This is a free, open-educational textbook and set of course materials for an introductory undergraduate course in cognition. The materials are not yet complete, and I am continuing to develop them across the Fall 2021 and Spring 2022 semesters. All of the materials are CC BY-SA 4.0 creative-commons licensed and free for others to use, copy, remix, re-use.

The suite is developed using open-source software (R, RStudio, Bookdown). The source code for this project is available at

The suite includes:

  1. This textbook:
  2. A course website:
  3. Web-based slide decks for a one semester long course (see course website)
  4. An exam test bank (email

The above material is in various stages of development, and should be complete by 2022.

We have plans to continually revise, improve, and add to this suite. In particular, a major stretch goal for the textbook is to embed lab activities in the form of web-based experiment demonstrations, and data-analysis demonstrations. Another goal is to develop tutorials showing others how to copy, use, and/or collaborate on content development.
