Session 1: Screening | ||
|---|---|---|
Procedure | Time (min.) | Description |
Introduction to experiment | 10 | We provided an overview of the experiment, including purpose of the study and experimental procedures. |
Informed consent form | 10 | The participant read the consent form, which included information on the study’s aims and procedures |
Scripts selection | 30 | The participant selected the scripts for five emotion classes, the scripts that elicited the strongest emotional response |
Preliminary experiment | 30 | The participant was asked to practice the experiment paradigm with a few scripts to ensure their understanding of the task |
Feedback | 5 | Participants were asked to provide feedback regarding their emotional response, or any uncomportable feelings |
Session 2: Recording | ||
|---|---|---|
Pre-experiment assessment | 5 | Prior to the experiment, the participant’s condition was evaluated |
Calibrating equipment | 5 | We placed a computer screen, camera, and microphone in optimal proximity to the participant |
EEG setting | 20 | We put conductive gel to electrodes and examined the quality of the brain signal measurement |
Baseline recording | 10 | The participant had a brief practice session to confirm their readiness for the experiment |
Data collection | 100 | During the main experiment, a total of 200 interactions were conducted while recording multimodal EEG+audiovisual data |
