"The Tetris Mind – How repetitive tasks rewire your perception of reality" explores the "Tetris Effect." People who play the game for hours begin to see falling blocks in their sleep and visualize fitting buildings together on the street. This book argues that this is not just about video games; it is a fundamental feature of how the brain learns and filters reality. Psychologist Leonard Salt explains that whatever we dedicate our attention to—whether it is coding, complaining, or gratitude—creates a "cognitive afterimage." If you look for problems all day at work, you will scan for problems in your marriage. The brain becomes a pattern-matching machine for whatever you feed it. "The Tetris Mind" teaches readers to harness this neuroplasticity. It offers strategies to "play different games" with your attention, effectively reprogramming your subconscious to spot opportunities instead of obstacles.
