Step 1: Understanding the Concept:
This question refers to the widely accepted model of the creative process, most famously articulated by Graham Wallas in 1926. The task is to identify the option that is not one of the stages in this model.
Step 2: Detailed Explanation:
Graham Wallas proposed a four-stage model of the creative thinking process:
1. Preparation: The initial stage where the problem is investigated from all directions. The creator gathers information, resources, and consciously works on the problem.
2. Incubation: A period where the problem is set aside, and no conscious work is done. The mind continues to process the information subconsciously.
3. Illumination: The "Aha!" or "Eureka!" moment. A sudden insight or idea flashes into the creator's mind, often when they are relaxed or engaged in an unrelated activity.
4. Verification: The final stage where the new idea is tested, elaborated, and applied to see if it works.
The option (C) Retention is a stage in the process of memory, which includes encoding, storage (retention), and retrieval. While memory is crucial for creativity, retention itself is not considered a distinct stage of the creative thinking process as defined by Wallas.
Step 3: Final Answer:
The stages of creative thinking are Preparation, Incubation, Illumination, and Verification. Retention is a stage of memory, not creative thinking. Therefore, Retention is the correct answer.
