Updates to 2nd Edition

With our first edition, we relied heavily on the foundation of the 2e Psychology text from OpenStax. Since our launch in spring 2020, we’ve made many changes. Some of these changes were relatively minor, while others have been more substantial. Below you will find a summary of the highlights of some of the key changes we’ve made, as well as upcoming revisions we have in the works.

  • Theme has been updated to better accommodate all learners (update to fonts, formatting, etc.)
  • Clearer distinction between sections/chapters
  • Dozens of updates to links for figures, Links to Learning, and other hyperlinks
  • Review and implementation of inclusive language (e.g., increase in gender-neutral language, inclusion of they/them in examples and vignettes, inclusive language around sex, development, and reproduction, etc.)
  • Addition of Indigenous perspectives, contributions, and historical injustices (e.g., Blackfoot and Mi’kmaw contributions and approaches to needs models, intergenerational trauma and Indian Residential Schools, memory techniques, etc.)
  • Edits throughout to increase conciseness, simplify language, update to Canadian spelling, etc.
