The Cognitive Crime Lab

Our Learning Goal

This Is a Study Aid, Not a Textbook Replacement

One sentence, as plainly as we can put it:

The Cognitive Crime Lab is built to augment what you're already learning in your Psychology 101 course — not to replace your textbook, your instructor, or your class time.

What that means in practice

Every Evidence Bag reviews material your course is almost certainly already covering, using the same general chapter sequence found in the most widely used introductory psychology textbooks. It exists to give you a second, more interactive way to review and check your own understanding — short concept reviews, retrieval-practice questions, and a capstone challenge — in a format closer to how people your age already study and play, rather than a static page of text.

It is not a substitute for reading your assigned chapters, attending lecture, or doing the graded work your instructor assigns. Treat it the way you'd treat flashcards, a study group, or a review app: a tool that sits alongside your coursework, not one that stands in for it.

Why we built it this way

Research on learning consistently finds that actively testing yourself on material — not just re-reading it — is one of the most effective ways to make it stick; this is often called the "testing effect" or retrieval practice. Spacing that practice out, and connecting new material back to what you've already learned, both strengthen retention further. That's the whole design behind the Evidence Board: short, active review per chapter, with each new chapter deliberately reaching back to test concepts from chapters you've already completed, rather than treating each one as an island.

On accuracy

Every Evidence Bag cites the specific chapter or section of OpenStax Psychology 2e (a free, peer-reviewed introductory psychology textbook) that it's based on, alongside the American Psychological Association as a general authority — the same sourcing standard this project has held since its first release. If something here ever conflicts with what your instructor or textbook says, defer to your instructor and your assigned textbook — they're the source of record for your course and your grade.

A note on Evidence Bag 14

Evidence Bag 14 (Psychological Disorders) is intentionally conceptual and educational — definitions, classification, and a general model of why disorders develop. It is not a diagnostic tool, and nothing in it is meant to be used to self-diagnose or diagnose anyone else. If you or someone you know is struggling, please talk to a mental health professional, a campus counseling center, or another trusted resource.
