Simstim

Setup

1. Install the Arduino Desktop IDE
2. Go to the Cthulhu GitHub repo and download ZIP
3. Open the Arduino IDE, go to Sketch > Include Library > Add .ZIP Library, and select the .zip file downloaded in the previous step
4. Setup Anaconda environment with conda env create -f environment.yml
5. Set the default port value in simstim/cthulhu.py. If you don't know the port, make sure the Arduino is connected to your computer and run ls -lha /dev/tty* (it will probably look like /dev/tty.usbmodem).

Usage

1. In the Arduino IDE, open File > Examples > Cthulhu-master > SerialInput and run the program
2. Activate Anaconda environment with conda activate simstim
3. Run python study.py
4. Click on circle to toggle prediction. If you think the electrode is on, toggle it black. Otherwise, leave it gray.
5. When you're ready to submit your prediction, hit Enter. The difference between your prediction and the true pattern will be revealed.

• Gray: predicted off, actually off
• Green: predicted on, actually on
• Blue: predicted off, actually on
• Red: predicted on, actually off

6. Once you are done looking at the results, hit the right arrow key. The display will be reset, and the electrodes will be reset to a new pattern.
7. When you want to end the experiment, click the X button at the top of the experiment window
