Experience LAMP Words for Life® Discover, the new, risk-free way to try all the features of the popular LAMP Words for Life app before you buy. After downloading, you’ll have the option to start a free 30-day trial OR to explore the LAMP Words for Life lite-tech board. LAMP Words For Life® is a robust augmentative and alternative communication (AAC) app that combines the power of Minspeak, the Unity® language system and Language Acquisition through Motor Planning (LAMP™) principles and strategies. LAMP is a therapeutic approach based on neurological and motor learning principles that addresses the language development and communication needs of individuals with autism and other developmental disabilities. It provides a consistent motor pattern per word so that automaticity can develop. With thousands of frequently used words pre-stored and the ability to store customized vocabulary, the app allows for unlimited language growth opportunities. With the focus on access to individual words, the communicator can put words together to express their own thoughts in a manner consistent with normal language development. It is appropriate for anyone from beginning communicators who are just learning that they can affect those around them to skilled communicators with advanced language skills. Language development in typically developing children occurs through the combination of a consistent motor pattern, the sound that motor pattern produces, and the reaction they get from the environment. LAMP Words for Life presents vocabulary in the same manner so those language connections can be developed. LAMP Words for Life app is symbol based for those who are not yet literate; however, those symbols are paired with text to support literacy development. The vocabulary, structure, and teaching approach are based on research and clinical experience. After your 30-day trial ends, you’ll have the option to purchase LAMP Words for Life. If you don’t make a purchase, you’ll still have access to the LAMP Words for Life lite-tech board when your trial period ends.
