Bring the theories of learning to life using SNIFFY, THE VIRTUAL RAT! Instructors praise Sniffy, a realistic digital rat in an operant chamber (Skinner Box), for his ability to give students hands-on experience in setting up and conducting experiments that demonstrate the phenomena of classical and operant conditioning. Users begin by training Sniffy to press a bar to obtain food. Then, they progress to studies of more complex learning phenomena. Throughout each, a series of "Mind Windows" enables students to visualize how Sniffy's experiences in the chamber produce the psychological changes that their textbooks discuss in connection with learning. Available on a cross-platform CD-ROM, the Lite version of Sniffy includes 16 exercises that cover the essential phenomena of learning psychology? making it equally appropriate for psychology of learning and introductory psychology courses. The CD-ROM comes with a Lab Manual that walks users through the steps necessary to set up classical and operant conditioning experiments that closely resemble the experiments discussed in learning texts. (Screen shots are included for both Macintosh® and Windows users.) The manual also includes instructions on how to print or e-mail results, so that Sniffy can become part of students' homework assignments and term papers.Tom Alloway is the author of 'Sniffy the Virtual Rat Lite, Version 2.0 (with CD-ROM)', published 2004 under ISBN 9780534633578 and ISBN 0534633579.
