The PORTL Laboratory.

Abstract

In the history of the field, behavior analysts have used the operant chamber as an apparatus for both teaching and experimental investigations. In the early days of the field, students spent significant time in the animal laboratory, using operant chambers to conduct hands-on experiments. These experiences allowed students to see behavior change as an orderly process and drew many students toward careers in behavior analysis. Today, most students no longer have access to animal laboratories. However, the Portable Operant Research and Teaching Lab (PORTL) can fill this void. PORTL is a table-top game that creates a free-operant environment for studying the principles of behavior and their application. This article will describe how PORTL works and the parallels between PORTL and the operant chamber. Examples will illustrate how PORTL can be used to teach concepts such as differential reinforcement, extinction, shaping, and other basic principles. In addition to its use as a teaching tool, PORTL provides a convenient and inexpensive way for students to replicate research studies and even conduct their own research projects. As students use PORTL to identify and manipulate variables, they gain a deeper understanding for how behavior works.
