Cognitive Mapping

Cognitive mapping is a term used to describe the mental process by which humans and animals acquire, code, store, recall, and decode information about their spatial environment. This concept, first proposed by psychologist Edward Tolman in the 1940s, revolutionized the understanding of navigation and spatial awareness. Tolman suggested that individuals create internal maps that help them navigate their surroundings efficiently.

Recent research indicates that cognitive mapping is more complex than initially thought. Neuroscientists have discovered that the hippocampus, a region of the brain associated with memory, plays a crucial role in this process. Studies involving brain imaging have shown that when people navigate through unfamiliar environments, the hippocampus becomes highly active. This suggests that cognitive mapping is not just a mental representation but also involves distinct neural pathways.

Moreover, cognitive maps are not static; they evolve with new experiences and information. For instance, if you take a different route to work, your brain updates the existing map to include this new pathway. This dynamic nature of cognitive mapping underscores its importance in learning and adaptation. Despite these advances, many questions remain about the precise mechanisms governing cognitive maps and how they vary across species.

题干翻译:第三段的目的是什么? 定位:需梳理第三段的核心内容,并结合前文(尤其是第一、二段)的逻辑关系,判断其写作目的。 选项分析: A 选项(It explains an additional feature of cognitive mapping,它解释了认知地图的一个额外特征):该选项与第三段的核心内容完全匹配,“额外特征” 即指前文未提及的 “动态演变” 属性,符合其写作目的,是正确答案。 B 选项(It provides evidence contradicting the information presented in the passage,它提供了与文章中所呈现信息相矛盾的证据):第三段内容是对认知地图特征的补充,与前文(如认知地图的复杂性、海马体的作用)无任何矛盾,排除。 C 选项(It concludes the passage by stating that cognitive mapping is now well studied and understood,它以 “认知地图现已被充分研究和理解” 为结论总结全文):第三段结尾明确提到 “许多关于认知地图的精确机制及跨物种差异的问题仍未解决”,与 “充分研究和理解” 相悖,且该段并非全文总结,排除。 D 选项(It describes examples illustrating the numerous features discussed in paragraph 2,它通过例子说明第二段中讨论的众多特征):第二段的核心是 “认知地图的复杂性” 和 “海马体的关键作用”,而第三段的例子是为了说明自身提出的 “动态特征”,与第二段的内容无关,排除。
