How can I measure reaction time in milliseconds?

Hi Sam,

I understand that PsychoPy gives your response data in seconds.

In the Builder, to obtain your data in milliseconds, just add a Code component at the begining of your Routine, and in the End Routine window insert the following line:

thisExp.addData('StimuliResp.RT in ms', StimuliResp.rt * 1000)

where “StimuliResp” is the name for your object to respond to the stimuli (e.g., keyboard; the “in ms” note is useful to distinguish this variable in your data sheet).

Good luck with your experiment!
