Figure 1

An example of go and stop trials. (a) During go trials, participants were required to press the 0 key for letter X and 2 key for letter N. (b) During stop-trials, after a variable delay from the onset of the go signal (SSD: Stop-Signal Delay), an image appeared at the centre of screen that signaled participant to withhold their motor response. Arousal matched positive, and negative IAPS images were used as stop-signal. The SSD was set based on a staircase procedure separately for each stop-signal condition to get stop-performance at approximately 50% correct. During low perceptual load trials, the target letter (X or N) was hidden among circular nontarget letters, while during high perceptual load, the target letter was hidden among angular nontarget letters.
