These files are the raw data files on which the results for these publications were based:Wass, S. V., Smith, C. G., Daubney, K. R., Suata, Z. M., Clackson, K., Begum, A., & Mirza, F. U. (2019). Influences of environmental stressors on autonomic function in 12‐month‐old infants: understanding early common pathways to atypical emotion regulation and cognitive performance. Journal of Child Psychology and Psychiatry, 60(12), 1323-1333.Wass, S. V., Smith, C. G., Clackson, K., Gibb, C., Eitzenberger, J., & Mirza, F. U. (2019). Parents mimic and influence their infant’s autonomic state through dynamic affective state matching. Current biology, 29(14), 2415-2422.Further details on the device used are given in these publications. The data uploaded here consist of the raw ECG data, raw accelerometer data and time files for these devices. In addition we also have GPS data, microphone recordings and video recordings, but these have not be uploaded as they contain identifiable information. If you wish to obtain these recordings, or to obtain the processed versions of the raw data uploaded here, please contact s.v.wass@uel.ac.uk. Results/accel/raw csv - these results contain the raw accelerometer data, recorded at 30Hz. The recording duration is identical to the ECG and times files (but the file lengths are different due to the different sampling frequency). Cols 2-4 show the x/y/z dimensions, and col 1 is an average of cols 2-4. The number shows the participant number, _B indicates baby and _M indicates mum. So 222_B and 222_M were recorded from an infant and mother concurrently. Results/ECG/raw csv - these results contain the raw ECG data, recorded at 250Hz. The labelling is identical to the accelerometer data. Results/times/raw csv - these results contain the timings of the recordings, recorded at 1Hz. The recording duration is identical to the accelerometer and ECG files. The format of the columns is: [phonetime clockhr clockmins clocksec day month year linecounter].Results/startstoptimes - these files contain the start and stop times of good usable data segments. First two columns are start and stop time of the good segments at 1Hz. Third and fourth columns are the same but in minutes. Before analysing the ECG or accelerometer data you should score out the sections of data before the start time and after the stop time. Results/accel/touch syncs - these files are needed to synchronise the baby and mum recordings. The first two columns are two separate estimations of the difference in seconds in recording start time between the baby and mum devices. Always Mum-Baby.
