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:第二段中 “crucial” 一词的意思最接近 定位:“crucial” 出现在原文第二段第二句 “Neuroscientists have discovered that the hippocampus, a region of the brain associated with memory, plays a crucial role in this process.” 中,其中 “this process” 指代前文提到的 “认知地图构建过程”。 选项分析: A 选项(significant,重要的):与语境中 “海马体对认知地图构建的关键作用” 相符,且能与后文实验证据形成逻辑呼应,是 “crucial” 的同义替换,为正确答案。 B 选项(complex,复杂的):“复杂的” 用于描述事物的结构或难度,无法体现 “作用的重要性”,与 “crucial” 的含义无关,排除。 C 选项(optional,可选的):“可选的” 表示非必需,与原文强调海马体的关键作用相悖,排除。 D 选项(rare,罕见的):“罕见的” 用于描述事物出现的频率,与 “作用的重要性” 无关,排除。
