1. Effective communication can be hindered by various barriers in the communication process that can distort messages. Physical, semantic, organizational, psychological, personal, cultural and gender barriers were discussed.
2. Physical barriers include noise, distance, information overload, and environmental factors that can disrupt clear transmission of messages. Semantic barriers occur when senders and receivers assign different meanings to words. Organizational barriers involve issues like status differences, policies and complex structures.
3. Psychological barriers relate to mental states like lack of attention, distrust, and emotions that influence understanding. Personal barriers are individual factors that affect one's ability to communicate. Cultural and gender differences can also introduce barriers if they are not understood by all parties.
