Hello. everyone.
 
I am a graduate student studying new communication technologies. I like to ask questions about some terms from some articles I read. 
 
1. collective cognition of the society
 
2. cognitive  background noise
 
 
 
If any one can give some ideas or  recommend some references about them, it will be great help to me.
 
 
Sincerely
 
Jenghoon Lee
