Although it is not directly comparable because clusters may obviously differ, I guess that is the best I can do.<o:p></o:p></span></p>

<br>
If I understand correctly:<br>
<br>
For each subject you have <b>four </b>conditions - A_face, A_house, B_face, B_house<br>
You compared A_face with A_house and there was a significant difference<br>
You compared B_face with B_house and there was also a significant difference<br>
<br>
Right?<br>
<br>
Now the reviewers want you to test if there is a difference between A and B<br>
<br>
You could:<br>
<br>
For every subject, create an average of A_face and A_house (let's call it A_avg)<br>
For every subject, create an average of B_face and B_house (let's call it B_avg)<br>
Compare A_avg and B_avg using depsamplesT<br>
<br>
Best,<br>
Tom<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="color:black">I am comparing event-related oscillatory responses in two conditions A and B. In each condition, subjects have been presented with two different stimulus types, let’s take “houses” and “faces” as an
easy example. What I have done so far is I compared the oscillatory responses to the two stimuli WITHIN each condition using cluster based permutation tests (depsamplesT; frequency range 4-15 Hz, 173 electrodes, 6 time bins). What I find is significant differences
between “houses” and “faces” within each condition. However it seems that in higher frequencies there is also a difference between conditions A and B. Now reviewers have asked me to test this difference statistically. Unfortunately, I do not really know how
to go about…any suggestions are highly appreciated!</span><span style="color:black"><o:p></o:p></span></p>
