But with the right kind of practice, it’s possible to strengthen the connections between words and concepts and navigate your world more easily. “It will be a LONG time before you run out of content to use with one patient, and the app’s fantastic settings options will allow you to use it with a variety of individuals, regardless of cognitive abilities.” - Aubrey Klingensmith, MS, CCC-SLP, Speechie Apps GET THE RIGHT ACTIVITY - FOR EVERY BRAIN. No two people are the same. With 4 activities ranging from simple to complex, there's something in Category Therapy to match your needs. Work through them gradually or focus on the activity that best suits your needs. 1) FIND: Start with the basics. You'll hear and see a photo of a category (let's say "Fruit"). Tap the item that matches (for example, a banana). 2) CLASSIFY: Switch it up. Now you start with an item and choose the category that matches. This tests your ability to apply categories to what you see. 3) ADD ONE: Train yourself to recognize common features of items – to categorize them – and then choose one item that fits the category you’ve identified. 4) EXCLUDE: Challenge yourself. By choosing an item that doesn't belong, you learn how to independently identify categories. As things get harder, you can always tap Hint for some help. ALL DONE? Share your progress. The app makes it easy to quickly view, share, or e-mail detailed reports to a therapist or loved one. GET EVERY FEATURE YOU NEED IN ONE EASY APP. • 70 categories and nearly 700 words in one package • 3 difficulty levels ranging from simple objects to more abstract concepts • Great for aphasia, brain injury, autism, and other cognitive & language impairments • Switch to Pictures Only to practice naming or Words Only to practice reading • Customize the number of trials, choices, and more – it’s yours to control • Designed with adults in mind but easy enough for children to use • No subscriptions, no monthly bills, no Wi-Fi needed THERE’S HOPE.
