Methods

Participants

This study was approved by the University of California San Diego (UCSD) and the San Diego State University (SDSU) Institutional Review Boards and all subjects signed informed consent. Initially, a sample of SDSU undergraduate psychology students participated in mass screening using the Spielberger Trait Anxiety Questionnaire (Spielberger 1983). All subjects were subsequently interviewed with a structured diagnostic interview (SCID) (Fist et al. 1995), modified to enable us to document the presence of sub-threshold anxiety and mood disorders. Only subjects who did not have a DSM-IV (American Psychiatric Association 1994) diagnosis were included in this study. Twenty-six subjects were studied, 17 females and nine males. The average age of the subjects was 19.0 (18–26) years old and they had an average of 12.8 (11–15) years of education. All subjects were trained to perform the emotion face-processing task prior to testing during fMRI scanning and received $50 for participation. No restrictions were placed on the consumption of caffeine-containing beverages; none of the subjects were smokers.
