To examine differences between two versions of the Iowa Gambling Task (IGT).
A total of 282 undergraduate students completed one of two versions of the IGT: the original version from 1994 (n = 132), or the 2007 version available through Psychological Assessment Resources (PAR) (n = 150).
PAR (2007 version) IGT participants decided more advantageously (i.e., selected more from the small immediate reward but long-term positive/gain decks than the large immediate reward but long-term negative/loss decks) than original IGT participants during Trials 21-60. This difference was likely due to fewer Deck B selections by the PAR IGT participants during the early (Trials 1-40) and later (Trials 41-100) trials.
The PAR IGT may result in a greater ability to make future-oriented, advantageous decisions more quickly than on the original IGT. Implications for future assessment of decision-making impairments in clinical and research settings are discussed.
检验爱荷华赌博任务（IGT）两个版本之间的差异。
共有282名本科生完成了IGT两个版本中的一个：1994年的原始版本（n = 132），或通过心理评估资源公司（PAR）获得的2007年版本（n = 150）。
在第21 - 60次试验中，PAR（2007年版本）IGT参与者比原始IGT参与者做出了更有利的决策（即，从小额即时奖励但长期积极/收益牌组中选择的次数多于大额即时奖励但长期消极/损失牌组）。这种差异可能是由于PAR IGT参与者在早期（第1 - 40次试验）和后期（第41 - 100次试验）试验中选择B牌组的次数较少。
与原始IGT相比，PAR IGT可能使人们更有能力更快地做出面向未来的有利决策。讨论了其对临床和研究环境中决策障碍未来评估的影响。
