That&#x27;s what I thought they meant, too, but it is not. From the research article (<a href="http:&#x2F;&#x2F;www.pnas.org&#x2F;content&#x2F;106&#x2F;26&#x2F;10587.full" rel="nofollow">http:&#x2F;&#x2F;www.pnas.org&#x2F;content&#x2F;106&#x2F;26&#x2F;10587.full</a>):<p>&quot;The means display somewhat more variation, as shown in Fig. 2. Danish has the slowest response time on average (+469 ms) and Japanese has the fastest (+7 ms). The mean response offset for the full dataset is +208 ms, and the language-specific means fall within ≈250 ms either side of this cross-language mean, approximately the length of time it takes to produce a single English syllable (37).&quot;<p>The point, I think, is that these means are close compared to the tails: <a href="http:&#x2F;&#x2F;www.pnas.org&#x2F;content&#x2F;106&#x2F;26&#x2F;10587&#x2F;F1.large.jpg" rel="nofollow">http:&#x2F;&#x2F;www.pnas.org&#x2F;content&#x2F;106&#x2F;26&#x2F;10587&#x2F;F1.large.jpg</a>
