Strong Mind Puzzles update provides progressively difficult variations. This encourages deliberate rehearsal and enhances learning. The rules, graphics, number of icons, and abstract images become more complex. Individuals must use the voice in their head to match the goal and complete the game. The voice in our head (internal dialogue) builds executive skills because it helps: * reduce impulsivity * contributes to planning behavior * encourages introspection and reflection * provides a system to generate alternatives This updates include all previous Strong Mind Puzzle Variations. The user is able to control their starting point and progression. The user has the flexibility of moving between games to individualize their learning experience. — Strong Mind Puzzles is a game designed to challenge your brain. In her 35 years of cognitive restructuring practice, Dr. Markus created a series of paper-and-pencil puzzles to explore new ways to challenge the brain and rehearse cognitive abilities. To reach beyond her clinical practice, these puzzles were converted to a mobile format which provide numerous, varied opportunities for learning. Effective problem-solving and decision-making is based, at least in part, on the number of variables a problem solver or decision maker is capable of evaluating. With deliberate rehearsal, individuals can learn to increase the number of variables that they use to make a decision. -- Why Finding Mistakes Develops Critical Thinking Behaviors Strong Mind Puzzles can help reduce mistakes. Think about what happens when you make a mistake. You become emotionally attached to the mistake. As a result, this emotional investment makes it difficult to examine results objectively. Such reasoning helps explain why we are better at catching other people's mistakes than our own errors. These puzzles give you practice in identifying and learning to anticipate errors. When you are comparing and contrasting images you search for mistakes. With practice, this develops an error-detection reflex.
