BEHAVIORAL AND NEURAL RESPONSES TO FACES AND EXPRESSIONS IN NONHUMAN PRIMATES

这个子项目是利用资源的许多研究子项目之一 由NIH/NCRR资助的中心拨款提供。次级项目的主要支助 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 表示子项目使用的中心基础设施的估计数量， NCRR赠款不直接向子项目或子项目工作人员提供资金。 这是该补助金的第二年报告。我们已经在头两年完成了几个目标，包括运行PCA来检查雄性和雌性黑猩猩和恒河猴面部特征的差异。这涉及到150多张面部合成图的准备，这些合成图是特定个体的10张或更多张照片的平均值，用于进行PCA分析。我们还研究了黑猩猩和猴子如何感知这些面部特征，探索使用人脸空间模型的歧视。我们还准备了面部分类任务的第一部分，并准备在第三年年初运行第二部分。 我们还收到了补充资金，用于购买与这些目标有关的一些新设备，并将在第三年实施这些新方法。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. This is the second year report for this grant. We have completed several of the aims in the first 2 years, including running PCA to examine the variance in facial features in male and female chimpanzees and rhesus monkeys. This involved the preparation of over 150 facial composites, averages of 10 or more individual photographs of specific individuals to run through the PCA analysis. We have also examined how the chimpanzees and monkeys perceive these facial features by exploring discrimination using a face space model. We have also prepared the first component of the facial categorization task and are poised to run the second component early in the 3rd year. We have also received supplemental funds to purchase some new equipment related to these aims and will work in the third year to implement these new methods.
