억제기능 결함과 도박중독의 관계 : 카지노 도박중독자들을 중심으로

초록

Researches on gambling issues from neuro-cognitive perspective are keep increasing and developing as years pass by. This study was to investigate the relationship between deficiency on inhibition and gambling problems. According to the Dillon and Pizzagalli(2007) 's multi-dimensional theory, this study divided inhibition into cognitive, emotional and behavioral inhibition. The participants were 24 pathological casino gamblers who were all males as a gambling addiction group, and 21 men who were sampled in community as a control group. All participants completed K-NODS, working memory test, and 3 tasks which were designed to evaluate inhibitory functions of cognitive, emotional, and motor responses. The results were as follows; On Stroop Negative Priming Task for evaluating cognitive inhibition, the gambling addiction group slowed more than the control group on their reaction time by failing inhibiting of distractor stimulation. On Emotional Go/No-Go Task for evaluating inhibition of emotional responses, the addiction group reacted more incorrectly, made more error of false alarm, and showed faster(impulsive) reaction time than the control group on sad emotional task. And they were shorter on stop-signal delay time of Stop-Signal Task for evaluating behavioral(motor) inhibition synthesis, the addiction group showed defection for inhibiting prepotent motor responses and had difficulty for inhibiting distractor stimulation. These results suggest that gambling addiction group has comprehensive defection in terms of inhibitory function.
