Hi Steve, 

Thanks for your reply! 

Could you please specify the title of the paper that you just mentioned ?

FYI , I am studying both behavioral and electrophysiological responses in different experimental conditions. So, I would like to find the correlation btw single trial ERP and its reaction time. 

 

Best,

Iman

Hi Iman,

 

I guess it depends on the hypothesis you're trying to test and what you mean by relating reaction time to EEG. One approach would be to use the method described in Hauk et al. (2006), which is just to regress the EEG at every (channel, sample) point on the reaction time for the corresponding trial (and any other independent variables of interest); that yields an event-related regression coefficient which can be quantified in the same way as an event-related potential (amplitude, latency, etc.). I am not sure if there's a built-in function for this in EEGLAB (there could be one, I'm just not aware of it), but it's fairly straightforward to do with basic MATLAB built-ins.

 

Best,

Steve

Hi EEGLABers,

Does have  anyone any opinion about how relate signal trial EEG with its corresponding reaction time rather than peak-reaction time relationship? In other word, I am looking for a way to quantify ERPIMAGE and compare it btw two different groups or even subjects. STUDY is not proper for my approach.
