Because alcohol use can be influenced by parental alcohol use, the Korean version of the Children of Alcoholics Screening Test (CAST-K, Jones, 1983; Kim et al., 1995) was administered to identify whether the participants’ parents had a history of an AUD; those who scored ≥6 points on the CAST-K were excluded. To control for intelligence, anxiety, and depression, the Korean Wechsler Intelligence Scale (K-WAIS; Yum et al., 1992), Spielberger’s State-Trait Anxiety Inventory (STAI; Spielberger et al., 1970), and Self-Rating Depression Scale (SDS; Zung, 1965) were administered, respectively. Also, the Structured Clinical Interview for DSM-IV-Non patient edition (SCID-NP, First et al., 1996) was administered to ensure that participants had no neurological or psychiatric disorders and no drug/alcohol abuse. Only right-handed participants were included in the study.
