Analysis of interindividual differences
To investigate the effect of the CTQ‐EN on the neural responses toward images of different emotional valences as well as the interaction of CTQ‐EN with OXT administration, exploratory analyses were conducted. The extracted values of each ROI were entered into a separate 2 × 3 ANOVA with drug (OXT and placebo) and condition (negative, neutral, and positive) as within‐subject factors and the respective questionnaire as a covariate. Subsequently, CTQ‐EN scores were correlated with the extracted ROI parameters to describe the interaction effects.
