What methodology did Andrade use in her research?

• A. A qualitative survey of participants
• B. A controlled experiment with doodling tasks
• C. A case study of artists
• D. A longitudinal study of student engagement

Answer: (B)

Andrade employed a controlled experiment with doodling tasks to investigate the effects of doodling on memory retention and attention. This methodology allowed her to establish a direct cause-and-effect relationship by manipulating the doodling variable while controlling for other factors that could influence the outcomes. Through this experimental setup, she was able to systematically gather data on how doodling impacted participants' information recall, demonstrating its effectiveness as a cognitive tool. The controlled environment ensured that any observed changes in memory or attention could be attributed specifically to the act of doodling, providing strong evidence for her conclusions.
