Overview

About the Product

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 23 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.

Features

  • Reorganized to match the sequence of most learning textbooks, Sniffy Lite now allows teachers to teach classical before operant conditioning. This makes it easier for teachers to assign laboratory exercises.

  • Students can now teach Sniffy to perform tricks, such as grooming his face or sitting up and begging. Students can teach Sniffy to perform the desired behavior more frequently in the presence a light or a tone so that Sniffy performs the trick on cue.

  • A new "auto reinforcement" feature aids trick training. Students select the behavior they want reinforced, and a virtual "Lab Assistant" ensures that all occurrences of the target behavior are reinforced.

  • The program now incorporates a "movement monitor" that measures Sniffy's general activity and a Movement Ratio that indicates inhibition of movement (freezing) as a measure of classical conditioning. As in previous editions, once a user has trained Sniffy to press the bar, they can employ a Suppression Ratio as a measure of classical conditioning.

  • A simulation of the effects of punishment on extinction in operant conditioning is now included. This feature simulates several classic studies described in many learning books.

  • Sniffy software generates a digital cumulative record, which will improve students' and professors' ability to export numeric data.

  • The manual includes clear, user-friendly printing instructions to enable users to print data and graphs.

  • Sniffy now includes a "pause" feature so the student can take a break and pick it up when they come back, rather than having to start over.

  • Sniffy is a highly realistic, animated rat in a Skinner Box. He can be conditioned to perform tasks and tricks through classical and operant conditioning. Sniffy can be trained to press a bar or perform a variety of other behaviors to obtain food reinforcement.

New to this edition

  • New--Behavior frequency recording. Record the frequency with which Sniffy performs each of his twenty-two behaviors, users can see how training Sniffy to perform his "tricks" affects the frequencies with which he performs his behaviors, allowing for new observations of how maintaining Sniffy's operantly conditioned behaviors on different schedules of reinforcement affects the frequency of behaviors that are never reinforced.
  • Monitoring adjunctive behavior. Users can now demonstrate that reinforcing bar pressing on interval schedules of reinforcement produces "adjunctive behaviors," behaviors whose frequency is increased as a side effect of reinforcing another behavior on an interval schedule. When Sniffy's bar pressing is reinforced with food on an interval schedule, he drinks more often even though he is never reinforced for drinking (and he is not water deprived). Such increased drinking is called "schedule-induced polydipsia" and is the form of adjunctive behavior that psychologists have studied most extensively with real rats.
  • Increased usability. New user features include a redesigned and improved classical conditioning dialog box, more expandable windows, ease of multiple test case generation, ability to control sound-proofing level, automated "Isolate" mode option, and improved data export. Students' reinforcement actions will also be marked on the cumulative recorder to help cut down on student copying.
