Irrational Beliefs and Behavioral Misregulation in the Role of Alcohol Abuse Among College Students

Two hundred three alcohol-using college students completed a questionnaire on their levels of alcohol use, moderate to severe problems with alcohol use, and measures of life stress, impulsivity, compulsivity, irrational beliefs, and depression. While impulsivity significantly predicted both alcohol use and problems, stress, compulsivity, irrational beliefs, and depression were found to only be significant predictors of alcohol use problems. When irrational beliefs, impulsivity, and compulsivity were combined to form an irrational coping scale, this construct was found in multiple regression analyses to completely mediate the effect of stress on alcohol use problems, while depression was a partial mediator of this effect. Results were interpreted in terms of Rational Emotive Behavior Theory.     

Serial-position effects on a free-recall task in bilinguals

In this study, we examined mechanisms that underlie free-recall performance in bilinguals' first language (L1) and second language (L2) through the prism of serial-position effects. On free-recall tasks, a typical pattern of performance follows a U-shaped serial-position curve, where items from the beginning of the list (the primacy effect) and items from the end of the list (the recency effect) are recalled with higher accuracy than items from the middle of the list. The present study contrasted serial-position effects on the free-recall task in Korean-English bilinguals' L1 vs. L2 and examined the relationship between an independent working memory (WM) measure and serial-position effects in bilinguals' two languages. Results revealed stronger pre-recency (primacy and middle) effects in L1 than in L2, but similar recency effects in the two languages. A close association was observed between WM and recall performance in the pre-recency region in the L1 but not in the L2. Together, these findings suggest that linguistic knowledge constrains free-recall performance in bilinguals, but only in the pre-recency region.
