How did Andrade assess the effectiveness of doodling?

• A. Through surveys about students' feelings
• B. By comparing doodlers and non-doodlers' performance
• C. By observing doodling frequency in class
• D. Through interviews with students

Answer: (B)

Andrade assessed the effectiveness of doodling primarily by comparing the performance of doodlers and non-doodlers during cognitive tasks. This method allowed for a direct analysis of whether engaging in doodling had a measurable impact on the participants' ability to retain information and their overall task performance. By examining the differences in outcomes between those who doodled while listening to a lecture and those who did not, Andrade was able to draw conclusions about the cognitive benefits of doodling, such as improved memory recall. This comparative approach highlights the significance of doodling as a technique that can enhance learning and retention, positioning it as more than just a distraction. The focus on performance metrics provided concrete evidence supporting the argument that doodling can be beneficial in educational settings.
