The delayed-matching-to-sample procedure was modified to study pigeons' spatial memory. Nine pecking keys, arranged as a three-by-three matrix, served as the spatial cues. Trials began with a brief "ready" stimulus (dimming of the houselight). Then a randomly chosen key was lit briefly as a sample. After a short delay the sample key was lit again along with one of the other eight keys. A peck at the key that had served as the sample produced grain reinforcement, where as a peck to the other key produced only the intertrial interval. After delayed matching of key location was learned, the effects of sample and delay duration, number of keys illuminated as sample and comparisons, and organization of three-key samples were studied. Matching accuracy decreased as sample duration decreased, delay increased, the number of locations serving as samples increased, the number and proximity of comparisons increased, and when the three-key samples were "discontinuous" rather than "lines".
延迟匹配样本程序经过修改，用于研究鸽子的空间记忆。九个啄键排列成一个三乘三的矩阵，作为空间线索。试验开始时会有一个短暂的“准备好”刺激（鸽舍灯光变暗）。然后随机选择一个键短暂亮起作为样本。经过短暂延迟后，样本键与其他八个键之一再次亮起。啄向曾作为样本的键会得到谷物强化，而啄向其他键只会产生试验间隔。在学会了键位置的延迟匹配后，研究了样本和延迟持续时间、作为样本亮起的键的数量以及比较、以及三键样本的组织方式的影响。随着样本持续时间缩短、延迟增加、作为样本的位置数量增加、比较的数量和接近程度增加，以及当三键样本是“不连续的”而非“连续的”时，匹配准确率会下降。
