reaction time logged between visual target and the key press

Hi Yuting - do you mean the reported RT isn't trial_duration - the length of the audio file? Not even approximately? It will never be exactly the same as there are measurement errors (on the millisecond level) and the buffering time involved.

I'm also not quite sure of what you mean by "actual RTs". Can you elaborate a bit? Thanks!

Hi Ting, 

No, the reported RT isn't trial_duration - the length of the audio file, not even approximately (at least for most of the trials). 

What I meant by "actual RTs" is just the trial_duration - the length of the audio file  but maybe it's due to the measurement errors plus the buffering time? As defined by FF grammar book, the rt logged for key press responses is the duration between two key presses, but what we want is the duration between the visual target and the key press. 

Let me know if this makes sense to you!

Thank you,
Yuting
