The study examined the frequency of laughter in couples during different conversational contexts and its ability to predict positive emotions. 69 couples participated in 6 conversations about love, sacrifice, suffering/sadness, and rated their emotions after each. The love conversation had the most laughter and highest positive emotions, while the suffering conversation had the least. Across all conversations, more laughter predicted greater positive emotions. However, within individual conversations, laughter only predicted positive emotions in the suffering conversation. So laughter is generally indicative of positive emotion but depends on the conversational context.
