The Effects of Interruptions on Conversational Behavior

There's not very good evidence of any particular biological effects other than that of hormones and particularly aggressive behaviors. Whether this is a result of biological differences or socialization is not easy to say. There seems to be a preference for girls to socialize in smaller groups, whereas men tend tosocialize in larger groups. And it may be the case that larger group size contributes to these sorts of behaviors in men so more likely to interrupt.
