Hi, I am using an online task where timings are very sensitive. The inevitable timing variations that kick in thanks to differences in PC processing speeds and refresh rates means that i may have a problem. It occurred to me though that Inquisit audit data may allow for trial by trial and PC by PC timing differences to be modelled and controlled for.

I therefore have a couple of questions.

1) Am I mad to think this will work.
2) Is it possible to get identifying information like a participant number or prolific academic id code into the audit data itself or its filename.

Many thanks for any help
Peter

I don't know! What I'd do alternatively or in addition is just log the various device-speciffic properties to the raw and/or summary data file.

Timing information for stimuli you should already have in the data (stimulusonset columns), if you're not logging those, I'd recommend you do so. In addition, you can log a whole bunch of timestamp information which may be useful for modelling differences.

Not in the data itself, but you'll have the subject ID in the file name:
