两项研究使用刺激跟踪范式来测试大鼠是否对结构化序列模式的基于规则的形式属性敏感。戴头巾的老鼠通过按压6个指示灯下的杠杆来跟踪16个元素的闪光模式。在实验1中，老鼠追踪的模式与之前人类受试者使用的模式相似，并产生了非常相似的结果。错误和反应遗漏更多地发生在结构“组块”的边界，而不是组块内，错误往往反映了对下一个组块的预期或对前一个组块的推断。在实验2中，时间“措辞”线索鼓励不同的群体编码的模式作为一系列的“运行”或“颤音”。不同位置的停顿诱导大鼠编码不同的规则为基础的代表性的模式。结果表明，在适当的条件下，大鼠可能编码的正式结构的表示，当他们学习有组织的反应模式。
Two studies used a stimulus tracking paradigm to test whether rats are sensitive to the rule-based formal properties of structured serial patterns. Hooded rats tracked 16-element patterns of flashing lights by pressing levers under an array of 6 indicator lights. In Experiment 1 rats tracked a pattern similar to one previously used with human subjects and yielded remarkably similar results. More errors and response omissions occurred at boundaries of structural "chunks" than within chunks, and errors often reflected anticipation of the next chunk or extrapolation of the preceding chunk. In Experiment 2, temporal "phrasing" cues encouraged different groups to encode a pattern as a series of either "runs" or "trills". Differential placement of pauses induced rats to encode different rule-based representations of the pattern. Results indicate that under appropriate conditions rats may encode a representation of formal structure when they learn organized response patterns.
