Semantic barriers to communication include badly expressed messages, symbols with different meanings, and a lack of common language or poor vocabulary. Psychological barriers arise from motives, emotions, social values, and perceptions, such as premature evaluation, lack of attention, and distrust. Organizational barriers in the workplace include rules and regulations, lack of staff meetings, status differences, and hierarchical relationships. Physical barriers to communication can occur due to distance, noise, incomplete information, and overloaded information from environmental and natural conditions.
