Always on My Mind When they were together, younger partners were more accurate than older ones at knowing their partner’s emotions, but older partners were as good as younger ones when they were apart. This study used “smart phone experience sampling,” buzzing both partners simultaneously to ask how they and their partner felt. Interestingly, differences were found with age but not length of relationship—five, ten, twenty, or thirty years of togetherness did not necessarily increase empathy when apart, but men who were in their 70s were better at absent mood assessment than men in their 20s.
