Design A case–control study design. Setting A drug misuse treatment centre in Taiwan. Participants Eighty-eight male AHMs and 48 male controls. Measurements Four parameters representing the attention to wins, learning rate, response sensitivity and incentive of heroin-related stimuli from the modified Go/NoGo discrimination task. Finding A modified cue-dependent learning (CD) model with four parameters representing attention to wins, learning rate, response sensitivity and incentive of heroin-related stimuli had a lower value of the sum of Bayesian information criterion (showing a better fit) than the original CD model (9555.50 versus 11 192.22, P < 0.001). The AHM group had a higher value of the heroin-incentive parameter than the control group (0.26 versus −1.66, P < 0.05). The attention to wins and heroin-incentive parameters were associated positively with total commission rate and negatively with total omission rate in the AHM group (P < 0.001). Conclusions Male abstinent heroin misusers appear to be more influenced by heroin-related stimuli during decision-making than males with no history of heroin misuse. | 關聯: | Addiction,Volume 109, Issue 8, pages 1355–1362 | 資料類型: | article | DOI: | http://dx.doi.org/10.1111/add.12591 |
