数据显示，人类和非人类的能力，以确定刺激，沿沿着一个单一的维度变化是严重有限的。增加空间未分化刺激的维度可以提高表现。然而，这种改善是微不足道的相比，观察到的空间复杂的刺激，如图片，被提出的识别。这里提出的记忆和决策过程的理论说明表明，虽然工作记忆中可以保存的项目数量因物种而异，但可以识别的项目数量更多地取决于刺激的特征，而不是生物体进行识别。
Data are presented showing that humans and non-humans are severely limited in their ability to identify stimuli that vary along a single dimension. Increasing the dimensionality of spatially undifferentiated stimuli improves performance. However, this improvement is trivial compared to that observed when spatially complex stimuli, such as pictures, are presented for identification. The theoretical account of memory and decision processes presented here suggests that, while the number of items that can be held in working memory varies among species, the number of items that can be identified depends more upon the characteristics of the stimuli than upon the organism making the identification.
