The Mem-ExSpan Accelerative Cognitive Training System (MESACTS) is described as a cognitive skills training program for schools, businesses, and industry. The program achieves extraordinary academic results in reading and mathematics with 1 semester of input 4 days a week for 30 minutes a day. Intensive versions of the program accelerate information processing for individuals aged 10 years to adulthood. The program builds on the manuals, software, and workbooks of other cognitive skills training by adding auditory components to form an interactive multi-media technology. The system teaches left-brain sequencing of complicated information that is essential in mathematics, reading, writing, and critical thinking. When integrated with right-brain pattern detection skills, the system creates a method for rapidly encoding and decoding information. Research studies involving 583 subjects aged 10 years to adulthood demonstrate the effectiveness of the program. The MESACTS is useful in developing the cognitive skills needed for learning achievement. Fourteen references are included. (SLD)
