After correction for multiple testing, one of the t -tests in each of the nine topographic clusters turned out significant [in the right central cluster with t (34) = −3.06, p adj = 0.036, r = 0.46], one marginally significant [in the right posterior cluster with t (34) = −2.86, p adj = 0.056, r = 0.44], and four more neighboring clusters still showed trends [left anterior cluster with t (34) = −2.42, p adj = 0.11, r = 0.38, mid anterior cluster with t (34) = −2.57, p adj = 0.09, r = 0.4, right anterior cluster with t (34) = −2.32, p adj = 0.11, r = 0.37, and mid central cluster with t (34) = −2.74, p adj = 0.07, r = 0.43], always with a larger negativity for sublexically negative high-arousing words.

The sentences
Although, here again, we can only find a trend toward significance, in both analyses the postulated effect is of a medium size, which cannot be neglected (see discussion for why the effect might not be as strong as in previous literature).
T -tests within each of the three laterality clusters only showed a trend toward a difference between neutral low-arousing and negative high-arousing words in the left cluster [ t (34) = −2.17, p adj = 0.12, r = 0.35] with a larger negativity for negative high-arousing words.
