Table 3. Means and SD of SAM(subjective assessment of anxiety) and N-back (working memory capacity). The three rehydration conditions are collapsed since no significant differences between them were found.

*The participants assessed their degree of anxiety on the three aspects above on a scale from 1–9. **The tests were divided into 2 blocks. In the first block N=1, in the second N=2. Perform: the percentage correct answers, RT: response time in ms. N=12
