Humans and animals have to balance the need for exploring new options with exploiting known options that yield good outcomes. This tradeoff is known as the explore-exploit dilemma. To better understand the neural mechanisms underlying how humans and animals address the explore-exploit dilemma, a good animal behavioral model is critical. Most previous rodents explore-exploit studies used ethologically unrealistic operant boxes and reversal learning paradigms in which the decision to abandon a bad option is confounded by the need for exploring a novel option for information collection, making it difficult to separate different drives and heuristics for exploration. In this study, we investigated how rodents make explore-exploit decisions using a spatial navigation horizon task (Wilson et al., 2014) adapted to rats to address the above limitations. We compared the rats' performance to that of humans using identical measures. We showed that rats use prior information to effectively guide exploration. In addition, rats use information-driven directed exploration like humans, but the extent to which they explore has the opposite dependance on time horizon than humans. Moreover, we found that free choices and guided choices have different influences on exploration in rodents, a finding that has not yet been tested in humans. This study reveals that the explore-exploit spatial behavior of rats is more complex than previously thought. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

时间范围和引导选择对啮齿动物探索-利用决策的影响。

人类和动物必须在探索新选择的需求与利用产生良好结果的已知选择之间取得平衡。这种权衡被称为探索-利用困境。为了更好地理解人类和动物如何解决探索-利用困境的神经机制,良好的动物行为模型至关重要。大多数以前的啮齿动物探索-利用研究都使用了行为学上不切实际的操作盒和逆向学习范式,在这些范式中,放弃错误选择的决定被探索信息收集的新选择的需要所混淆,使得难以分离不同的驱动和启发式探索. 在这项研究中,我们调查了啮齿动物如何使用空间导航地平线任务(Wilson 等人,2014 年)做出探索-利用决策,该任务适用于老鼠以解决上述限制。我们使用相同的措施将老鼠的表现与人类的表现进行了比较。我们表明老鼠使用先验信息来有效地指导探索。此外,老鼠像人类一样使用信息驱动的定向探索,但它们探索的程度对时间范围的依赖程度与人类相反。此外,我们发现自由选择和引导选择对啮齿动物的探索有不同的影响,这一发现尚未在人类身上进行过测试。这项研究表明,老鼠的探索-利用空间行为比以前认为的要复杂。(PsycInfo 数据库记录 (c) 2023 APA,保留所有权利)。老鼠像人类一样使用信息驱动的定向探索,但它们探索的程度对时间范围的依赖与人类相反。此外,我们发现自由选择和引导选择对啮齿动物的探索有不同的影响,这一发现尚未在人类身上进行过测试。这项研究表明,老鼠的探索-利用空间行为比以前认为的要复杂。(PsycInfo 数据库记录 (c) 2023 APA,保留所有权利)。老鼠像人类一样使用信息驱动的定向探索,但它们探索的程度对时间范围的依赖与人类相反。此外,我们发现自由选择和引导选择对啮齿动物的探索有不同的影响,这一发现尚未在人类身上进行过测试。这项研究表明,老鼠的探索-利用空间行为比以前认为的要复杂。(PsycInfo 数据库记录 (c) 2023 APA,保留所有权利)。这项研究表明,老鼠的探索-利用空间行为比以前认为的要复杂。(PsycInfo 数据库记录 (c) 2023 APA,保留所有权利)。这项研究表明,老鼠的探索-利用空间行为比以前认为的要复杂。(PsycInfo 数据库记录 (c) 2023 APA,保留所有权利)。
