Does psychoPy by default record reaction time?

Builder

I have completed building my experiment and I would like to go ahead and run my experiment online. my question is: Does psychoPy by default record reaction time? I basically want PsychoPy to start measuring participants reaction time from when a video ends (end of video) to when they click on the option they think is correct. Any help to make sure I have everything set properly.

OS (e.g. Win10):
PsychoPy version (e.g. 2024.2.4 Py 3.8): PsychoPy 2025.2.4
Standard Standalone Installation? (y/n) yes
Do you want it to also run online? (y/n) yes
What are you trying to achieve?: I want to make sure that reaction time is measured.

What did you try to make it work?: Not Applicable

Link to the most relevant existing thread you have found:

What specifically went wrong when you tried that?: Not applicable ( I have not tried anything)
Include pasted full error message if possible. “That didn’t work” is not enough information.

Hello @MSGG

You need a reaction device, keyboard, mouse, button-box, aso. You need to set it to record the reaction. This is the default. The trial-option of the loop should be checked. This is also the default.
