OS: Win10
PsychoPy version: 2026.1.2
Standard Standalone Installation? yes
Do you want it to also run online? no
What are you trying to achieve?: I am running a random dot motion task locally which uses a Cedrus RB-530 to collect directional responses to coherent dot motion going left or right. I have installed the Cedrus plug-in and button presses are being registered when the task is run. My issue is the output datafile. The start and stop times of the Cedrus box are correct and appearing in line with the stimulus. However, I am not sure how the actual reaction time is being recorded. When using a keyboard, I would be given a key_resp.rt column showing the second a response was made. However, I am unsure of the values that are given in the dots_resp.times column for the Cedrus box responses.
What did you try to make it work?: I have checked the functionality of the Cedrus box using Xidon 2 and the timing of the box itself appears to be accurate.
I would please like advice on understanding this output or how to save a .rt style column for Cedrus presses in the datafile.
