摘要 爱荷华赌博任务近年来得到了广泛运用,但对此任务的研究结果的阐释却也争论颇多:有的研究者支持用体细胞标记假说来解释任务结果;有的研究者却认为爱荷华赌博任务本身的成分复杂性是影响任务成绩的关键因素。本文述评了这些争论观点,进一步指出了爱荷华赌博任务的自身设计和结果处理等方面所存在的问题,比如任务中纸牌的位置不平衡、心理物理法测量及数据统计方法不精确等,并针对这些问题提出了几点建议。 One of the most frequently used neuropsychologieal tasks to assess decision-making in ambiguous situation was the Iowa G-ambling Task developed by Bechara and his colleagues. But many questions had no answer on this task. Some researchers found that the Iowa Gambling Task exclusively measured decisions under ambiguity and explained how the somatic makers in body affect decision-making. Other researchers found that it could also be that complexity of componants in the IGT exerted crucial influence upon whether or not subjects figure out the rules during performing the task. There were other well-specified and parsimonious explanations that can equally well account for the IGT data, such as working memory, controlling and shifting, and so on. All these issues had been reviewed and problems had been pointed, including the order of the decks, the tools of analyzing data. At last, some advice had been given for the future study.
