1: Experimental |
Behavioral: Attention Modification Program
The AMP protocol includes twelve 30-min sessions delivered over a 6-week period. During each session, participants will see 240 trials consisting of the various combinations of probe type (E or F), probe position (top or bottom), and word type (Neutral or Trauma). Of the 240 trials, 48 include only neutral words: 2 (probe type) X 2 (probe position) X 12 (word pairs). The remaining 192 trials include one neutral word and one trauma word: 2 (probe type) X 2 (probe position) X 2 (repetitions) X 24 (word pairs). On trials where participants see one neutral word and one trauma word (i.e., 80% of the trials), the probe always follows the neutral word.

2: Placebo Comparator |
Behavioral: Attention Modification Program
The placebo condition (PC) will be identical to the AMP condition except that during the presentation of the trials where a threat word is present, the probe will appear with equal frequency in the position of threat and neutral words. Thus, neither threat nor neutral words have signal value with regard to the position of the probe.
