"Emotional barriers" are emotional factors that impede a speaker's ability to deliver a clear message or a receiver's ability to hear a message effectively. Common emotions, such as anger, love, joy, frustration, disappointment and sadness can all create emotional barriers that negatively affect communication.
In some cases, a person's emotions may prevent him from discussing certain topics. A person scared of commitment may avoid talking intimately with a partner. An angry person may struggle to communicate an articulate message because anger clouds rational thoughts and words. A person who is sad may not listen well to the advice of a close friend.
