Psychologist Dennis Barr discusses bullying and osctracism.
The initial research on bullying focused a lot on what I think people think of as more the teasing and the physical aggression that can occur. And this issue that the case raises around relational aggression really didn't come to the fore until the last 15 years or so.
Over the last 15 years, there have been many books written and articles written about this kind of aggression, or this kind of bullying, that can occur in relationships, where it involves not necessarily direct action towards the victim, but indirect action that can have just as strong an effect. So the shunning, or the ostracizing, the not paying attention to, the leaving out, can be such a powerful and painful experience and is now recognized as bullying and called as such. Whereas in the past, it really hasn't gotten that kind of attention.
