System requirements for IBM-compatible computers include a minimum Pentium II processor, Windows 98, 32 MB RAM, an 8× CD drive, 16-bit sound card, and a 600 × 800-color display. The software does not require much memory or hard drive space. Software installation is easy because it runs with few prompts after inserting the disk into the CD drive. Overall, this program has a strong potential for facilitating the instruction in undergraduate conditioning courses, serving as an addendum to traditional undergraduate conditioning laboratories and as a supplement to the use of live animals. On-screen presentations may keep most users interested, but working with the generated data files sometimes can prove difficult. In both Pavlovian and operant paradigms, one can generate histograms that predict the degree to which various stimuli control the virtual rat's behavior. Operant manipulations allow shaping the behavior of the virtual rat, observing cumulative records of interval and ratio schedules, as well as conducting operant discrimination procedures. Pavlovian effects such as blocking, overshadowing, and stimulus competition are demonstrated in the data output. Many of the standard conditioning paradigms and phenomena are contained within this program. It has an extensive set of simulations related to Pavlovian and operant conditioning. Sniffy the Virtual Rat Pro Version 2.0 is the most recent update to the Sniffy the Rat program modules.
