Which approach is used to understand communication by studying the context of the content?

The correct answer is textual analysis because this approach focuses on understanding communication through the examination of texts, which may include various forms of written or spoken communication. Textual analysis delves into the meaning behind the content, considering elements such as language, structure, and symbolism within the context in which it is produced. This allows for a deeper comprehension of the messages being conveyed and how they relate to broader social and cultural frameworks.

In contrast, content analysis primarily quantifies and analyzes the specific content of communication, looking at patterns and frequency without necessarily exploring the contextual implications. Cultural communication emphasizes the influence of culture on communication practices, examining how cultural factors shape the way messages are produced and interpreted. The critical approach involves evaluating and critiquing the power dynamics and societal issues related to communication but does not specifically focus on the content context in the same way textual analysis does.
