Step 1: Understand the question:
Psychological barriers are blocks in communication that arise from the mental state and emotions of the sender or the receiver.
Any four are needed. I will give four, each with a short explanation.
Step 2: Premature evaluation:
Some people form a judgment before they hear the full message. They decide its meaning early.
Such an attitude blocks the true meaning and results in a wrong response.
Step 3: Lack of attention:
The receiver may be busy with other thoughts and does not listen with care. His mind is preoccupied.
He then misses parts of the message, and it is not understood fully.
Step 4: Loss by transmission and poor retention:
When a message passes through many people in a chain, each one drops or changes some part of it. Much of it is lost.
Also, people do not always remember what they hear. Poor retention reduces the effect of the message.
Step 5: Distrust:
If the sender and the receiver do not trust each other, the message is not taken in its real sense.
The receiver doubts the sender and may look for hidden meaning, so the communication fails.
Final Answer:
Four psychological barriers are premature evaluation, lack of attention, loss by transmission and poor retention, and distrust.
