The ability of pigeons to form configural stimulus representations was assessed in two operant discrimination experiments. In Experiment 1 the transverse patterning problem of Spence (1952) was trained. In Phase 1, subjects had to choose stimulus A on A + B - trials; B + C - trials were added in Phase 2. In Phase 3, the first two pairs were combined with C + A - trials. The success of the subjects was simulated by a model assuming that elemental and configural stimulus representations coexist in a stable proportion, even in the phases of the experiment which do not require configural stimulus representations for successful solution. Experiment 2 replicated the first two phases of Experiment 1, but trained A + C - in Phase 3. Comparison of the results of this experiment with simulations of the model showed that elemental and configural stimulus representations coexisted in similar proportions as in Experiment 1, even though they were not necessary for successful task solution.
在两项操作性辨别实验中评估了鸽子形成构型刺激表征的能力。在实验1中，训练了斯彭斯（1952）的横向模式问题。在第1阶段，受试者必须在A + B - 试验中选择刺激A；在第2阶段增加了B + C - 试验。在第3阶段，前两对与C + A - 试验相结合。通过一个模型模拟受试者的成功情况，该模型假设即使在实验阶段不需要构型刺激表征就能成功解决问题，元素性和构型刺激表征也以稳定的比例共存。实验2重复了实验1的前两个阶段，但在第3阶段训练了A + C - 。将该实验结果与模型模拟结果进行比较表明，即使元素性和构型刺激表征对于成功完成任务不是必需的，但它们仍以与实验1中相似的比例共存。
