The affective task used here was an adapted version of the paradigm described in previous work. During each trail the participant is asked to decide how many numbers are displayed on the screen, instead of the value of the number. For congruent trials, the numbers were displayed with the same numerosity and number value (e.g., three 3s). For incongruent trials, the numbers were displayed with different numerosities and number values (e.g., four 3s). The individual numerical stimuli consisted of three, four, five, or six 3s, 4s, 5s, or 6s randomly presented within a 9-point grid. There are an equal number of congruent trials and incongruent trials (48 each for a run). These number pictures were preceded and followed by emotional stimuli pictures consisting of 48 positive, 48 negative, and 48 neutral pictures selected from the International Affective Picture System. A trial involves: the presentation of an emotional stimuli (400ms), a numerical display (400ms), the same emotional stimuli (400ms), and a blank (1300ms). Subject completed two runs, generating 288 picture-trial events (32 in each 9 categories) and 96 fixation points to generate a baseline.
