Interpersonal communication, I remember this course. Did you study mass communication?
In the aspect of lack of interpersonal communication among the students of nowadays, it is due to large numbers of students in a class. During the old days we had fewer students in class, so which made it easier for everyone to know each other.
Secondly, as a result of insecurity every student is just trying to protect themselves by not getting too close to strangers because you don't know who is who.
Yeah, I studied that. Although we call it Communication Arts.
Apart from the crowd, although that is also a factor but I know departments that promote interpersonal communication and it's really effective and you can feel that sense of familiarity and collaboration.
