CONCENTRATE! I On Words & Concepts is a language, vocabulary enhancement, and memory improvement tutorial program designed to exercise short term memory, enhance word knowledge, foster cooperative play and provide recreational enjoyment for children and adults who have a developmental, physical, or language learning disability or autism, or adults with traumatic brain injury and aphasia. It is a series of educational games that reinforces the lessons of the Words & Concepts series (see separate entry) such as Vocabulary, Categorization, Word Identification by Function, and Word Association. The games use the same vocabulary as their corresponding Words & Concepts programs. Students may play alone or with another player. The object of the game is to find matches based on vocabulary, categorization, word identification by function, or word association. During play, the computer provides auditory instruction and feedback. A menu permits control of the number of cards on the screen, animation, number of players, and interface method used by each player. Interface options include TouchWindow (see entry), single switch, or keyboard. Scanning speed may be adjusted for single switch users.
