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
