以10只白卡内诺鸽子为实验对象，采用连续辨别法，每节100次离散试验，校正程序，倾斜线作为刺激。在实验I中，在大约50个回合结束时，在存在刺激的情况下选择替代方案的相对频率偏离了概率匹配值的最大值。在实验II中，4条倾斜线的所有可能组合提供了15个刺激。在70次实验结束时，在存在刺激的情况下选择替代方案的相对频率与该刺激中各成分强化概率的平均值之间的函数呈s形，与Exp. 1和之前的概率学习实验的结果一致。研究结果指出了三种选择行为理论的不足之处。（21 ref.）（PsycINFO Database Record (c) 2016 APA，版权所有）
Conducted 2 experiments with 10 White Carneaux pigeons using a successive discrimination method, 100 discrete trials per session, a correction procedure, and tilted lines as stimuli. In Exp. I, at the end of approximately 50 sessions, the relative frequency of choosing an alternative in the presence of a stimulus deviated from the probability-matching value toward maximizing. In Exp. II, all possible combinations of 4 tilted lines provided 15 stimuli. At the end of 70 sessions, the function relating the relative frequency of choosing an alternative in the presence of a stimulus to the average of the reinforcement probabilities for the components in that stimulus was S-shaped and was consistent with the outcome of Exp. I and of a previous probability-learning experiment. Results point out various inadequacies of 3 theories of choice behavior.(21 ref.)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
