Attentional bias modification training
Placebo control
Attention bias modification training (ABMT) is a a variation of attention tasks to modify attentional biases, in which a probe always appears in the location of relatively positive stimuli after the two stimuli, one neutral and one emotional, were simultaneously presented. Participants complete 8 sessions (320 trials each with 20 minutes) over two weeks of neutral ABMT to shift attention toward neutral, in which a probe appeared in the location of neutral with 90% probability, and sadness-related with 10% probality. At a 9-week follow-up, participants completed 4 more sessions (480 trials each with 30 minutes)over two weeks of positive ABMT to shift attention toward positive words,in which a probe appeared in the location of 67% positive or 33% neutral.
The placebo ABMT was identical to the active ABMT, but shifted toward neutral (50%) or sad (50%) stimuli equally often (i.e., 50/50 training).
