New research suggests that common wisdom might be wrong, and that a significant percentage of long-term couples remain deeply in love.
In 2012, the psychologist Daniel O’Leary and his team at Stony Brook University in New York asked study participants this basic question: ‘How in love are you with your partner?’ Their national survey of 274 individuals married for more than a decade found that some 40 per cent said ‘very intensely in love’ (scoring seven on a seven-point scale)….
Research in neuroscience identifies the possible mechanism behind these results. In a study published in 2012, Stony Brook psychologist Bianca Acevedo and colleagues reported on 10 women and seven men married an average of 21 years and claiming to be intensely in love. The researchers showed participants facial images of their partners while scanning their brains with fMRI. The scans revealed significant activation in key reward centres of the brain – much like the patterns found in people experiencing new love, but vastly different from those in companionate relationships.
