Notes. N = 28 for NAcc correlations in the fMRI sample, N = 41 for the remaining correlations. Correlations predicted a priori are highlighted in bold type. Regression analyses were performed on beta weights extracted for each condition (gains, penalties, no-change).

BA24, BA25, and BA32 = log-transformed average delta current density in a priori defined regions of interest in the rACC (see text for details).

MASQ = Mood and Anxiety Symptom Questionnaire administered at the behavioral session (AD = Anhedonic Depression; GDD = General Distress: Depressive Symptoms; GDA = General Distress: Anxious Symptoms; AA = Anxious Arousal).

Functional ROI = log-transformed average delta current density in the functionally defined ROI (i.e., a cluster of 16 contiguous voxels with significant (p < .001) correlations between MASQ AD and log-transformed delta current density, see Figure 1).

NAcc Gains = NAcc responses to monetary gains; NAcc Penalties = NAcc responses to monetary penalties; NAcc Volume = NAcc volume corrected for gender and intracranial volume.
