The default network is involved in self-generated thought, a class of cognition that includes autobiographical memory, prospection, and reasoning about the mental states of others. We collected a replication sample of Spreng and Grady (J Cogn. Neurosci. 22, 1112-1123, 2010), confirming that the default network differentially supports each of these forms of self-generated thought. Here we describe this dataset of multi-echo fMRI data in 31 young adults during autobiographical remembering, imagining, and mentalizing; we also provide an additional resting-state scan for each subject. In this new sample, the findings from the original report are successfully replicated using the same analysis. Physiological measures were additionally collected and allow for interrogation of the impact of multi-echo independent components preprocessing both in task and rest. Future work on this dataset may provide insight into evoked brain response for cued self-generated thought, International Affective Picture System viewing, resting state dynamics, preprocessing procedures, and more. The dataset is accompanied by experimental code for independent behavioral data collection.
默认网络参与自我产生的思维，这是一类认知，包括自传体记忆、预测和推理他人的心理状态。我们收集了 Spreng 和 Grady（J Cogn. Neurosci. 22, 1112-1123, 2010）的复制样本，证实了默认网络可以分别支持这些自我产生思维的形式。在这里，我们描述了这组在 31 名年轻成年人中进行自传体记忆、想象和心理化时的多回波 fMRI 数据；我们还为每个被试提供了额外的静息态扫描。在这个新样本中，使用相同的分析成功复制了原始报告中的发现。此外，还收集了生理测量值，可以在任务和静息状态下询问多回波独立成分预处理的影响。对这个数据集的进一步研究可能会深入了解提示性自我产生思维、国际情感图片系统观察、静息状态动态、预处理过程等方面的诱发脑反应。该数据集还附有独立行为数据收集的实验代码。
