Physiological Responses to Emotional Video Stimuli: ECG, EDA, and Temperature Data

Fig. 1. Example ECG waveform from one participant during a single video clip (AI2 channel). This trace is shown for illustrative purposes to show the signal format and typical morphology and is not an aggregate statistic across participants.

Fig. 2. Example EDA signal from one participant during a single video clip (AI3 channel). This trace is provided as an illustrative example of the recorded signal and is not an aggregate statistic across participants.

Fig. 3. Example skin temperature signal from one participant during a single video clip (AI4 channel). This trace is shown as an illustrative example of the recorded data and is not an aggregate statistic across participants.

Fig. 6. Mobile application (BitalinoScientiSST) interface used during data acquisition. (a) The main acquisition screen is used to start and stop recording after the participant ID is entered. (b) The Bluetooth device discovery and pairing screen is used to connect the BITalino device. (c) New-segment action used immediately before each video stimulus to split the session into stimulus-aligned recordings. (d) Example of the acquisition screen after creating a new segment for the next stimulus. Pressing New creates a new output file bitalino_n.txt (n = 1 to 18), with one file per video clip, matching the file organisation described in the Data Description section.
