fNIRS Recording of Prefrontal Cortex during Turkish Relative Clause Processing

The hemodynamic activity of fourteen subjects was collected via a 22-channel fNIRS system with a sampling rate of 7.8125 Hz while the subjects were performing a relative clause processing task in Turkish. The total stimuli consisted of 24 sentence-and-question pairs. Half of the sentences contained a subject-relative clause, while the other half contained an object-relative clause. The sentences were shown on a screen for 4 seconds, followed by the presentation of a Yes/No question about the sentence for 3 seconds, during which the subjects must respond via key press. The experiment was prepared in Pychopy 3.0.6 and key responses were also collected via Psychopy There was a random inter-stimulus interval within the range of 7-10 seconds. The fNIRS data provided were not preprocessed. The original output of the recording system was '.nirs', but the data were converted, without any preprocessing, into '.SNIRF', which is currently suggested as the standard data format by the fNIRS society. The recording (i.e., raw data) of one subject (Subject #6) was damaged, therefore excluded from the dataset. Furthermore, we provided one '.xlsx' file for each of the following data: response accuracy, reaction time, stimuli condition, and event timestamps. Further explanation of each file can be found In README files.

本数据集采集了14名被试在执行土耳其语关系从句加工任务时的血流动力学活动，数据通过22通道功能近红外光谱（functional near-infrared spectroscopy, fNIRS）系统采集，采样率为7.8125 Hz。总刺激材料包含24组句-问对，其中半数句子采用主语关系从句结构，剩余半数采用宾语关系从句结构。实验流程为：句子呈现在屏幕上，时长4秒，随后呈现针对该句子的是非问句，时长3秒，被试需在此期间通过按键做出反应。实验范式基于PsychoPy 3.0.6编制，按键反应数据同样通过PsychoPy采集。刺激间间隔为随机时长，范围介于7至10秒之间。本次提供的fNIRS数据未经过预处理，录制系统的原始输出格式为.nirs，但未经过任何预处理步骤，已将其转换为当前功能近红外光谱学会推荐的标准数据格式.SNIRF。一名被试（被试#6）的录制数据（即原始数据）受损，因此已从数据集中剔除。此外，我们为以下四类数据分别提供了.xlsx文件：反应准确率、反应时、刺激条件以及事件时间戳。各文件的详细说明可参阅README文件。
