Overview and timeline of the experimental design. All participants went through both conditions. For half of the participants the first part of the experiment (Upper) consisted of the stress condition, whereas for the other half the first part consisted of the neutral condition. Preparation took place outside the scanner. Between the second and third movie n-back data were acquired, which are not reported here. The numbers below the movies and tasks indicate the time in minutes. P, PANAS; S, saliva sampling. Acquisition of each PANAS and each saliva sample took 5 min, thereby causing a 20-min gap between conditions.
