非人类动物，像人类一样，对序列元素的结构似乎很敏感，甚至可能当该结构与非相邻元素相关时也是如此。在本研究中，我们考察了分组、规则学习和项目记忆在大鼠学习由两个交错子模式组成的序列模式时的作用。在一个组中，第一个交错子模式是一个形式上简单的序列，而在另外两个组中，第一个子模式是一个形式上更复杂的序列，分别包含2个或4个违反元素。在所有组中，遇到的第二个交错子模式在形式上都很简单。该研究的证据表明，大鼠将它们的交错模式分成组件子模式，也就是说，它们在认知上将模式元素分类，形成基于非相邻结构关系的块，这些关系可以被表征为规则。他们还通过传统的辨别学习来学习项目间关联，即使用相邻元素作为序列中后面事件的复合或结构线索。因此，有证据表明，大鼠同时使用分块、规则学习和项目间关联学习来掌握这些复杂的模式。(c) 2005爱思唯尔公司版权所有。
Nonhuman animals, like humans, appear sensitive to the structure of the elements of sequences, perhaps even when the structure relates nonadjacent elements. In the present study, we examined the contribution of chunking, rule learning, and item memory when rats learned serial patterns composed of two interleaved subpatterns. In one group, the first interleaved subpattern was a formally simple sequence, whereas in two other groups the first subpattern was formally more complex, containing 2 or 4 violation elements, respectively. In all groups, the second interleaved subpattern encountered was formally simple. Evidence from the Study suggests that rats chunked their interleaved patterns into component subpatterns, that is, they cognitively sorted pattern elements to form chunks based on nonadjacent structural relationships that can be characterized as rules. They also learned interitem associations via traditional discrimination learning to use adjacent elements as compound or configural cues for later events in the sequence. Thus, the evidence Suggests that rats used chunking, rule learning, and interitem association learning concurrently to master these complex patterns. (c) 2005 Elsevier Inc. All rights reserved.
