Cheng (1986) trained male rats to search for food in a rectangular arena that also contained distinctive visual patterns. He found that the rats used mainly the geometric framework of the box itself to find the food and claimed that geometrical information is processed in a specialized module, which is independent of feature information. The aim of the present set of experiments was to check if the previous results with male rats and an appetitive task could be extended to an aversive task while using both male and female rats and three-dimensional landmarks. In Experiments 1 and 2, rats were trained in a rectangular-shaped pool to find a hidden platform that had a location defined in terms of two sources of information-landmarks of different salience (less salient in Experiment 1, more salient in Experiment 2) outside the pool and a particular corner of the pool. The results showed that both males and females used mainly the particular corner of the pool, supporting Cheng's suggestion. In addition, in the two experiments, what the rats learned with respect to the landmarks was negligible. Experiment 3 used a more difficult triangular pool in addition to the rectangular pool, in the absence of landmarks. The results revealed sex differences in the triangular pool but not in the easier rectangular pool. These results suggest that task difficulty is a factor when it comes to finding sex differences in rats in spatial tasks. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

导航时的几何学习:任务难度和性别差异的重要性。

Cheng (1986) 训练雄性老鼠在一个长方形的舞台上寻找食物,这个舞台也包含独特的视觉模式。他发现老鼠主要利用盒子本身的几何框架来寻找食物,并声称几何信息是在一个专门的模块中处理的,独立于特征信息。本组实验的目的是检查以前的雄性大鼠和食欲任务的结果是否可以在同时使用雄性和雌性大鼠以及三维地标的情况下扩展到厌恶性任务。在实验 1 和 2 中,大鼠在一个矩形池中接受训练,以找到一个隐藏的平台,该平台的位置由两个不同显着性的信息源定义(在实验 1 中不太显着,在实验 2) 中更突出的池外和池的特定角落。结果表明,男性和女性都主要使用游泳池的特定角落,支持郑的建议。此外,在这两个实验中,大鼠对地标的了解可以忽略不计。实验 3 在没有地标的情况下,除了矩形水池之外,还使用了更难的三角形水池。结果揭示了三角形池中的性别差异,但在较简单的矩形池中则没有。这些结果表明,任务难度是在空间任务中发现大鼠性别差异的一个因素。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。的建议。此外,在这两个实验中,大鼠对地标的了解可以忽略不计。实验 3 在没有地标的情况下,除了矩形水池之外,还使用了更困难的三角形水池。结果揭示了三角形池中的性别差异,但在较简单的矩形池中则没有。这些结果表明,任务难度是在空间任务中发现大鼠性别差异的一个因素。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。的建议。此外,在这两个实验中,大鼠对地标的了解可以忽略不计。实验 3 在没有地标的情况下,除了矩形水池之外,还使用了更困难的三角形水池。结果揭示了三角形池中的性别差异,但在较简单的矩形池中则没有。这些结果表明,任务难度是在空间任务中发现大鼠性别差异的一个因素。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。这些结果表明,任务难度是在空间任务中发现大鼠性别差异的一个因素。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。这些结果表明,任务难度是在空间任务中发现大鼠性别差异的一个因素。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。
