PsPM-HRM_IAPS dataset ====================== Repository Version: 2019.03.11 This dataset includes skin conductance response (SCR), electrocardiogram (ECG) and respiration measurements for each of 23 healthy unmedicated participants (10 males and 13 females aged 22.6 +/- 3.9 years, age is misprinted in Paulus et al. 2016) in response to the 16 most arousing negative, the 16 most arousing positive (excluding explicit nude), and the 16 least arousing neutral IAPS pictures, presented for 1 s each. ITI was selected randomly on each trial from 43 s, 45 s or 47 s. -------------------------------------------------------------------------------- This repository is curated by the PsPM team, pspm.sourceforge.net -------------------------------------------------------------------------------- Dataset is described and used in following references: - Philipp C.
