How to stop trial with press of a button and then restart trial after pressing button again

Coding
1

Hello everyone,

I have a six trial experiment. In each trial, a video is played and two stimuli (a beep and a picture) pop-up during it at randomised ISI.

The experiment is meant for infants so I would like to be able to stop the experiment by pressing space bar when they stop paying attention or something happens etc and subsequently, restart the trial when I press the space bar again. Preferably a new pause screen should come up when I press the stop button. Much appreciate any help and/or example code to do this!

Hi @Achilles,

Please find attached a modification of something I coded previously.

If you press space during the trial, the trial will end and a pause trials starts. You can end the pause trial by pressing space again and the previous trial will be repeated.

Hope this helps.

Hello Jan,

Iā€™m not so sure how to make your code work with my experiment. Iā€™ve tried a couple of things but for starters I get ā€˜repeatTrialLoopā€™ not defined

Here are the experiment files Iā€™m working on

Hi @Achilles,

The problem is that you added the code to the ā€œBegin Experimentā€ instead of the ā€œBegin Routineā€ tab.

You also need to increase the ā€œnRepsā€ for the repeatTrialLoop to something rather high (e.g., 100).

Finally, you need to make sure that ā€œForce end of Routineā€ is ticked for the pause trial.
