Sample trial in the dot probe task. Each trial starts with a fixation cross, typically presented for 500ms. Next, two stimuli, one emotional and one neutral, are presented simultaneously on a computer screen. After a given amount of time (e.g., 500ms or 1000ms) the stimuli disappear and a probe appears in the same location as one of the stimuli. Participants are asked to respond as quickly as possible to the location of the probe (e.g., left or right side of screen) or the type of probe presented (e.g., letter “e” or “f”). Following this is a blank screen for a given inter-trial interval (ITI) before the start of the next trial.
