AN EXAMINATION OF THE EVOLUTIONARY SPECIALIZATIONS FOR AUDITORY MEMORY

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 人类使用包括海马体和周围脑回在内的成熟的神经解剖学基质形成强大的长期记忆。尽管猴子对视觉信息有一个熟练的长期记忆系统，依赖于类似的神经解剖区域，但很少有证据表明猴子能够在听觉模式中形成长期记忆。这是一个令人困惑的发现，并提出了一种可能性，即长期听觉记忆可能是人类特有的，并对语言的进化有一些功能性影响。 该项目的目的是测试黑猩猩的长期听觉记忆任务，作为确定听觉MTS技能进化的关键步骤，即该技能是否是类人猿独有的，或者特别是人类。 受试者接受训练，以执行听觉s/d的歧视任务，但从来没有达到所需的标准，在赠款期间。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Humans form robust long-term memories using well-established neuroanatomical substrates including the hippocampus and surrounding gyri. Despite having a proficient long-term memory system for visual information that relies on similar neuroanatomical regions, there is little evidence that monkeys are able to form long-term memories in the auditory modality. This is a perplexing finding and raises the possibility that long-term auditory memories may be specific to humans and have some functional consequence for the evolution of language. The purpose of this project is to test a chimpanzee on a long-term auditory memory task as a crucial step in determining the evolution of auditory MTS skills, i.e. whether the skill is unique to Hominoids, or specifically human. Subjects were trained to perform an auditory s/d discrimination task but never reached the required criterion in the grant period.
