Final answer:
Bracketing discursive exchanges is the practice of setting aside personal biases to objectively engage in discussions about visual rhetoric.
Step-by-step explanation:
Bracketing discursive exchanges refers to setting aside personal biases when engaging in critical discourse, particularly about visual rhetoric. When analyzing visual elements and their rhetorical strategies, it is crucial to approach the discussion objectively, putting one's own preconceptions on hold to fairly assess another's perspective or the artifact's message. This allows for a more analytical and less biased discussion about visual elements like arrangement, color, and symbol, as well as the strategies used by artists to elicit responses. The concept of bracketing is integral when reflecting on and analyzing images, which in turn helps one to communicate about such images more effectively.
