Human-derived noise pollution is a ubiquitous feature of many landscapes and has been shown to have a variety of negative effects on the ecology and behavior of animals. Recent research indicates that noise pollution could also affect how well animals learn to solve problems. This award examines the mechanism through which noise pollution affects animal cognition and will help determine whether animals living in noisy habitats (e.g., near highways or busy cities) can overcome the negative impacts of these noise sources on their cognitive performance. This research will provide generalizable insights about how animals respond to changing environmental conditions and will have key implications for the conservation of animal populations. With similar negative effects of noise on cognitive function also proposed for humans, better understanding this relationship will also likely have direct application to the welfare of human societies. The award will provide key infrastructure and research capability at a primarily undergraduate and minority-serving institution, leading directly to numerous opportunities for undergraduate students to gain hands-on research experiences that will help support their future careers in science, especially from groups who have traditionally been underrepresented in STEM fields. Anthropogenic noise has a number of detrimental impacts on animal physiology, behavior, populations, and communities. A recent study demonstrated further negative effects on cognitive function in one species of captive-raised songbird, but this phenomenon has been little studied and the mechanisms driving this relationship are unknown. The goal of this research is to determine whether traffic noise similarly impacts cognition in other songbird species and whether animals that regularly encounter noise pollution in their environment continue to experience the same level of reduced cognitive performance as naïve individuals. This research will expose birds to foraging tasks designed to measure a variety of aspects of animal cognition (e.g., inhibitory control, motor learning, associative learning, spatial memory, etc.) under varying road traffic noise regimes. This research will make several advances by examining how varying the type and duration of traffic noise exposure impacts cognitive performance in birds held under carefully controlled laboratory conditions, determining whether previous findings extend to wild songbird species, and establish whether noise differentially affects those animals living in wild populations that are more exposed to noise pollution. The results of this award will shed light on the mechanisms driving noise-induced cognitive inhibition, with implications for cognitive science, animal behavior, urban ecology, and conservation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

人为噪声污染是许多景观的普遍特征，并已被证明对动物的生态和行为有各种负面影响。最近的研究表明，噪音污染也会影响动物学习解决问题的能力。该奖项研究了噪音污染影响动物认知的机制，并将有助于确定生活在嘈杂栖息地的动物（例如，在高速公路或忙碌城市附近）可以克服这些噪声源对他们认知表现的负面影响。这项研究将为动物如何应对不断变化的环境条件提供可推广的见解，并将对动物种群的保护产生重要影响。由于噪音对人类认知功能的负面影响也被提出，更好地理解这种关系也可能直接应用于人类社会的福利。该奖项将提供关键的基础设施和研究能力，主要是本科生和少数民族服务机构，直接导致本科生获得实践研究经验的众多机会，这将有助于支持他们未来的科学事业，特别是从传统上在STEM领域代表性不足的群体。人为噪声对动物的生理、行为、种群和群落有许多不利影响。最近的一项研究表明，在一种人工饲养的鸣禽中，认知功能会受到进一步的负面影响，但这种现象很少被研究，驱动这种关系的机制也不清楚。这项研究的目的是确定交通噪音是否同样影响其他鸣禽物种的认知能力，以及在环境中经常遇到噪音污染的动物是否会继续经历与天真个体相同的认知能力下降水平。这项研究将使鸟类暴露于觅食任务，旨在测量动物认知的各个方面（例如，抑制控制、运动学习、联想学习、空间记忆等）在不同的道路交通噪音制度。这项研究将通过研究不同类型和持续时间的交通噪声暴露如何影响在严格控制的实验室条件下举行的鸟类的认知表现，确定以前的研究结果是否延伸到野生鸣禽物种，并确定噪声是否差异影响那些生活在野生种群中的动物，这些动物更容易受到噪声污染。该奖项的结果将揭示驱动噪声引起的认知抑制的机制，并对认知科学、动物行为、城市生态和保护产生影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
