In this article we addressed the question whether rats can use distal landmarks as directional cues that are used in combination with other proximal landmark configurations. The animals were trained with an A, B, C, and D landmark configuration in the Morris pool, where B and C are the near (to platform) landmarks and A and D the far ones. We also added another more distal "directional" cue Z (a white strip attached to the black curtain surrounding the pool). Experiment 1a shows a robust detrimental effect on the time spent by the rats swimming in the platform quadrant when the location of all landmarks was "Inverted" (rotated by 180 degrees) with respect to Z. A similar detrimental effect was found when, after the inversion manipulation, the locations of the near and far landmarks were "Flipped" (B swapped with C and A with D). Rats in both Inverted and Flipped tests spent more time in the Z quadrant compared to the platform quadrant (BC). Experiment 1b provided evidence distinguishing between alternative explanations of how the directional cue Z acts in combination with the other landmarks. The results from both experiments show that Z operates differently to the standard landmarks. It can function as a beacon in its own right. It can also combine with the other landmarks to produce a high level of search performance, in a way that we hypothesize to be distinct from that described by the configural analysis often applied to multiple landmarks.

方向提示和界标配置:旋转一组界标相对于另一组界标的效果。

在本文中,我们讨论了大鼠是否可以将远侧界标用作与其他近侧界标配置结合使用的方向提示的问题。在莫里斯池中对动物进行了A,B,C和D地标配置的训练,其中B和C是近(到平台)地标,而A和D是远地标。我们还添加了另一个更远端的“定向”提示Z(白条连接到围绕游泳池的黑色窗帘上)。实验1a显示了当所有地标的位置相对于Z轴“倒置”(旋转180度)时,老鼠在平台象限内游泳所花费的时间具有强烈的有害影响。反演操作,将近地标和远地标的位置“翻转” (B与C交换,A与D交换)。与平台象限(BC)相比,在反向和翻转实验中,大鼠在Z象限中花费的时间更多。实验1b提供了区分方向性提示Z如何与其他界标一起起作用的替代解释的证据。两次实验的结果均表明Z与标准界标的运行方式不同。它本身可以充当信标。它也可以与其他地标结合使用,以产生高水平的搜索性能,我们认为这与经常应用于多个地标的配置分析所描述的方式不同。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。实验1b提供了区分方向性提示Z如何与其他界标一起起作用的替代解释的证据。两次实验的结果均表明Z与标准界标的运行方式不同。它本身可以充当信标。它也可以与其他地标结合使用,以产生高水平的搜索性能,我们认为这与经常应用于多个地标的配置分析所描述的方式不同。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。实验1b提供了区分方向性提示Z如何与其他界标一起起作用的替代解释的证据。两次实验的结果均表明Z与标准界标的运行方式不同。它本身可以充当信标。它也可以与其他地标结合使用,以产生高水平的搜索性能,我们认为这与经常应用于多个地标的配置分析所描述的方式不同。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。它也可以与其他地标结合使用,以产生高水平的搜索性能,我们认为这与经常应用于多个地标的配置分析所描述的方式不同。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。它也可以与其他地标结合使用,以产生高水平的搜索性能,我们认为这与经常应用于多个地标的配置分析所描述的方式不同。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。
