A simultaneous EEG-fNIRS dataset of the visual cognitive motivation study in healthy adults

Motivation has various positive influences on human activity and has been the topic of interest in the educational psychology field. To gain an in-depth understanding and insights into motivation, we must learn from the related brain activity during motivation events. Brain activity signals can be acquired with various methods. Each modality has its own strengths and weaknesses. We simultaneously measured Electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) at shared locations. Using simultaneous EEG (high temporal resolution but low spatial resolution) and fNIRS (high spatial resolution but relatively low temporal resolution compared to EEG), we can obtain both electrophysiological and hemodynamical brain activity data with high temporal and spatial resolution at the same time and locations. Hence, the motivation can be studied in a more complete picture than either of the individual modalities can offer. This dataset includes the simultaneous EEG-fNIRS data of 16 healthy participants measured while performing the cognitive motivation task. The cognitive motivation task is separated into two parts: attention and decision. Each visual stimulus, which is a randomly selected indoor/outdoor scene, was shown to the participant for 3 seconds during the attention period and then disappeared. The participants are required to decide whether or not they want to remember the scene stimulus they have seen within 9 seconds. There was no constraint or influence on their decisions. The EEG-fNIRS data were acquired during this whole cognitive experiment for 250 scene stimuli of each participant. The effect of their motivation was confirmed by the recognition test; the participants were tested with 500 mixed stimuli between 250 previously seen stimuli in the cognitive experiment and the new additional stimuli to test whether they could recognize the scene in the cognitive experiment or not. This dataset provides an opportunity for understanding and analyzing the process of attention and decision during the motivated brain state as well as the motivation and its effect on the recognition result afterward.

动机对人类活动具有多维度积极影响，长期以来都是教育心理学领域的重点研究议题。若要深入理解动机的本质与内在机制，必须探究动机触发时的相关脑活动。脑活动信号可通过多种技术手段采集，各类模态各有优劣。本研究在共定位区域同步采集脑电图（Electroencephalogram, EEG）与功能性近红外光谱（functional near-infrared spectroscopy, fNIRS）数据：脑电图具备高时间分辨率但空间分辨率有限，而功能性近红外光谱则空间分辨率优异，但时间分辨率相对弱于脑电图。通过结合二者，我们可在同一位置同步获取电生理与血液动力学的脑活动数据，实现时空分辨率的协同提升。因此，本研究能够比单一模态研究更全面地刻画动机相关的脑机制。
本数据集包含16名健康成年受试者完成认知动机任务时采集的同步EEG-fNIRS数据。该认知动机任务分为注意力与决策两个阶段：注意力阶段中，随机选取的室内/室外场景视觉刺激将呈献给受试者，持续3秒后消失；受试者需在9秒内判断是否希望记住该场景刺激，且其决策不受任何约束或干扰。本次认知实验全程采集EEG-fNIRS数据，每位受试者对应250个场景刺激。受试者的动机效应通过再认测试验证：测试包含500个混合刺激，其中250个为认知实验中已呈现的旧刺激，剩余250个为新增的新刺激，用于检测受试者能否再认实验中出现过的场景。
本数据集为探究动机脑状态下的注意力与决策过程，以及动机对后续再认结果的影响提供了优质研究载体。
