In gambling situations, we found a paradoxical reinforcing effect of high-risk decision-making after repeated big monetary losses. The computerized version of the Iowa Gambling Task (Bechara et al., 2000), which contained six big loss cards in deck B', was conducted on normal healthy college students. The results indicated that the total number of selections from deck A' and deck B' decreased across trials. However, there was no decrease in selections from deck B'. Detailed analysis of the card selections revealed that some people persisted in selecting from the "risky" deck B' as the number of big losses increased. This tendency was prominent in self-rated deliberative people. However, they were implicitly impulsive, as revealed by the matching familiar figure test. These results suggest that the gap between explicit deliberation and implicit impulsivity drew them into pathological gambling.
在赌博情境中，我们发现多次大的金钱损失后，高风险决策会产生矛盾的强化效应。我们在正常健康的大学生中进行了包含 B' 卡组中 6 张大损失牌的电脑版爱荷华赌博任务（Bechara 等人，2000）。结果表明，A' 和 B' 卡组的总选择数随着试验次数的增加而减少。然而，B' 卡组的选择数并没有减少。对卡片选择的详细分析表明，一些人在大损失增加的情况下，仍然坚持从“风险”的 B' 卡组中选择。这种倾向在自评深思熟虑的人中尤为明显。然而，正如匹配熟悉图形测试所揭示的那样，他们实际上是冲动的。这些结果表明，明确的深思熟虑和隐含的冲动之间的差距使他们陷入了病态赌博。
