A clinical-grade brain training exercise that develops the ability to view information from multiple perspectives — the cognitive flexibility behind problem-solving, creative thinking, and adaptive decision-making. Designed by Dr. Donalee Markus, a Northwestern-trained neuroscientist with 40 years of clinical practice in cognitive restructuring. WHAT IT TRAINS • Multi-perspective thinking — viewing the same situation from different angles • Spatial reasoning and attention to detail • Holding multiple variables in mind simultaneously • Creative problem-solving and adaptive thinking • Carryover skills that improve daily decision-making WHO IT'S FOR • Concussion and TBI recovery (especially patients with executive-function challenges) • Stroke rehabilitation • Adults wanting sharper problem-solving and adaptive thinking • Professionals whose work demands cognitive flexibility • Students working on critical-thinking skills THE SCIENCE Cognitive flexibility — the mental ability to switch between perspectives, tasks, and frames of reference — is one of the executive functions most affected by traumatic brain injury and aging. It's also one of the most trainable. Strong Mind Treasure Hunt provides the hierarchical, varied practice the brain needs to rebuild and strengthen this capacity. ABOUT THE DEVELOPER Dr. Donalee Markus has practiced cognitive restructuring since 1983, with institutional clients including NASA, Los Alamos National Laboratory, and the U.S. Federal Court System. Her work is featured in Clark Elliott's "The Ghost in My Brain" and in peer-reviewed publication in Physical Medicine and Rehabilitation Clinics of North America.

CHILD SAFETY Where is Ploppy?, a colorful fun hidden object game for everyone, is designed with your child's safety in mind. In addition to Apple's guidelines for children's games, we go one step further and firmly believe that any data about your children belongs exclusively to you and your children and should stay that way. Therefore, Where is Ploppy? does not store any of your children's data! There are additional security mechanisms in place to prevent your child from being routed out of the app while playing. This means that as soon as a link is called up, such as to rate the game, a short math problem must be solved beforehand. Furthermore, the game is also designed for the colorblind and children who can't read yet. So, if you are looking for a game that you can give to your children without hesitation, where they can also train their memory, then download Where is Ploppy? now! :) DESCRIPTION A game where you have to find a wanted Ploppy. It can be played over and over again. HOW TO PLAY At the beginning of the game you see a card which Ploppy is wanted. After pressing play, the Ploppies on the board get mixed up all over the place.

In the menu you can randomize the wanted Ploppy as often as you want. FEATURES - No advertisements - Offline playable - Kids-friendly designed - can be played by everyone even the youngest ones who cannot read yet - Endless gameplay by randomized cards - Sticker Pack included - share the Ploppies with family and friends via iMessage Terms of Use: https://www.tempuno.com/terms/where-is-ploppy/
