What makes us attracted to some people, and not to others? What happens in the first date that makes it the beginning of a long-term relationship? The team of researchers led by Dr. Shir Atzil of the Department of Psychology at the Hebrew University in Jerusalem say they have found the answer.

  • “Connecting with a partner depends on how well we can synchronize our bodies. We specialize in studying parent-infant bonding – and we had already seen the same thing there,” she explained.

    The researchers looked at how a heterosexual couple’s physiology and behavior adapt to each other during that first encounter. Physical synchrony is an important nonverbal factor in forming and modulating communications. To foster cooperation, humans express and read intentions via explicit signals and subtle reflections of arousal visible on the face.
    Evidence is accumulating that humans synchronize these nonverbal expressions and the physiological mechanisms underlying them, potentially influencing cooperation.
    The study was based on a speed-date experiment consisting of 46 dates. Each date lasted five minutes during which the levels of physiological regulation of each partner were recorded with a band worn on the wrist. Behavioral movements, such as nodding, moving an arm, and shifting a leg were also recorded in each partner during the date.

    After the encounter, the couple assessed the romantic interest and sexual attraction they felt for each other. The study clearly showed that when couples synchronize their physiology with one another and adapt their behavioral movements to their partner during the date, they are romantically attracted to one another.
    The study also showed that the degree of synchrony affected men and women differently. Although for both genders synchrony predicted attraction, women were more sexually attracted to men who showed a high level of synchrony – “super-synchronizers”; these men were highly desirable to female partners.
    “Our research demonstrates that behavioral and physiological synchrony can be a useful mechanism to attract a romantic partner,” Atzil said.
    “However, we still don’t know whether synchrony raises attraction or does the feeling of attraction generate the motivation to synchronize?” An area of research that she is planning to investigate.
