If, in a group discussion, all members are speaking but no one is listening to others, which communication skill is weak?

Listening skill

A productive group discussion requires both speaking and attentive listening. Since members are able to speak but fail to attend to one another, the main weakness is listening. Without listening, participants cannot understand points, respond appropriately, build on ideas, or avoid unnecessary repetition.
