Sorry, my mistake. The correct function should be:
psychoJS.experiment.addData
I’ve got two other pointers that could help your experiment:
- I noticed that some of the images are rather large files (BMP files of 12MB). That can be very heavy on less modern computers and affect your timing accuracy. I recommend recoding them to PNG (or JPG for even better compression)
- In a web-browser, you can log debugging info via the statement below. These will be printed to the browser console. In Chrome and Firefox the console can be opened via F12, though all major browser offer it.
console.log("this is a debug message")
