Abstract

A new paradigm of learning was developed through observational training in which rats repeatedly observed companion rats performing different spatial tasks. Observer animals were separately housed in small cages suspended over a water maze tank. They repeatedly observed companion actor rats performing spatial tasks differing according to the experimental requirements. After the observational training, observer animals were or not surgically hemicerebellectomized. This surgical ablation was performed to block any further acquisition of new behavioral strategies during actual performance of swimming task. When cerebellar symptomatology stabilized, observer animals were actually tested in the Morris Water Maze (MWM) task they had previously only observed. The observer rats displayed exploration abilities that closely matched the previously observed behaviors. The results obtained indicate that it is possible to learn complex behavioral strategies by observation using this new protocol. Furthermore, acquisition of the single facets that form the behavioral repertoire can be separately studied.

一种分析大鼠观察学习的新范式

通过观察性训练，大鼠反复观察同伴大鼠执行不同的空间任务，形成了一种新的学习范式。观察动物分别被安置在悬挂在水迷宫水箱上方的小笼子里。他们反复观察同伴行为大鼠根据实验要求执行不同的空间任务。观察性训练后，观察动物进行或不进行手术切除半小脑。这种手术消融是为了在实际执行游泳任务时阻止任何新的行为策略的进一步获得。当小脑症状稳定后，观察动物实际上在莫里斯水迷宫(MWM)任务中进行了测试，它们以前只观察过。观察大鼠表现出的探索能力与先前观察到的行为密切匹配。结果表明，利用该协议可以通过观察学习复杂的行为策略。此外，形成行为曲目的单个方面的习得可以单独研究。
