Marriage counselor John Gottman holds that how spouses interact with each other determines marital stabilty and the likelihood of divorce. This Discovery Health Channel video shows couples undergoing assessment by the Gottman Institute at home, in their cars, in monitored conflict discussions and at 18-hour live-ins at the Institute, nicknamed the "Love Lab". The value of videotaping interactions when putting marriages back together is illustrated. Directed by Jamie Hellman and Barbara Leibovitz ; narrated by Sally Kellerman.
