In a Social Monologue, two children are talking together, but not coordinating the context.
The Collective (Dual or Social) Monologue involves usually two or more children playing in close proximity. They may be playing different games and they may be commenting on them and they may be even taking turns in vocalizing, but the context of their speech is not correlated between each other.
Children do it all the time when their playing, teenagers do it when they are rapping, and adults do it, especially when they have been drinking.
In the notes you can hear an example of teenagers doing it. This is a short excerpt from the TV series (one of the few worthwhile ones) called “My So Called Life.”
One teen is talking about a teacher who misused his name, and the other is talking about a girl who asked him to help her with Algebra.
NOTES: Hear a collective monologue
