Physiological Barrier:
Information overload can be categorized as a physiological barrier to communication. This occurs when an individual is exposed to an excessive amount of information that surpasses their cognitive abilities to process and comprehend it effectively.

Effects of Information Overload:
- When individuals are bombarded with too much information, they may experience cognitive strain, leading to difficulty in understanding, retaining, and recalling the information.
- This can result in decreased attention span, reduced ability to make decisions, and impaired critical thinking skills.
- Information overload can also lead to stress, anxiety, and feelings of being overwhelmed, affecting the overall communication process.

Impacts on Communication:
- In a communication setting, information overload can hinder the sender's ability to convey their message clearly and concisely, as the receiver may struggle to process the overwhelming amount of information.
- On the receiving end, individuals may struggle to filter out irrelevant information, leading to misunderstandings, misinterpretations, and communication breakdowns.
- This barrier can impede effective communication and hinder the exchange of ideas, opinions, and feedback between individuals or groups.

Strategies to Overcome Information Overload:
- Prioritize information based on relevance and importance.
- Use tools such as summaries, bullet points, and visuals to present information more effectively.
- Practice active listening and ask clarifying questions to ensure mutual understanding.
- Take breaks, practice mindfulness, and manage distractions to improve focus and concentration.
In conclusion, addressing information overload as a physiological barrier to communication is essential in enhancing the quality and effectiveness of interpersonal interactions and organizational communication processes.
