What theoretical model did Andrade reference to support her study on doodling?

Andrade referenced the working memory model to support her study on doodling because this model provides a framework for understanding how information is processed in our short-term memory. The working memory model, proposed by Baddeley and Hitch, divides memory into components that handle different types of information. This model posits that working memory is limited in capacity, which can influence how well we can maintain attention and process information simultaneously.

In the context of Andrade's study, doodling was seen as a way to occupy the central executive component of the working memory, which could potentially free up resources for the individual to focus more effectively on the primary task of listening. By using doodling to manage cognitive load, participants may have been able to enhance their overall information retention and recall, aligning with the principles of the working memory model that emphasize the importance of attention in memory tasks.
