STAI (Spielberger, 1983) rates anxiety-related statements using a 1 – 4 scale (“not at all” to “very much so”) with two subscales differentiating “trait” from “state” anxiety. After the fMRI scanning session, subjects rated a selection of the IAPS stimuli on valence and arousal using the Self-Assessment Manikin (SAM) (Bradley et al., 1994). No significant sex by case interaction effects.
