we need to set up a study in whcih participants press a response buton with thier foot (via a cedrus response pad placed under the table), or with their finger via a cedrus response pad placed on the table. Is it okay to plug two response pads into two USB ports and use them for input? On any given trial only one button will be pressed.
From a previous thread it seems like you can do this IF they are different models of response pad.
Please advise!
