Replication Data for: The relation between auditory cognitive control and vagally-mediated heart rate variability in and outside the lab: Differential effects of circadian rhythm?

This dataset consists of vagally mediated heart rate variability (HRV; Root Mean Square of Successive Differences) and auditory cognitive control using the Bergen Dichotic Listening (BDL) task, including the forced-left (FL) and forced-right (FR) conditions of the BDL. Resting HRV was recorded, followed by ambulatory HRV monitoring at different times across the day to evaluate the impact of circadian rhythms. The dataset provides a basis to analyze the potential of HRV as a biomarker in different cognitive conditions and during varying times of day. The data encompass 64 healthy participants (35 women) who undertook BDL tasks in a laboratory environment. --------------------------------------------------- Overview and Description of Variables --------------------------------------------------- ID: The identification numbers are randomly generated (not original) BMI: Body Mass Index Age Sex/Gender: 1 = Women, 2 = Men FR_RE_1: Accuracy score from the Forced Right (Forced Right Right Ear) dichotic listening in laboratory (Forced-Right condition (DL)) FL_LE_1: Accuracy score from the Forced Left (Forced Left Left Ear) dichotic listening in laboratory (Forced-Left condition (DL)) FR_RE_2: Forced-Right condition (DL) Afternoon FL_LE_2: Forced-Left condition (DL) Afternoon FR_RE_3: Forced-Right condition (DL) Night FL_LE_3: Forced-Left condition (DL) Night FR_RE_4: Forced-Right condition (DL) Morning FL_LE_4: Forced-Left condition (DL) Morning ECG_HR: mean Heart Rate from ECG in laboratory ECG_RR: mean R to R duration in ms.

本数据集包含迷走神经介导的心率变异性（heart rate variability, HRV；逐次心跳间期差值均方根，Root Mean Square of Successive Differences），以及采用卑尔根双耳分听（Bergen Dichotic Listening, BDL）任务开展的听觉认知控制实验数据，涵盖该任务的强制左耳（forced-left, FL）与强制右耳（forced-right, FR）两种实验条件。研究首先记录受试者静息状态下的HRV数据，随后在一日内的不同时段开展动态HRV监测，以评估昼夜节律对心率变异性的影响。本数据集可为分析心率变异性作为不同认知状态下以及一日内不同时段的生物标志物的潜力提供数据支撑。本次数据集共纳入64名健康受试者（其中女性35名），所有受试者均在实验室环境中完成了BDL任务。
