Which of the following is NOT considered an internal barrier to effective communication?

Temperature is not considered an internal barrier to effective communication because it is an external factor that affects the environment in which communication occurs. Internal barriers are those that originate within the individual and can impact how messages are sent, received, and interpreted.

Noise, perception, and emotion are all internal barriers because they stem from within an individual. Noise refers to distractions in the mind or emotional turmoil that can interfere with clarity. Perception relates to how individuals interpret messages based on their own experiences and biases, which can lead to misunderstandings. Emotion influences how a person communicates and how messages are received; strong emotions can distort the meaning of the message or hinder open dialogue.

In contrast, temperature—though it can affect comfort and concentration levels—is NOT a mental or emotional barrier, and thus does not fall under the category of internal barriers to effective communication. This distinction clarifies why temperature is the correct choice in this scenario.
