree". How can I randomize the positions of the two buttons for each item?
In Kieslich et al. (2019), it was suggested that this can be achieved through the advanced randomization operation shuffle horizontal. Since I am new to programming and OpenSesame, can anyone give me some more detailed instructions?
