Extended Data Figure 1

Mean square-root-normalized skin conductive responses for the CS+ and CS− for each group. Results provide confirmation that the fear-conditioning manipulation was effective at generating higher arousal in CS+ than CS− trials. Error bars are s.e.m. **P<0.01, two-tailed t-tests.
