Updated iOS example experiment

Support
1

Hi Michael,

I’ve attached an updated version of the iOS example experiment. There are two main changes:

  1. The experiment now tracks the number of premature, correct, incorrect, and ignored responses, as well as the total number of trials.

  2. When first run, the experiment shows a “Start data collection” button alongside the button to start a trial. You can perform trials normally without pressing the button. Once you do press it, the variable collecting_data is set to true, and all the result counts are reset to zero. The button won’t reappear until you stop and restart the experiment.

    At the moment, the value of collecting_data isn’t used anywhere. However, you could use it to decide whether to upload results to Dropbox, for example.

If you have any questions, please let me know.

Chris

Hi Michael,

I found and fixed a small bug in the protocol. The bug could cause the correctness of the subject’s first response, after starting data collection or stopping and restarting the experiment, to be assessed incorrectly. I’ve attached the updated experiment.
