** If you haven't done so, you may need to unzip these files before attempting to run the experiment **
** All three files should be in the same directory, then run timeFrames.psyexp in PsychoPy 1.79 or later **

This PsychoPy experiment allows you to test the refresh timing of your screen at a variety of rates. Feel free to add a BlackBoxToolkit or simple photometer to the system to confirm that the physical times fall exactly as expected from the times reported here.

The key to good timing is that the stimuli are specified in terms of the number of frames rather than as a number of (milli)seconds. It is also helpful to reduce potential interference, and so turning off internet access and bluetooth, and quitting any extra software is recommended.

This experiment is not intended as a demo as such, and it does contain some code segments. These are designed to go and check exactly when the screen flipped for each stimulus onset/offset. These times can be viewed in the resulting data files (summarised in the d

This script allows you to test whether your computer can run 20,000 trials using PsychoPy.
It attempts to run 20 repetitions of 1000 trials, and will save a .psydat files in ./data/ 
for each loop, plus a single .dlm, .csv, .xlsx, and .log files. 

INSTRUCTIONS:
Just run the script from within the coder window (or from the command line) and let it run.
