FUNCTIONAL NEUROIMAGING OF REWARD AND TIMING PROCESSES IN ADOLESCENTS

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 我们正在调查认知和情绪对青少年内部间隔计时技能的影响的发展。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/或能够在被询问时重现一个时间间隔。我们正在寻求确定青少年的计时过程是否与成年人相比是准确的，以及确定认知负荷和情绪价值的实验性操纵是否会在整个发展过程中与间隔计时技能产生不同的交互作用。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成像部分。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)。

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. 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).
