I would like to build an experiment in which participants are shown colored squares in the computer screen. Some of these visual stimuli will occasionally be paired with a mild electric shock to the wrist (reinforced presentation of stimuli), whereas others will not be paired with these shocks (non-reinforced presentation of stimuli). I will be assessing the skin conductance response of participants during all non-reinforced presentation of stimuli.
I have a computer with SuperLab 4.5 connected to a stim tracker via a USB cable. The stim tracker is connected to a STP100C interface (Biopac) via a CBL STP ribbon cable. The STP100C is connected to a GSR100C, a UIM100C, and an MP150 (all from Biopac), which in turn are connected to another computer with Acqkowledge 4.2 (Biopac systems). I also have a Grass stimulator that will be connected to the MP150 via a BNC cable.
My plan was to program SuperLab to trigger data collection in the Aqckowledge 4.2, which in turn will trigger electrical shocks (in trials with reinforced presentation of stimuli). However, I have not been able to do so and I don’t know what I’m doing wrong. Can anyone help me?
