Experimental: IC Training
The experimental arm (ARM1) is a "person-centered inhibitory control" training intervention, or PeCIC.
Between the baseline and endpoint sessions, participants come to our lab 12 times to participate in the training sessions. Each participant is randomly assigned to either the PeCIC training or an active control training. The training sessions will take place approx. every other day for 24 days.
Beginning 2-3 days after the baseline session, the experimental group (will come to our behavioral testing lab to receive the PeCIC training. At 11 sessions spaced one every other day, participants will complete one 8-min run of a modified stop-signal task. The cue on each trial (preceding the "go" signal arrow) will be an image of a personalized risk-cue (PRC) or a neural image.
Behavioral: Person-centered inhibitory control training
A brief, computer-based, multisession training aimed at increasing the connection between environmental risk cues (e.g., cigarettes) and engagement of the brain network for inhibitory control.
Other Name: PeCIC, ARM1
Active Comparator: Control Training
Participants in the active control group (ARM2) of the PeCIC intervention will come to the behavioral testing laboratory to complete an 8-min control task every other day for 12 sessions. This control task is identical to the PeCIC except the auditory stop cues are omitted. All other procedures, settings, and schedules are identical to those in the experimental group. The only difference between the groups is that the active control does not practice IC.
Behavioral: Active behavioral response training
A brief computer-based, multisession training aimed at training behavioral responses to personalized environmental risk cues (e.g., cigarettes) that does not engage the inhibitory control network of the brain.
