"While doing so, they were filmed using 14 high-frequency video cameras, so all their movements were captured from many different angles. The resulting videos were then analyzed using advanced AI-based software to investigate various aspects of movements during hugging, such as the duration of the hug or how different body parts of the hugging volunteers (such as knees or feet) were positioned to each other. In addition, the volunteers also answered a few questionnaires about their personality and other aspects."
"Hugs can happen in sad situations (such as in hugging someone who is crying to make them feel better), happy situations (such as hugging someone who has a birthday), or neutral situations (such as hugging someone as a greeting). Besides the emotional situation the hugging people are in, their relationship can also affect the hug. For example, you would expect romantic partners and platonic friends to hug differently. Surprisingly, up to now, no psychological study has investigated how relationship status affects hugging."
Romantic partners hugged substantially longer than platonic friends, with friends averaging under three seconds and couples over seven seconds. Sixty volunteers, both friends and romantic partners, repeatedly approached and hugged while being filmed from multiple angles by 14 high-frequency video cameras. Advanced AI-based software analyzed hug duration and body-part positioning, including knees and feet. Participants completed questionnaires about personality and other aspects. Personality factors strongly affected movement patterns during hugging. Hugs occur across sad, happy, and neutral contexts, and relationship status is a key determinant of hug duration and interactive movement dynamics.
