Kind people catch yawns

Boing Boing, this morning, has an link to an interesting story in Nature. This story reports that kind people are more likely to "catch" a yawn from someone else. Here is a quote from the story:

Those impervious to the infection also struggle to put themselves in other people's shoes, psychological tests showed. For example, they might be less likely to recognize that a social faux pas or insult could cause someone else offence. Identifying with another's state of mind while they yawn may trigger an unconscious impersonation, the team suggests. The findings might also explain why schizophrenics, who have particular difficulty in doing this, rarely catch yawns.
