The example I have in my research is that both conditions show greater amplitude and latency in the parietal electrode sites than in the occipital ones.

I'm not sure how meaningful this is for my research question, which is primarily concerned with how processing of the two conditions potentially differs (spoiler: no effects of condition!). The effect of electrode sites does not interact with anything, so is just the case that there is greater activity in the parietal sites - can I argue something about the processing involved in both conditions based on this finding?

  • It seems to me that the obvious answer is that different effects (or magnitude differences) between electrode sites is giving you (some) information about the underlying brain area where these conditional differences are taking place. Its certainly not as easy with EEG to say that its the underlying cortical area from your electrodes (depends on reference, volume conduction, and on and on), but its some indication. However, something makes me think that this more obvious answer is not what you are after? – user133804 Oct 10 at 13:45
