PORTL stands for the Portable Operant Research and Teaching Lab.

It provides an interactive environment for learning about behavior principles and investigating behavioral phenomena.

The nearly 50 exercises in this manual can be used to model a wide-range of behavior analytic concepts and principles. They will also help you improve your shaping and problem-solving skills. By the final chapters, you will have the skills to conduct your own inquiry and research projects.

The manual is divided into four main sections:

  • The first part of the manual introduces you to the game of PORTL. It introduces several sample curricula that can be used as you go through the manual. You will learn what supplies you need to play PORTL, learn how to set up the teaching environment, and practice the PORTL reinforcement system.
  • The second part of the manual will teach you about differential reinforcement and shaping. The six shaping foundation exercises in Chapter 4 will help you see the component pieces that make up larger behaviors and let you practice teaching these components. As you practice these exercises, your shaping skills and problem-solving skills will improve.
  • The third part of the manual will allow you to model a variety of different principles and concepts using PORTL. This includes schedules of reinforcement, stimulus control, concepts, and behavior chains. As you complete these exercises, you will discover more about how behavior works.
  • The fourth part of the manual will acquaint you with errorless learning, inquiry projects, and research projects. The skills you have practiced in the earlier chapters will come together as you learn how to teach behaviors with minimal errors and practice using PORTL to ask and answer your own questions about behavior.

You will need minimal instructions to start playing PORTL. However, as you gain more experience with the game, you can use it to ask and answer complex questions about behavior.


To play PORTL, you will need your own PORTL kit.

Each kit contains:

  • 30+ small objects
  • A clicker
  • 10 reinforcer blocks
  • A small bowl to collect and store the reinforcer blocks
  • Playing cards to use as cues
  • A storage pouch

Please note: The photos above show a sample PORTL kit. The 30+ small objects in each kit will vary from what you see pictured here. Items may differ based on color, size, or type. However, we will select an assortment of items for each kit that will be conducive for shaping different actions and for completing the exercises in the manual.
