Development of Episodic Future Thinking: Limits, Flexibility, and Neural Correlates

项目总结/摘要 拟议项目的主要目标是更好地了解情节的发展和能力， 未来思维（EFT）在目标1中，我将量化2岁、3岁和4岁儿童的EFT能力， 能力的变化，作为年龄的结果，并确定EFT过程的神经相关。在目标2中，我将 研究早期EFT的发展起源和神经相关性，使用一种新的内隐EFT任务， 24个月大的婴儿。在这两个目的中，将在儿童和婴儿完成发作性检查时收集EEG。 未来的思考任务拟议的项目将是第一个审查电子资金转移的能力，第一个审查 婴儿期EFT的发展起源，以及第一个研究婴儿期EFT的神经特征 和幼儿期。我们预测EFT容量将随着发展而增加。我们还预测婴儿 （18-24个月）将显示出隐性测量（预期期待）EFT能力的证据。最后，我们期待 成人在EFT期间活跃的类似神经区域（额叶和颞叶）在儿童中也会活跃。 这些区域之间的EEG相干性（功能连接）将随着年龄的增长而增加， EFT能力增强。

PROJECT SUMMARY/ABSTRACT The primary goal of the proposed project is to better understand the development and capacity of episodic future thinking (EFT). In Aim 1, I will quantify the capacity of EFT in 2-, 3-, and 4-year-olds and examine how capacity changes as a result of age, and identify the neural correlates of EFT processes. In Aim 2, I will examine the developmental origins and neural correlates of early EFT using a novel implicit EFT task with 18- 24-month-old infants. In both Aims, EEG will be collected while children and infants complete the episodic future thinking tasks. The proposed project will be the first to examine the capacity of EFT, the first to examine the developmental origins of EFT in infancy, and the first to examine the neural signatures of EFT in infancy and early childhood. We predict that EFT capacity will increase with development. We also predict that infants (18-24 months) will show evidence of implicitly measured (anticipatory looking) EFT ability. Finally, we expect that similar neural regions (frontal and temporal) that are active during EFT in adults will be active in children and infants, and that EEG coherence (functional connectivity) between these regions will increase as age and EFT capacity increases.
