FIGURE 1.

Revised MET paradigm used in the fMRI experiment. Three blocks for CE, EED, and EEI were presented and in a balanced order. In each block, after 3 s of cue presentation, a jittered fixation (4–6 s) followed. Stimuli were shown for 3 s followed by another jittered fixation (3–5 s) and then a 5 s rating phase in order to separate the viewing and rating phases for fMRI analysis. Each block lasted for 173 s. There was a total of six runs with each run including three blocks, one block for CE, one for EED, and one for EEI.
