本研究使用了一种新的延迟不匹配到位置的任务来比较年轻和老年比格犬的视觉空间学习和记忆，该任务使用了3个而不是2个空间位置，这显著增加了难度。在习得方面存在着显著的年龄差异。大多数年长的狗没有学习这项任务，与年轻的狗相比，那些学习的狗表现出了学习障碍。与年轻犬相比，老龄犬的最大工作记忆容量也有所降低。对单个犬类的反应模式分析表明，缺陷与使用无效的策略和修改策略时缺乏灵活性有关。
This study used a novel delayed nonmatching-to-position task to compare visuospatial learning and memory in young and aged beagle dogs (Canis familiaris), The task used 3, rather than 2, spatial locations, which markedly increased difficulty. There were striking age differences in acquisition. Most of the aged canines did not learn the task, and those that did showed impaired learning when compared with the young canines. The aged canines also showed reduced maximal working memory capacity compared with the young canines. Analysis of the response patterns of individual canines indicated that the deficits were related to the use of ineffective strategies and inflexibility in strategy modification.
