Speak Spanish in ten days! Dr. Paul Pimsleur One of the world's foremost authorities in applied linguistics, Dr. Pimsleur revolutionized the teaching of languages with his theories of Phonetics and Phonemics, first developed at UCLA. He refined his instructional techniques while heading language programs at Ohio State University, the State University of New York at Albany, as a Fulbright lecturer, and as a founding member of the American Council on the Teaching of Foreign Languages. The Simplest, Most Effective Language Course Ever Developed! Using the unique method developed by Dr. Paul Pimsleur, you will learn a language the way native speakers do-through exposure to vocabulary, grammar, and pronunciation all at once, in phrases and conversational speech. And by applying Dr. Pimsleur's two key proven principles-the Principle of Graduated Interval Recall and the Principle of Anticipation-this program delivers results faster and more effectively than any other language-learning method-whether classroom or packaged. The Principle of Graduated Interval Recall-This is a complex name for a very simple theory about memory. In his research, Dr. Pimsleur discovered how long students remembered new information and at what intervals they needed to be reminded of it. If reminded too soon or too late, they failed to retain the information. This discovery enabled him to create a schedule of exactly when and how the information should be reintroduced.
