This is a shortened version of the paradigm previously utilized by our group (Marsh & Blair, 2008). During each trial the participant is asked to decide the gender of the face displayed. The face either demonstrates neutral affect or a morphed intensity of fear (50%, 100% or 150%). A trial involves: the presentation of a face (1500 ms) and then a fixation point (1000 ms). There is one run of this task, with 120 face trials (30 neutral, 30 50% fear, 30 100% fear and 30 150% fear) and 60 fixation point trials. In addition, there are 15 seconds of fixation point trials at the beginning and end of the run. Task duration is 8 minutes.
