Second, in the case of significant ERS or ERD (one-tailed t-test) in at least one task, analyses of variance (ANOVAs) with repeated measures were conducted on the three-level factor TASK CONDITION (control pre, control post, cueing), the two-level factor ELECTRODE HEMISPHERE (right or left hemisphere) and the two-level factor S1 STIMULUS SIDE (right or left index finger).
This study used a mixed factorial design (Mood Induction: Neutral, Stress; Cues: Neutral, Food) with repeated measures on time (Baseline, Post-Mood Induction, Post-Cue Exposure).
During the task, both post-cue and post-target event-related potentials (ERPs) were recorded by means of a high spatial resolution EEG system.
In the results of the post-cue analysis, the P3a and P3b were identified as two distinct ERP markers showing distinguishable spatiotemporal features and reflecting automatic and voluntary a priori expectancy generation, respectively.
Additionally, post-cue contingent negative variation (CNV) and post-target P3 modulations were observed as common markers of voluntary and automatic expectancy implementation and response selection, although partially dissociable neural networks subserved these two mechanisms.
In addition, when assessing correlates of post-cue exposure craving, negative mood and procurement of prescription opioids from non-medical sources were the only measured variables that were significantly associated with overall craving and/or any of the craving measure's subscales.
The CWS included three sets of rules, posted cues to indicate the rules students are expected to be following at that time, and transition procedures for altering activities and rules.
We only measured the retro-cue and post-cue conditions in this experiment.
Only the retro-cue condition (Fig. 6d) and the post-cue condition (Fig. 6e) were presented.
