The ability of salient cues to serve as powerful motivators has long been recognized in models of drug addiction, but little has been done to investigate their effects on complex decision making. The Cued rat Gambling Task (CrGT) is an operant behavioural task which pairs salient, audiovisual cues with the delivery of sucrose pellet rewards on complex schedules of reinforcement that involve both sugar pellet 'wins' and timeout penalty 'losses'. The task was designed with the intention of providing insight into the influence of such cues on decision making in a manner that models human gambling.
显著线索作为强大动机的能力在药物成瘾模型中早已得到认可，但在研究它们对复杂决策的影响方面却做得很少。线索提示大鼠赌博任务（CrGT）是一种操作性行为任务，它将显著的视听线索与蔗糖颗粒奖励的发放配对，采用复杂的强化时间表，其中包括糖颗粒“赢”和超时惩罚“输”。设计该任务的目的是以模拟人类赌博的方式深入了解此类线索对决策的影响。
