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

项目摘要/摘要 拟议项目的主要目标是更好地了解剧集的发展和能力 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，并研究 能力随着年龄的变化而变化，并确定EFT过程的神经关联。在《目标2》中，我会 使用一种新的内隐EFT任务来研究早期EFT的发育起源和神经相关性。 24个月大的婴儿。在这两个目标中，将在儿童和婴儿完成发作的同时收集脑电 未来的思考任务。拟议的项目将是第一个检查EFT能力的项目，第一个检查EFT能力的项目 EFT在婴儿期的发育起源，并首次研究EFT在婴儿期的神经特征 和童年早期。我们预测，EFT的能力将随着发展而增加。我们还预测，婴儿 (18-24个月)将显示出隐含测量(前瞻性)EFT能力的证据。最后，我们期待 成人在EFT过程中活跃的类似神经区域(额叶和颞叶)在儿童中也会活跃 这些区域之间的脑电连贯性(功能连通性)会随着年龄和年龄的增加而增加 EFT容量增加。

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.
