尽管问题赌徒的流行和研究人类赌博行为所涉及的道德问题，很少有动物赌博模型已经开发出来。在设计动物模型时，有必要确定范式中的行为是否与人类赌博相似。在人类研究中，获胜试验和接近获胜试验后的反应延迟大于明显失败后的反应延迟。韦瑟利和德伦内（Anal Gambl Behav 1：79-89，2007）研究了在动物模拟老虎机赌博中工作的大鼠是否发现了这种模式。他们发现了类似的反应模式，但受试者的行为并没有受到视觉刺激信号的控制。我们使用的老虎机赌博的动物模型解决了韦瑟利和德伦模型中的程序问题，并研究了赌博的幅度和近赢试验的存在是否会影响反应潜伏期和抵抗灭绝。6只雌性Norway Hooded大鼠的反应时间随剂量大小和近赢试验的存在而变化。这些结果与先前的研究一致，也与近赢试验作为条件性验证者的想法一致。
Despite the prevalence of problem gamblers and the ethical issues involved in studying gambling behavior with humans, few animal models of gambling have been developed. When designing an animal model it is necessary to determine if behavior in the paradigm is similar to human gambling. In human studies, response latencies following winning trials and near win trials are greater than those following clear losses. Weatherly and Derenne (Anal Gambl Behav 1:79–89, 2007) investigated whether this pattern was found with rats working in an animal analogue of slot machine gambling. They found a similar pattern of response latencies but the subjects’ behavior did not come under control of the visual stimuli signalling the different outcomes. The animal model of slot machine gambling we used addressed procedural issues in Weatherly and Derenne’s model and examined whether reinforcer magnitude and the presence of near win trials influenced response latency and resistance to extinction. Response latencies of the six female Norway Hooded rats varied as a function of reinforcer magnitude and the presence of near-win trials. These results are consistent with prior research and with the idea that near win trials serve as conditional reinforcers.
