As the world's fastest growing addiction, Internet addiction should be studied to unravel the potential heterogeneity. The present study is set to examine reward and punishment processing in Internet addicts as compared to healthy controls while they subjectively experience monetary gain and loss during the performance of a guessing task. The results showed that Internet addicts associated with increased activation in orbitofrontal cortex in gain trials and decreased anterior cingulate activation in loss trials than normal controls. The results suggested that Internet addicts have enhanced reward sensitivity and decreased loss sensitivity than normal comparisons. (C) 2011 Elsevier Ltd. All rights reserved.
