This lesson focuses on understanding and exploring the concept of working memory through a practical exercise that simulates how our brain manages multiple tasks simultaneously. Participants are tasked with remembering five important items while also performing a counting challenge, helping to illustrate the concept of mental overload. The exercise leads into a reflection on the experience and introduces the idea of a 'Brain Dump', a technique for reducing mental clutter by transferring thoughts onto paper. This allows individuals to evaluate how clearing their minds affects their cognitive load and mental well-being.
