Looking for a romantic relationship? Then you'll know how important that first date can be. When falling in love, what makes us attracted to some people, and not to others? The answer will be surprising to most of us – but it wasn't to the team of researchers led by Dr. Shir Atzil of the Department of Psychology at the Hebrew University in Jerusalem.
"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. The study was based on a speed-date experiment consisting of forty-six dates. Each date lasted 5 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, 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. This research was recently published in Scientific Reports.

Intriguingly, 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.
The experimental setting. A man and a woman meet for a speed date while their behavior and physiology are being recorded, providing 1200 physiological data points (sampled at 4 Hz) and 3000 behavioral data points per date for each subject (sampled at 10 Hz). The room design, as well as the ambulatory recording equipment, enabled participants to freely interact, for an ecologically-valid estimation of bio-behavioral measures, naturally occurring during a romantic date. After the date, participants rate their romantic interest and sexual attraction to the partner. We measured the association between physiological synchrony and behavioral attunement during a date, and the romantic and sexual ratings after the date. (CREDIT: The Hebrew University of Jerusalem)
"Our research, " said Atzil, "demonstrates that behavioral and physiological synchrony can be a useful mechanism to attract a romantic partner. 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 Atzil is planning to investigate.
