In the section Methods, subsection Statistical analyses, we erroneously reported the use of one-sided t tests. In fact all tests results in this article are based on two-sided statistical analyses, using the corresponding more conservative p values.

Also in the section Methods, subsection Participants, in the paragraph on sample size, one-sided dependent sample t test should be read as two-sided dependent sample t test.
