👉 Viewer human experiments (VHX) are a type of psychological research where participants are subjected to non-invasive, interactive tests designed to investigate their responses and attitudes towards various stimuli or scenarios presented by an observer or experimenter remotely. These studies typically use video conferencing platforms to create the illusion of real-time interaction between researchers and subjects, allowing for controlled experiments on topics like persuasion, decision making, and social influence without physically involving participants in potentially sensitive or risky situations.
