视觉短时记忆在指导行为中起着关键作用，视觉短时记忆容量的个体差异强烈地预示着较高的认知能力。为了提供更广泛的进化背景来理解这种记忆系统，我们直接比较了鸽子和人类在变化检测任务中的行为。虽然鸽子的存储容量比人类低，失效率比人类高，但这两个物种都在短期记忆中存储多个项目，并且符合相同的基本性能模型。因此，尽管它们的进化历史和神经结构非常不同，鸽子和人类具有功能相似的视觉短期记忆系统，这表明视觉短期记忆的功能特性在这些遥远的物种中受到类似的选择压力。
Visual short-term memory plays a key role in guiding behavior, and individual differences in visual short-term memory capacity are strongly predictive of higher cognitive abilities. To provide a broader evolutionary context for understanding this memory system, we directly compared the behavior of pigeons and humans on a change detection task. Although pigeons had a lower storage capacity and a higher lapse rate than humans, both species stored multiple items in short-term memory and conformed to the same basic performance model. Thus, despite their very different evolutionary histories and neural architectures, pigeons and humans have functionally similar visual short-term memory systems, suggesting that the functional properties of visual short-term memory are subject to similar selective pressures across these distant species.
