In five experiments, choice responding of female human adults was examined, as a function of variations in reinforcer amount and reinforcer delay. Experiment 1 used a discrete-trials procedure, and Experiments 2, 3, 4, and 5 used a concurrent variable-interval variable-interval schedule. Reinforcer amount and reinforcer delay were varied both separately and together. In contrast to results previously reported with pigeons, the subjects in the present experiments usually chose the larger reinforcers even when those reinforcers were delayed. Together, the results from all the experiments suggest that the subjects followed a maximization strategy in choosing reinforcers. Such behavior makes it easy to observe self-control and difficult to observe impulsiveness in traditional laboratory experiments that use adult human subjects.
在五项实验中，研究了成年女性的选择反应，该反应是强化物数量和强化物延迟变化的函数。实验1采用离散试验程序，实验2、3、4和5采用并发可变间隔可变间隔时间表。强化物数量和强化物延迟分别和一起进行了变化。与先前用鸽子报道的结果相反，本实验中的受试者通常选择较大的强化物，即使这些强化物被延迟。所有实验的结果共同表明，受试者在选择强化物时遵循最大化策略。这种行为使得在使用成年人类受试者的传统实验室实验中很容易观察到自我控制，而很难观察到冲动行为。
