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. We are investigating the development of cognitive and emotional influence over internal interval timing skills in adolescents. Interval timing refers to a person's "sense of time", that is, being able to judge how much time has elapsed and/or being able to reproduce a time interval when asked. We are seeking to determine whether timing processes are accurate in adolescents as compared to adults, as well as to determine if experimental manipulations of cognitive load and emotional valence will differentially interact with interval timing skills across development. We also plan to investigate the neural correlates of timing processes. This study will have a behavioral component and a neuroimaging component. We will use computer-based cognitive tasks as well as funtional magnetic resonance imaging (fMRI).

该子项目是利用资源的众多研究子项目之一 由 NIH/NCRR 资助的中心拨款提供。子项目的主要支持 并且子项目的主要研究者可能是由其他来源提供的， 包括其他 NIH 来源。 子项目可能列出的总成本 代表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。 我们正在研究认知和情感的发展对青少年内部间歇计时技能的影响。间隔计时是指一个人的“时间感”，即能够判断已经过去了多少时间和/或能够在被问到时重现时间间隔。我们正在寻求确定与成人相比，青少年的计时过程是否准确，以及确定认知负荷和情绪效价的实验操作是否会与整个发育过程中的间隔计时技能产生不同的相互作用。我们还计划研究计时过程的神经关联。 这项研究将包括行为部分和神经影像部分。我们将使用基于计算机的认知任务以及功能磁共振成像（fMRI）。
