Cue-reactivity task. Top: Representation of the 500 msec cue task in its entirety. There were 120 trials per half, 24 in each of 4 cue categories plus 24 “null” targets (grey screen with cross-hair). Middle Top: Example order of targets in first and second half. Targets were pseudo-randomly presented (no more than three presentations of a target in a row) in the first half, and then that order was quasi-randomized in the second half. N=Neutral, C=Cocaine, A=Aversive, S=Sexual, “+” = Null. Middle Bottom: Examples of actual (neutral, cocaine) cues and cues (sexual, and aversive) that were similar (to IAPS images) used in the task. Bottom: Actual presentation of targets, complete with 1500 msec of ISI (grey screen with crosshair).
