What unique procedure did Kelly initially use to modify constructs?

The procedure that Kelly initially used to modify constructs involves offering "preposterous interpretations." This technique reflects Kelly's approach to understanding how individuals perceive and organize their experiences using personal constructs. By encouraging clients to frame their thoughts or experiences in an exaggerated or absurd manner, it helps to challenge existing beliefs and allows for new perspectives to emerge. This strategy is significant because it disrupts habitual thinking patterns, providing an opportunity for individuals to reevaluate their constructs and potentially make adjustments that lead to more flexible and adaptive ways of understanding their experiences.

The other options, while they may be useful in different therapeutic contexts, do not specifically capture the innovative and theoretical essence of Kelly's method for construct modification. Role-playing scenarios and visualization techniques serve different therapeutic purposes, and journaling may assist in reflection but doesn’t quite align with the unique approach of introducing "preposterous interpretations" to facilitate change in personal constructs.
