design

trial

  • fixation: 0-1500ms (1500)
  • facestim: 1500-4500ms (3000)
  • dotloc: 4250-14250ms (10000)
  • delay: 14250-14500ms (250)

task

  • nine blocks of 198 trials
  • two conditions (subject does same version each time):
    • active training: -- probe [target] 80% neutral stim location -- probe [target] 20% dysphoric [sad] stim location
    • placebo: -- probe [target] 50% neutral stim location -- probe [target] 50% dysphoric [sad] stim location

structure

  • 198-trials (total), 9-blocks, 22-trials [12 - pofa; 10*9 - iaps]
  • minimal duration: 17 minutes + 4 minute break + 5 minute practice ** (12 pofa_trials * 9 blocks * (4.5 second stim) + ** (10 iaps_trials * 9 blocks * (6 second trial))
  • maxinum duration: 50 minutes [include max response time]: 17 minutes + 4 minute break + 5 minute practice ** (12 pofa_trials * 9 blocks * (4.5 second stim + 10 second response) + ** (10 iaps_trials * 9 blocks * (6 second trial + 10 second response))
